SOFTWARE UPGRADE PROCEDURES

The following sections contain information for upgrading to the 6.0R8 software version. In particular, there are sections that describe the following:

• Standard Software Upgrade Procedure

Procedure for performing a standard, service-affecting upgrade.

Note: The following USB models from Sandisk are supported:

• Cruzer Fit – size 4GB and 8GB

• Cruzer Blade – size 4GB and 8GB

STANDARD

SOFTWARE

UPGRADE

PROCEDURE

This section describes the standard software upgrade procedure which is service-affecting:

• Each software release includes a boot loader (boot.tim) and the software image (both.tim).

• The boot loader initiates the loading of the 7210 SAS OS image based on the boot optionfile (bof.cfg) settings.

The following steps describe the software upgrade process:

Step 1. Backup existing images and configuration files

New software loads may make modifications to the configuration file which are not compatible with older versions of the software.

Step 2. Copy 7210 SAS-T images to cf1:

The 7210 SAS-T image files must be copied to the cf1: device on the 7210 SAS-T node. It is good practice to place all the image files for a given release in an appropriately named subdirectory off the root, for example, cf1:\6.0R8. Copying the boot.tim and other files in a given release to a separate subdirectory ensures that all files for the release are available should downgrading the software version be necessary.

Step 3. Copy boot.tim to the root directory on cf1:

The BOOT Loader file is named boot.tim. This file must be copied to the root directoryof the cf1: device.

Note:

• Alcatel-Lucent recommends making backup copies of the BOOT loader (boot.tim), software image and configuration files, should reverting to the old version of the software be required.

Page 2 Alcatel-Lucent


Step 4. Modify the boot options file to boot the new Image

The Boot Options File (bof.cfg) is read by the BOOT Loader and indicates primary, secondary and tertiary locations for the image file. The bof.cfg should be modified asappropriate to point to the image file for the release to be loaded. Use the bof save command to save the Boot Options File modifications.

Step 5. When upgrading to 7210 SAS 6.0R8, execute the admin reboot upgrade command. Note that, executing 'admin reboot upgrade' command system will upgrade the bootrom.

Allow the boot sequence to complete and verify that the card comes up.

If the user forgets the BOF password and fails to provide a correct password, after three attempts, the system prompts the user to reset the BOF password to factory default. If user accepts BOF password recovery, as a security measure, the system also resets the flash to factory defaults (that is, it removes all the files from the flash except the boot image file (cf1:\boot.tim) and Timos image file (cf1:\both.tim)) and reboots the node with the factory default settings.

Note:

• The 7210 SAS-T other drives such as "cf2:" or "uf1:" can also be used for storing boot.tim image. Note that the valid "bof.cfg" file is in the same drive from where the boot.tim is used. Order of search for boot loader is cf1:/boot.tim, cf2:/boot.tim, uf1:/boot.tim. bof.cfg is read from the drive where boot.tim is loaded.

• If it is not possible to overwrite cf1:\boot.tim file, Change the cf1:\boot.tim attributes using file attrib -r cf1:\boot.tim command.

RESOLVED ISSUES

NOTE:

• Issues marked as MI might have had a minor impact but did not disturb network traffic

• Issues marked as MA might have had a major impact on the network and might have disturbed traffic

• Issues marked as CR were critical and might have had a significant amount of impact on the network

RESOLVED INR6.0R8

The following are specific technical issues that have been resolved in Release 6.0R8 of the 72SAS-T OS.

• In Y.1564 test results, the average latency values are shown as junk values, if the actual average latency values are in the order of few tens of millisecond. This is resolved in 7210SAS 6.0R8 release. [193843-MI]

• In a scaled IGMP snooping configuration, few membership report packets may get droppewhen the system receives them at a very high rate and consistently for a longer duration. Sofar, this was seen only in a simulated lab environment. This is resolved in 7210 SAS 6.0R8release. [194068-MI]

RESOLVED INR6.0R7


• System was allowing to remove a trap-target from a snmp-trap-group even if that particulartrap-target is configured under “snmp-dying-gasp”. Execution of such saved configurationerrored out. This is resolved. [182398-MI]

• With Tacplus configuration, a non-harmful message "Slot A: aaaUnlockX:semGive failed" is fixed. [182400-MI]

• “snmp-dying-gasp” trap may not use system ip address as source-ip, with certain sequencof “snmp-dying-gasp”, source address, and system-ip configurations. This issue is resolved. [188404-MI]

• With previous release, newly booted SAS-T box with no config allowed only 128 hmetersinstead of 256, issue was not observed if booted with config file. Issue is resolved. [190997-MI]

• On 7210 SAS-T, under certain link failure conditions, operational speed of 1Gig fixed copper port downgraded to 10Mbs. This issue is resolved. [184258-MI]

RESOLVED INR6.0R6


• In earlier 6.0 releases, on a SAP with aggregate-meter-rate configured, modification of attached ingress-qos policy-id to a different ingress-qos-polcy-id can cause any other sap

meter or aggregate-rate-meter values not honored. Impacted sap can be in the same servior other service. Due to this, impacted saps hierarchical meters may operate at lower or higher value than the one configured on that sap. If the operating meter values are lower than the configured value, traffic drop on that SAP can be observed. This issue is resolvein 6.0R6. [180835-MA]Workaround: Remove the aggregate-meter-rate configuration on all the SAPs and Re-configure the aggregate-meter-rate.

• If ingress IP filter applied on IES SAP with default action drop, any CPU transmitted IP packets on this SAP are dropped, if these ip packets doesn't match any of the entry matchcriteria. This issue is resolved. [180336-MA]Workaround: To configure default action as forward and add additional entry with "match any, action drop" as the last entry in the IP-filter.

