1. Introduction

1.1 NW Switch Module Diagram

Two NW Switch modules are installed in a chassis. Each NW Switch module consists of external interfaces (40Gbps QSFP+ x8ports) and internal interfaces (for each CPU Slot 10Gbps x1).

The figure below shows the NW Switch Module Diagram.

The number 1 to 79, “mgmt” and “internal” show the physical ports. For more details, please refer to the next page.

1. Introduction


1.2 Interface Number on CLI

This table shows the description of each interface to select on CLI.

Interface Connected to Description

Port1-Port44 Module Slots • Server Module LAN • 10G Expansion Module LAN

The Interface number corresponds to the Slot ID.

Port45-Port76 QSFP+ Modules For 40G mode, the lowest number of each port represents the interface. (Port45, 49, 53, 57, 61, 65, 69, 73)

Port77 RJ45 Port Management LAN Port78 Interconnect interface to the

adjacent NW Switch module Disabled as default.

Port79 CSC - mgmt CPU for LAN-Switch NW Switch Module management Interface lo - For internal use internal - For internal use

1.3 Initial VLAN Configuration

To separate the management LAN and data LAN, the interfaces are configured as follows by LAN switch software.

Interface VLAN Configuration

Port1-Port44 VLAN1 (untagged) VLAN4092 (tagged)

Port45-Port76 LAN1 (untagged) Internal VLAN4092 (untagged) Port78 VLAN1 (untagged)

User can access to BMC from the management LAN only because the BMC is configured as VLAN4092.

The modules below can be accessed from management LAN (Port77).

1. Introduction


1.4 Connecting to the Switch Console Port

To connect to the switch CLI using the console port, configure the serial port of terminal with the following settings.

Baud rate: 115200

Data bits: 8

Stop bits: 1

Parity: none

Flow control: none

1.5 Accessing the CLI

To login