• If IPv4/UDP or IPv6/UDP packets with UDP destination port value equal to 3784 and IP TTL value is not equal to 255 or 1 is received on any service was causing protocols on thsystems to go down. This issue is resolved. [179609-MA]

• A fix is provided to prevent the high CPU issue when DDM register read fails. An error message is displayed if DDM read fails. [177598-MI]

• In CLI context "sap->statistics->ingress" if "received-count" is removed then CLI contextfor "counter-mode forward-drop-count" was wrong. Execution of such saved config file errors out. [176390-MI]

• During boot "no" form of CLI (For example: "no uplinkA-route", "no uplinkA-vlan") defined in bof.cfg will not be recognized, such configuration was resulting in boot loop. This issue is resolved. [175678-MI]

• 10Gig XFPs with the part code SXP3100SX-A8 is supported. [104832-MI]

• In 6.0R6 release issue with setting "max-burst" value with port ERL is resolved.[173129-MI]

• Delay mesurement was not proper using TWAMP with PTP enabled in previous 6.0 release. This issue is resolved now.[177621-MI]

• When using the TACACS+ server for authorization commands could be authorized incertain cases when they should be blocked. This issue has been resolved in 6.0R6 [153403-MI]

• Deleting IES SAP results in console messages is resolved in 6.0R5. [165261-MI]

RESOLVED INR6.0R5


• 7210 SAS-T from 6.0R5 release supports:

- Y.1731 2DM, 1DM and SLM delay measurement for UP MEP.

- Y.1731 1DM and SLM delay measurement for DOWN MEP

Note that the above tests use time stamp:

- From NTP, if NTP is enabled and PTP is disabled. OR

- From PTP, when PTP is enabled (irrespective of whether NTP is disabled or enabledOR

- From free-running system time, if both NTP and PTP are disabled.

However, once PTP is enabled and the user prefers to go back to NTP time scale, or system frerun time scale, a system reboot is required.

• 2DM for DOWN MEP was supported in earlier releases. [164660-MI]

• 7210 SAS-T supports TWAMP functionality from 6.0R5 release. [165059-MI]

• In previous release deleting IES SAP resulted in console messages, this issue is resolved6.0R5 release. [165261-MI]

• The state of the Tacacs+ server will no longer go down when the user abruptly terminatesthe session without logging off. This issue was only observed when tacacs accounting waconfigured. [172625-MI]

• If CPU targeted IP/UDP fragmented packet has 0x0401 value at offset 22, it was dropped in previous releases. If an SNMP request packet is fragmented and matches to this, synchronization with SAM can fail. This is resolved in 6.0R5. [169210-MA]

RESOLVED INR6.0R4


• In previous release of 7210 SAS, "config>service>vpls>sap>igmp-snooping>disable-router-alert-check" was not saved with "admin save". This issue is resolved. [163701]

• In 6.0R3 release 7210 SAS-T CBS and MBS of meter max was 16384, in 7210 SAS 6.0R4max value is 2146959. [164822-MI]

• In previous release of 7210 SAS, the egress queue CBS for the access uplink port configured with ERL changed from 1.7KB upto 8KB after an admin save and reboot. Thisissue is resolved.Work around for this issue would be to remove the ERL for the port and add it back. [165281-MI]

• In previous releases of 7210 SAS, if the user configured a retention period for accounting records greater than the default value, during a system reboot, the accounting files that hathe actual retention period greater than the default retention period were deleted. This issuis resolved. [159600-MI]

• The "tools dump system resources" shows huge value as free for "UP MEP entries" in previous release of 7210 SAS. This issue is resolved. [165201-MI]

• In previous releases of 7210 SAS 6.0, the "show port <port-id> optical" output was not displayed. This issue is resolved. [167166-MI]

NEW FEATURES

RELEASE

6.0R8There no new features added to 6.0R8 of the 7210 SAS-T OS.

RELEASE

6.0R7There no new features added to 6.0R7 of the 7210 SAS-T OS.

RELEASE

6.0R6The following items describe features added to 6.0R6 of the 7210 SAS-T OS.

1588V2/PTP Platforms Supported: 7210 SAS-T

The 7210 6.0R6 release supports use of 1588v2/PTP for frequency and time recovery. It

supports both OC slave and BC with IEEE default profile and ITU-T G.8265.1 frequency profile.

Following are some of the restrictions.

• PTP Hybrid mode is not supported

• Change of clock-type for OC slave to BC or vice-versa requires a reboot of the node for thchange to take effect

• IP source address to use must be configured under configure> security> source-address> ptp, before PTP can be used. PTP uses the configured IP address as the source IP addressthe PTP messages generated by the node. It is recommended to configure either the systemIP address or the loopback IP address for use with PTP. For more information, see the 721SAS Basics System Configuration User guide.

1830 VWM(CWDM)

MANAGEMENT

Platforms Supported: 7210 SAS-T.

The 7210 6.0R6 release adds support for management of the 1830 VWM (CWDM) device using the OMC port on 7210 SAS-T. Prior releases supported management of the 1830 VWM (CWDM) device using the USB port only on 7210 SAS-E, 7210 SAS-M, and 7210 SAS-X In addition to the basic inventory management support available in the previous releases, this release adds supports for provisioning of cards inserted into the slots available on the 1830 devices. The user must provision the card and card-type (also known as, module type) beforethe card can be managed by the 7210 SAS. The 7210 SAS detects and reports mismatch in provisioning of the card. It also detects and reports insertion and removal of the card/modulefrom the slot on the 1830 device. Please read the 7210 SAS Systems Basic user guide for morinformation.

PER PORT MBS AND

ALLOCATION OF

EXTRA EGRESS

QUEUE BUFFERS

PER PORT

From release 6.0R6 7210 SAS-T supports two modes of sharing the mbs buffer pool:

• Mode-1 (a.k.a. per-node MBS pool):MBS Buffer pool shared globally by all port queues. This mode is default one and supported in previous releases also.

• Mode-2 (a.k.a, per-port MBS pool): Buffer pool divided equally among all the ports in thesystem. Some of these buffers are allocated towards the CBS and the rest is assigned to thper port MBS pool.

Per port mode is configured using “configure system resource-profile qos mbs-pool port”. Thenode must be rebooted for the per-port mode to take effect. Changing Mode-1 to Mode-2 or viceversa requires saving configuration and a reboot of the node.

From 7210 release 6.0R6, with per-port MBS pool mode, user is provided with an option to make efficient use of the available port egress queue buffer pool by allocating queue buffers othe unused ports to in-use ports configured to deliver services. User is provided with a CLI command to decommission a port and make it unavailable to deploy services. Software will notallocate any queue buffers to these decommissioned ports and instead will assign it to a specifiport or a group of ports configured by the user. This mechanism allows operators who use limited number of ports to deploy services, to increase the amount of queue buffers allocatedthem by decommissioning ports not used to deploy services.

The user will have an option to specify a port or a groups of ports which will receive the creditof queue buffers freed up using the decommission command. For example, it will be possible for user to configure decommissioning of 4 ports and allocate the freed queue buffers to the remaining ports in the system or decommission 5 ports and allocate the freed up queue buffeto the 10G XFP ports, and so on. This mechanism allows the operators to provide higher amounof queue buffers to a specific port or a group of ports, allowing them to pick and choose portsthat need the extra buffers for burst absorption.

The amount of credit of queue buffers received by a port will be used to increase the MBS portion of the buffer pool of the port. This allows any queue on the port to use the buffers, ifneed be. The CBS portion of the queue is not modified with this feature. The system has to brebooted after decommissioning of ports for the queue buffers to be reallocated and the configuration to take effect.

NOTE: Decommission commands do not take effect when the node’s mode is set to per-nodeMBS pool. It is available for use only when the node’s mode is set to per-port MBS pool.

For more information, see the 7210 SAS-T QoS guide and 7210 SAS-M,T, and X Basic Systems User Guide.

L2PT Platforms Supported: 7210 SAS-M (in both access-uplink and network mode), 7210 SAS-D and 7210 SAS-T.

With this release, L2PT support in a VPLS service has been enhanced to include support forCDP, VTP, DTP, UDLD, and PAGP. This enhancement is available for 7210 SAS-D, T, and Min both access-uplink and network mode. For more information, see 7210 SAS Services Guide

RELEASE

6.0R5The following items describe features added to 6.0R5 of the 7210 SAS-T OS.

EPIPE OPER STATE

DECOUPLING

Platforms Supported: 7210 SAS-M (in both access-uplink and network mode), 7210 SAS-D and 7210 SAS-T.

In 7210 SAS release 6.0R5, the user can now configure a single SAP in an Epipe that allows thoperational state of the Epipe to remain up, even when the SAP enters a failed operational dowstate. There is no indication that the service is unable to forward transit traffic when this condition is active. This is only applicable to Epipes that exclude alternate egress points (forexample: MC-LAG with ICB). LAG SAPs are supported.

For more information, see the 7210 SAS Services user guide.

Y.1564 TESTHEAD Platforms Supported: 7210 SAS-X and SAS-T

7210 Y.1564 testhead OAM tool supports bi-directional measurement and it can generate tetraffic for only one service at a given time. Testhead OAM tool can be used to perform out-oservice tests for VPLS and Epipe services. It can validate if the user specified rate (only CIR support is available in this release) is available and compute the delay, delay variation and losfor the service under test at the specified rate. It is capable of generating traffic up to about 1Grate.

The user needs to dedicate the resources of a front-panel port on 7210 SAS-X for use with testhead feature, for SAS-T either front panel or internal ports (ports 1/1/27, 1/1/28) can be useAdditionally, port loopback with mac-swap must be used at both ends and all services or SAPon the test port will need to be shutdown before using the testhead. For more information, se“7210 SAS M,X,T OS OAM and Diagnostics Guide”.

NOTE: For 7210 SAS-T and SAS-X, user must allocate resources to egress ACL MAC or IPv4or IPv6 64-bit criteria (using the command "config>system> resource-profile> egress-internal-tcam> acl-sap-egress> mac-ipv4-match-enable or mac-ipv6-64bit-enable or mac-ipv4-match-enable"). If user allocates resources to egress ACLs IPv6 128-bit match criteria (using the command config> system> resource-profile> egress-internal-tcam> acl-sap-egress> ipv6-128bit-matchenable), then testhead will fail to function.

In addition for 7210 SAST the user must configure resources for ACL MAC criteria in ingress-internal-tcam using the command "config>system> resource-profile> ingress-internal-tcam> acl-sap-ingress> macmatch-enable". Equivalent resource or SAS-X will be used from external tcam.

Testhead tool uses resources from these resource pools. If no resources are allocated to thesepools or no resources are available for use in these pools, then testhead will fail to function. Testhead needs a minimum of about 6 entries from the ingress-internal-tcam pool for SAS-T orexternal tcam for SAS-X and 2 entries from the egress-internal-tcam pool.

1588V2/PTP (BETA

ONLY)Platforms Supported: 7210 SAS-T

The 7210 6.0R5 release supports use of 1588v2/PTP for frequency and time recovery. It supports both OC slave and BC with IEEE default profile.

Following are some of the restrictions.

• ITU-T G.8265.1 frequency profile is not supported

• PTP Hybrid mode is not supported

• Change of clock-type for OC slave to BC or vice-versa requires a reboot of the node for thchange to take effect

• IP source address to use must be configured under configure> security> source-address> ptp, before PTP can be used. PTP uses the configured IP address as the source IP addressthe PTP messages generated by the node. It is recommended to configure either the systemIP address or the loopback IP address for use with PTP.

For more information, see the 7210 SAS Basics System Configuration User guide.

VLAN RANGE SAPIN VPLS SERVICE

Platforms Supported: 7210 SAS-M (only access-uplink mode), 7210 SAS-D and 7210 SAS-T

Currently, the 7210 SAS platforms support use of Dot1q range SAPs with only Epipe servicesin either network/MPLS mode or access-uplink/L2 mode. Dot1q range SAPs allow operators ttransport a range of VLANs by providing similar service treatment to all of the VLANs configured in the range. It eases service configuration and allows operators to scale the numbof VLANs that can be handled by the node. When MPLS mode is deployed in ring topology, operators have the option of using different redundancy mechanisms such as FRR, primary/secondary LSPs, Active/Standby PWs and others. To improve Epipe service availability, while no such option is available in prior releases to protect Epipe service in L2 mode when deployed in ring topology. The 7210 6.0R5 release allows operators to deploy Epipservices in a ring topology when using L2 mode, by emulating an Epipe service using a VPLSservice with G8032 protection and at the same time provides the benefits of using dot1q rangSAPs.

Even though a VPLS service is used for this, it is expected that the user should ensure throuconfiguration that it is a point-to-point service. This can be achieved by configuring a VPLS service with an access dot1q range SAP used for customer handoff on one node in the ring anan access dot1q range SAP for customer handoff in an VPLS service on another node (i.e. at thother end of the Epipe), such that are only two endpoints for the service in the network. On thenode where the service originates, in addition to the access dot1q range SAP, the service neeto be configured with access-uplink SAPs on the two G.8032 ring ports. The G.8032 mechanismis used to for breaking the loop in the ring and VPLS service protection. The intermediate nodeon the ring will need to use VPLS service with access-uplink SAPs on the ring ports and use thsame G.8032 instance for protection as the one used for service protection on the originating node.

The VPLS service with dot1-range SAPs use svc-sap-type of dot1q-range and supports the following functionality in comparison to a normal VPLS service.

• Allows user to define an access dot1q range SAPs, which specifies a group of VLANs which receive similar service treatment, i.e. forwarding behavior, SAP ingress QoS treatment and SAP (behavior similar to that available in Epipe service).

• In an epipe service, 7210 does not check if the inner tag received on a Q1.* SAP is withinthe range of the configured VLANs, when the packet is sent out of the dot1q range SAP. This is true for VPLS services too. It is up to operators to make sure they do not mix services.



to

e

• G.8032 mechanism can be used for loop detection in ring network and service protection. Aseparate VPLS service representing the G.8032 control instance must be configured and itsstate must be associated with this service. Support for xSTP is not available.

• Broadcast, Unknown Unicast and Multicast (BUM) traffic is flooded in the service

• Learning is enabled on the service, by default, to avoid the need to flood the service trafficout of one of the ring ports, after network MAC addresses are learnt. User has an option disable learning per service.

• MAC limiting is available per service and is not available per SAP

• CFM OAM support is available. Only UP MEPs can be configured on the dot1q range SAPin the service using a primary VLAN and used for fault management and performance management using the CFM/Y.1731 OAM tools. Support for Down MEPs and MIPs are not available.

• BPDU translation and L2PT support is not available

• L2 control protocol (L2CP) tunneling support is not available

• IGMP snooping and MVR is not supported.

The 7210 6.0R5 release adds support for management of the 1830 VWM (CWDM) device using the OMC port on 7210 SAS-T. Prior releases supported management of the 1830 VWM (CWDM) device using the USB port only on 7210 SAS-E, 7210 SAS-M, and 7210 SAS-X

In addition to the basic inventory management support available in the previous releases, thisrelease adds supports for provisioning of cards inserted into the slots available on the 1830 devices. The user must provision the card and card-type (also known as, module type) beforethe card can be managed by the 7210 SAS. The 7210 SAS detects and reports mismatch in provisioning of the card. It also detects and reports insertion and removal of the card/modulefrom the slot on the 1830 device. Please read the 7210 SAS Systems Basic user guide for morinformation.

NOTES:

• A maximum of up to 2 1830 CWDM devices can be managed using the OMC port

• On 7210 SAS-T, the USB port cannot be used to manage the 1830 VWM device

Notes:

• The buffer allocation on 7210 SAS-T is different compared to 7210 SAS-D/M. 7210 SAST allocates CBS amount of packet buffers per queue and a MBS pool of packet buffers pernode. This MBS pool is shared by all the queues in the node and can be allocated towardthe queue’s MBS amount of buffers. For more information, see 7210 SAS-M and 7210 SAS-T QoS user guide.

• 7210 SAS-T supports the following options for booting the node:

- Using autoinit

- Using internal flash (cf1:\)

- Using external flash (cf2:\)

- Using USB port (uf1:\)

• 7210-T ETR requires 200W power supply.

When shipped from factory the device is configured to use autoinit by default. Please see the7210 SAS-T Installation Iuide and 7210 SAS-T Basics System guide for more information onhow to use the various options to boot the 7210 SAS-T device.

ENHANCEMENTS

RELEASE

6.0R8There are no new enhancements added to the 7210 SAS-T OS in release 6.0R8.

RELEASE

6.0R7There are no new enhancements added to the 7210 SAS-T OS in release 6.0R7.

RELEASE

6.0R6The following item describe enhancements added to the 7210 SAS-T OS release 6.0R6.

CFM NAMES With this release, support has been added to allow the 802.1ag MA name formats to be configured for Y.1731 MEP.

RELEASE

6.0R5The following item describe enhancements added to the 7210 SAS-T OS release 6.0R5.

• From 7210 SAS release 6.0.R5, the ifAlias value within the IfXEntry MIB table is set based on the description string configured under the associated port or logical interface. Aa result, ifAlias is different from the value returned in the ifDescr field as the system's port/interface name and type are not prepended to the ifAlias value. [172105]

KNOWN LIMITATIONS

• 7210 SAS may reboot or become un-responsive if non-supported USB devices are connected.Note: The following USB models from Sandisk are supported:

- Cruzer Fit – size 4GB and 8GB

- Cruzer Blade – size 4GB and 8GB

• In Testhead jitter and latency values are provided only when the test traffic encapsulation issame as test SAP, for example, Q1.Q2 doubly tagged traffic is used if test sap is of Q1.Q1 encapsulation. [152369]

• With default action “drop”, if CPU bound packet does not match none of the entry matchcriteria, these packets are still forwarded to CPU. The workaround for this is, configure a entry criteria with match any and action drop as the last entry in the IP-filter. [180336]

• SHG can be configured either in “mvr vpls-service” or “user vpls-service”, but not in both.

• The user is recommended to protect the out-of-band (OOB) Ethernet management interfaceto avoid high CPU utilization when high-rate of traffic (For example: High rate of traffic due to DoS attach, high rate of broadcast traffic due to network miss configuration, and soon) is received on that interface. The system does not rate-limit ingress traffic on the OOBport and users should use other mechanisms to achieve this process. Management Accessfilters can be used to filter traffic destined to CPU, but uses CPU resources and cannot bused to drop high-rate of ingress traffic on the OOB port.

• During congestion in the system , and if a queue is not able to get shared buffers to hold aleast number of packets equal to weight configured, then the configured weights cannot bguaranteed. [163712]

• Egress ACL stats are not working in a null-star service for null Star,0.* sap,:* sap,:0 sap, however ACL functionality works. [122804]

• User has to make sure at least 1 ACL entry is free for the ACL re-numbering or copy functionality to work. [164279]

• The “detail” option for “admin save” command is not supported. Default values under anyCLI context can be viewed by using “info detail” command.

• On SAP ingress use of SAP ingress QoS policy with MAC criteria is mutually exclusive to use of ACLs with IPv6 criteria. [137396]

• When remarking is enabled, remarking occurs on :0,:*,0.* and null SAPs. Accordingly, the egress MAC filter matches that dot1p bit used for re-marking, even though the packets egressing these SAPs do not have a VLAN tag. [161648]

• On 7210 SAS-T access-uplink mode, traffic on dot1q saps can hit egress filter entry attached to “:0” or “0.*” or “*” sap on same port if dot1q traffic matches and matching entry not configured on dot1q sap. Workaround is to configure matching entry with actionor an entry with default action forward or drop on dot1q sap.[113270]

• The DHCP broadcast packets are sent to CPU even if DHCP relay is shut down on IES. It is recommended to delete configuration instead of keeping shut down. [161115]

• IP packets that need fragmentation are not forwarded. However, if the ARP is not resolvedfor the next-hop, only the first packet is fragmented and sent out as soon as the ARP is resolved. Only CPU-generated packets are fragmented. [76353]

• When all the member ports of a LAG are removed and added back, the stats for a SAP onthat LAG, belonging to a VPLS or an Epipe service, is reset to zero [73439]

• With a slope policy, queue depths for queues 1 to 7 for a port do not get limited to maxaverage when the scheduler is in strict mode. [85063]

• IGMP packets sent out of a SAP are not accounted in SAP egress statistics. If they are received from a peer and forwarded out of a SAP, they are accounted. [88332]

• When SSM clock quality selection is enabled, clock references are selected based on cloquality if revertive mode is configured. [111524]

• A filter entry action value configured as action should force the filter to pick up the defaultaction configured for the filter. This does not work. It is recommended to explicitly configure the action for each filter entry. [76620]

• If an ongoing FTP is terminated, the console and Telnet become unresponsive for a duration depending on the size of the file being transferred. [76734, 74294]

• The ping ip-address detail command should report the interface on which the ping reply was received. This information does not display in the output. [76887]

• When SAP in the parent MVPLS instance goes into STP blocked state, the associated SAin the child VPLS instance is shut down. This prevents any packets from being generated ithe host path. In 7210, CCM-s are hardware generated and hence the CCM state m/c workproperly. However, the LB-s and LT-s, which are generated and processed in software, stops working.[109722]

• When the show service fdb-mac command is executed through the console while the MDA is initializing (and when traffic is coming into the box), a software crash could occur. To avoid this anomaly, wait until the MDA is initialized and the ports are up before issuing thcommand. [74051]

• When a 10Gig port is congested, a small amount of excess traffic is sent out of the lower priority queues. The amount of excess traffic depends on the packet sizes. [89963, 8909489095]

• SNMP operations on some unsupported SNMP MIBs might succeed.

• There is currently no show command to display the current values of password hash settings. [32747]

• Packets larger than port MTU are learned and are accounted for by rate limiters. However,they are dropped as expected. [73497]

• When the password aging option is enabled, the reference time is the time of the last bootnot the current time. The password expiry will also be reset on every reboot. [64581]

• The number of files in the root directory is limited to 100. As a possible workaround, creaa directory in the root directory to use to save/store files. [75227]

• Quick insert and removal of USB may report flash-device failure, allow 15-30sec settlingtime to avoid these flash-device-false failure messages.

• A port LED may glow if a 1Gig fiber SFP is inserted (without connecting a cable) with 100Mbps speed configured. (Note: 100Mbps mode is not supported for 1Gig Fiber SFPs excepting dual-rate fiber SFPs and copper SFPs). [85620]



- e

• When 1G fiber SFPs are configured with a 100Mbps speed may result in un-predictable behavior. Do not set the speed to 100Mbps for 1G fiber SFPs. [81948]

• It is recommended to shutdown USB using CLI “file shutdown uf1” before USB is physically removed from the system. If removed without shutdown, following error messages may appear.CONSOLE:PLATFORM:UMASS_BBB_Send_Command Bulk Transfer Failed UTC CRITICAL: LOGGER #2002 Base A:PLATFORM:UNUSUAL_ERROR

• After 497 days, system up-time will wrap around due to the standard RFC 1213 MIB-II 32-bit limit.

• 7210 SAS-T access-uplink mode, Vpls service with svc-sap-type as Any/Null-star the maclearning will not happen when the packets are sent to ).* sap with the TPID not matching toQinQ-etype configured. The packets are taken for learning to the CPU but does not add thMAC to the fdb-table. [145962]

• 7210 SAS-T access-uplink mode when port egress is mirror source , mirrored traffic would contain additional service internal tag.

• 7210 SAS-T access-uplink mode in case of dot1q mirror destination, when sap ingress is mirror source and single priority tagged packet is mirrored, mirrored packet would not contain priority tag.

• All R-VPLS ies interfaces by default chassis mac is assigned, different mac can be configured using CLI “interface <intf-name> mac”.[139425]

• R-VPLS service not supported with *.* Saps. [140881]

• For R-VPLS service, mac address resolved by ARP is also learnt in L2 FDB table; hence ARP ages out upon FDB entry age out.

• In R-VPLS operational IP MTU is set to least of participating SAP’s MTU. SAP MTU is Port MTU – DLC header, wherein DLC header is 14 Bytes for NULL port, 18 Bytes for dot1q port and 22 Bytes for qinq port. [141391]

• 7210 SAS-T access-uplink mode, Multicast data packets with ttl=1 are not forwarded in service when MVR is configured. [143559]

• CLI “file dir” does not start to list when number files are more than 700+ files on flash cf1

• When a SAP has UP MEP configured on it, the CFM frames would use the forwarding pathof the service. This causes the “Ingress Stats” of SAP Statistics to increment when UP MEPsends packets. These packets are also counted in “Ingress Drop Stats”, if SAP’s “statistics ingress counter-mode” set to default that is, “in-out-profile-count”. [141370]

• STP BPDUs received on uplink sap hits the unicast meter instead of multi-point meter.[128453]

• Ethernet ports that use dual-rate fiber SFPs cannot participate in a Synchronous Ethernet Network.

• Applying the command "debug sync-if-timing" on a second qualified reference has no effect.

• SyncE Reference switch is based on LOS and not based on signal degradation.

• 7210 SAS-T does not display the remote MEP's MAC address in the display output of theCLI show command "show eth-cfm mep mep-id domain md-id association (ma-id) all-remote-mepids"

• The show eth-cfm mep mep-id domain md-id association ma-id command will not display Last CCM Rx-Time, Last CCM Seq Number, CCM Tx Count.

• ETH-CFM CCM Sequence Check for out-of-sequence CCMs and Last CCM Sequence Number tracking is not done for received CCMs.

• ETH-CFM CCMs with incorrect DMAC are not dropped by hardware.

• ETH-CFM CCMs transmitted will always have the Sequence Number as zero.

• ETH-CFM CCMs with invalid Data TLV-s, Invalid Port/Interface TLV-s do not cause CCM Errors

• On access ports, protocol packets of EFM, LACP, Dot1x, and DWL are counted as part ofSAP statistics if NULL SAP, Dot1q Explicit NULL SAP, or Dot1q Default SAP is configured on an access port. [95361]

• In 7210 SAS-T, a null SAP allows 4 bytes more than the port MTU for tagged traffic (excluding FCS); a dot1q SAP allows 8 bytes more than the port MTU for tagged traffic (excluding FCS); and a dot1q-star SAP allows 4 bytes more than the port MTU for un-tagged traffic and 8 bytes more than the port MTU for tagged traffic (excluding FCS).

• If single -tagged multicast packets arrive on a null SAP belonging to a VPLS service with IGMP snooping enabled, they are forwarded based on the MFIB if the entry is present, elsethey are dropped.

The same is applicable for double-tagged multicast packets arriving on a Dot1q SAP. [87551]

• Dual rate SFPs (3HE04116AA and 3HE04117AA) connected to GigE SFP require autonegotiation to be disabled to operate in 1G mode. [78737]

• SAP ingress meters (counters) are incremented for packets dropped by a filter on that SAP[70878]

• If the system IP address is not configured, RADIUS user authentication will not be attempted for in-band RADIUS servers unless a source address entry for RADIUS exists.

• SNMP access cannot be authorized for users by the RADIUS server. RADIUS can be usedto authorize access to a user by FTP, console, or both.

• If the first server in the list cannot find a user the server will reject the authentication attempt. In this case, the 7210 node does not query the next server in the RADIUS server list and denies access. If multiple RADIUS servers are used, the software assumes they ahave the same user database.

• In an Epipe service, traffic is not switched if the source MAC is a multicast or broadcast address [71437]

• A service configured with 'svc-type any" and null-sap to null-sap allows packets up to 151including 4 byte FCS if port MTU is default value 1514. Workaround is to increase port MTU from default value of 1514. [116239]

• 7210 SAS-T accepts packets with sizes exceeding the port MTU by 4 bytes as listed in below scenarios if egress port has proper MTU to transmit these extra bytes.

- 1522 byte (includes 4 byte FCS) single vlan tagged or 1526 byte (includes 4 byte FCS) double vlan tagged packets received on null sap is forwarded where ingress is null port and egress is dot1q/qinq port.

- 1526 byte (includes 4 byte FCS) double vlan tagged packet received on dot1q sap isforwarded where ingress port is dot1q and egress is qinq port.

k.

• A MAC will not age out as long as STP BPDUs from that source are received, although data traffic is not present. [71658]

• If the TACACS+ start-stop parameter option is enabled for accounting, every command will result with two commands in the accounting log.

• If TACACS+ is first in the authentication order and a TACACS+ server is reachable, the user will be authenticated for access. If the user is authenticated, the user can access theconsole and has the rights assigned to the default TACACS+ authenticated user template config>system>security>user-template tacplus_default. Unlike RADIUS, TACACS+ does not have fine granularity for authorization to define if the user has only console or FTP access. The 7210 SAS OS supports a default template for all TACACS+ authenticated users.

• If TACACS+ is first in the authentication order and the TACACS+ server is not reachable, the authorization for console access for the user is checked against the user’s local or RADIUS profile if configured. If the user is not authorized in the local/RADIUS profile, the user is not allowed to access the box.

• Note that inconsistencies can arise depending on certain combinations of local, RADIUS and TACACS+ configurations. For example, if the local profile restricts the user to only FTP access, the authentication order is TACACS+ before local, the TACACS+ server is up and the TACACS+ default user template allows console access, an authenticated TACACS+ user will be able to log into the console using the default user template becausTACACS+ does not provide granularity in terms of granting FTP or console access. If the TACACS+ server is down, the user will be denied access to the console as the local profile only authorizes FTP access. [39392]

• If a source-address entry is configured for in-band RADIUS servers, the source address (Iaddress) is used as the NAS IP address, otherwise the IP address of the system interface iused.

• default.cfg is a file name reserved by the system. Do not create a file with this name in the root directory. [76972]

• In an ingress MAC filter policy, the etype and frame-type match criteria do not match packet fields in those packets received with more than one VLAN tag. [72839]

• MACs that are already learned do not age out after a filter is added to drop packets from those MACs. [73370]

• Packets with CRC errors are accounted for in the ingress meter calculations. [80966]

• Packets discarded as the result of a discard-unknown-source and discard-unknown configuration are accounted for in the ingress meter calculations. [84842]

• Meter buckets are re-initialized when the rate value is modified. Rate values are modifiedby explicitly changing the rate values using the appropriate CLI command or by changingthe adaptation rule. [84395]

• Ethernet ports that use copper SFPs cannot participate in a Synchronous Ethernet Networ

KNOWN ISSUES

The following are specific technical issues and limitations that exist in Release 6.0R8 of 721SAS-T OS. The topics are arranged alphabetically.

NOTE:

• Issues marked as MI might have had a minor impact but did not disturb network traffic.

• Issues marked as MA might have had a major impact on the network and might have disturbed traffic.

• Issues marked as CR were critical and might have had a significant amount of impact on the network.

ACL S • Time of day policies cannot be combined with IPv6 ACLs [136880-MI]

CLI • There are some unsupported CLI and CLI options displayed in the CLI command set.

• Some of the show, monitor, and tools CLI command output displays unsupported fields andmodules.

• The output of the tools dump command is not aligned properly when issued from a Telnet session. [76876-MI]

• In the Telnet session, the output for tools dump is not properly displayed. [80661-MI]

IP • SNMP query of the vRtrActiveArpEntries object does not return the correct value. The CLIreports the correct number of ARP entries. [80788-MI]

LAG • In an LAG, if port is down due no LACP packets received from other end then, the unlearned traffic sent on other active ports of lag is also flooded on the operating down port.

MANAGEMENT • Ping check during autoinit using CLI "bof ping <ip-address>" does not work.

• System allows to remove a trap-target from a snmp-trap-group even if that particular trap-target is configured under “snmp-dying-gasp”. Execution of such saved configuration errors out. [182398-MI]

• SNMP dying gasp trap command should be re-configured when user makes changes to th“notify-community” and it’s associated security, access control parameters. [125539-MI].

• SNMP dying gasp trap for snmpv1 trap server is not supported. [125543-MI]

• SNMP dying gasp trap packet's source ip is set to the system IP address. [15552-MI]

• If a source-address is configured for NTP, and if the system is rebooted with an older timeset (using admin set-time), NTP takes a few iterations to synchronize for the first time. [86897-MI]

• SNMP operations on some unsupported SNMP MIBs might succeed.



t

y

• The CLI allows the user to specify a TFTP location for the destination for the admin saveand admin debug-save commands which will overwrite any existing file of the specified name. [18554-MI]

• SNMP walk of vRtrConfEntry shows the vpls-management and management instance as active even though these are not currently supported. [76832-MI]

• SNMP query of the following operational rates does not return the correct values. The value returned is 0. CLI reports correct operational values. [76853-MI].

- tAccessEgressQueueOperPIR

- tAccessEgressQueueOperCIR

MIRROR • Ingress QoS policies applied for forwarded traffic will also be reflected on its mirrored traffic, if mirror destination is a null SAP. [73951-MI]

OAM • The Y.1564 testhead, when configured to use internal-loopback-ports, latency will not be computed when frame size is greater than 9000 bytes. Same test works fine with front panel port used as loopback ports. [177164-MI]

• "vlan 0" for CLI "configure eth-cfm domain < > association < > bridge-identifier < >" is not supported. [169536-MI]

• “send-ais-on-port-down” is not supported in 6.0R3. [160333]

• It is not recommended to use fault-propagation when the service entities (for example, SAPand SDP binding) are configured on a LAG. A LAG flap can result in CFM defect being raised which inturn results in a false fault propagation event. This issue is seen only whenCCM timers of less than 10 seconds are in use. This configuration is not blocked in CLI but it is highly recommended that users do not use fault propagation with LAG when using CCM timers of less than 10 seconds. [150233-MA]

• Eth-CFM convergence fails when llf is enabled on the LAG SAP and Lag shut and no-shuis done, or box is admin saved and rebooted.

Workaround: Remove and add back MEPs. [116513-MA]

• On a given SAP in any service, in order to use Y.1731 2-DM, it is recommended to configure only one Y.1731 MEP, otherwise, 2-DM may not work properly. Except 2-DM, other functionalities are not affected even if there are multiple MEP's. [118015-MI]

• ETH-CFM defect is not reported on booting the 7210 SAS with a configuration that has theETH-CFM session over a LAG with no member ports. [100813-MI]

QOS • During heavy congestion in the system such that shared buffers are utilized completely andschedular mode is strict, line rate traffic may not be achieved for all sizes of packet. [164543]

• Overwriting on to an existing slope-policy does not work. That is, copying one slope policyto another existing one does not overwrite. Workaround is to delete the second slope policand then copy. [163000]

• Inner tag dot1p not getting remarked when egress is qinq sap and ingress is dot1q sap. [163616]

• tAccessEgressRemarkType mib object is not supported. [160238-MI]



r

• telnet, ftp, ssh, radius, and tacplus are egressing on NC queue. [162022-MI]

• Ingress qos resources are not getting released when the ingress qos policy is removed fromthe sap with tod-suite configured. [141896-MA].

• Access-Egress policy enabled with DSCP remarking, remarks DSCP bits in data packets egressing out of L2 SAPs (VPLS/Epipe/I-VPLS/B-VPLS). It is recommended not to enable DSCP remark for ports carrying L2 SAPs. [121134-MI]

• Operational values for some user configured values of ERL rate are incorrect in the show pool output of a port. [90549-MI]

• When remarking is enabled on access egress for a Dot1q port, the Dot1p bits in the customer tags get remarked when the traffic is sent out of a Dot1q default SAP or a NULL SAP. [86818-MI]Workaround: In the case of a NULL SAP, remarking can be disabled to preserve the Dot1pbits.

• The maximum entry-id value for the IP/MAC-criteria in the SAP ingress policy context is restricted to 63 although the CLI allows up to 64. Entry-id 64 should not be specified. [76790/76964-MI]

• Ingress qos resources are not getting released when the ingress qos policy is removed fromthe SAP with “tod-suite” configured. [141896-MA].

RADIUS • In defining RADIUS Vendor Specific Attributes (VSAs), the TiMetra-Default-Action parameter is required even if the TiMetra-Cmd VSA is not used. [13449]

SERVICES • In 7210 SAS 6.0R3 release, number of IGMP Groups supported is 1000.[162731]

• When a time-range is expected to be active, a delay of up to 8 seconds can be expected foan associated filter policy on either ingress or egress. [161652-MI]

• Default sap (:* sap) does not participate in igmp-snooping process. Igmp query sent on default sap is flooded to all the saps and not learned in MFIB. Igmp report sent on the default sap is dropped if there is no entry in the MFIB and follows MFIB if there are entries. Registered Multicast Data packets sent on default sap follows MFIB.

Un-Registered Multicast Data packets sent on default sap gets flooded in the service. [109045-MI]

• Dot1p priority is not preserved for RSTP packets forwarded by the node (for example doubly tagged STP packets received on a SAP). The dot1p is remarked to 7. Additionally, these packets are not matched against egress filter policies. [71855/75921-MI]

• Changing the fdb-table-size on multiple services simultaneously (for example, by a script) may affect MAC learning in some services. [82362-MI]

STATISTICS/ACCOUNTING

• Attaching accounting-policy on “Uplink SAP” is not supported and should not be configured, however CLI commands exist. [111897-MI]

STP • If a large number of MAC addresses exists in the VPLS FDB and the entire FDB is flushedand relearned, there may be a period of when RSTP BPDUs are not sent. A partial workaround is to configure fdb-table-size limits. [40532-MI]

SYSTEM • When performed "file dir" on empty drive (cf1 or uf1), shows "MINOR: CLI File Not Found "uf1:"." [178197-MI]

• The 7210 SAS-T PoE : Class1 PD is detected as Class4 after PoE port shut or noshut or noPoE/PoE plus or reboot. [164882]

• 7210 SAS-T PoE: PSE is not denying power even after PDs drawing maximum threshold of 60W power. [165416]

• During AutoInit using DHCP, it is recommended to store proper bof, config files in definedlocation. In lab scenario, it is observed that, through DHCP, if 7210 SAS fetches the ip address, but bof or config file is not stored in a defined location, after several DHCP request or replies, DHCP starts failing. A reboot of 7210 SAS is required to recover from DHCP failures. [131915-MI]

• 10Gig alarms, “no-frame-lock” and “high-ber”, are not supported on the 7210 although they are configurable.-MI

• The configure port port-id ethernet report-alarm command option no-frame-lock or high-ber are allowed to be configured but they are not supported. This command is applicable only for 10G ports-MI.

• In certain scenarios (such as Cu SFP connected to Fixed Cu), the show port command doenot display the MDI/MDX value as expected. Functionality is not affected. [76765-MI]

• In certain scenarios, traffic drops are seen during source learning when copper ports are operating in half duplex modes. Once learned, there are no other observed drops. [75875-MI]

• The system time MIB object stiDateAndTime is the UTC time and should not include the time zone offset in SNMP get and set requests. [66553-MI]

• During auto-config, if a DHCP relay packet for an unrelated DHCP session is received bythe system, the system may be non-responsive. [76811-MA].

• Control protocols may flap when the file copy command is initiated, using FTP, from the system if the specified FTP server is not reachable. This happens under loaded CPU conditions. Before initiating the file copy command using FTP, verify that the FTP server reachable. [76566-MI].

• The system saves core dumps at the URL specified in the BOF, while coming up. Specifying a remote location as a core file destination has two issues.

- If a remote URL is specified, and if the uplinkA cannot be brought up, saving the cordump may not succeed, even if uplinkB is up.

- If uplinkA’s BOF is configured to use DHCP, the IP address acquired by DHCP is noreleased by the system after saving the core file.

Thus, it is recommended to configure the core file destination to be the local flash (cf1). [76764, 76736-MI].

• For dual rate fiber SFPs to operate successfully, both sides should be configured with the correct speeds. [82194-MI]

• When using 100FX SFPs, autonegotiation should be disabled. [99132-MI]
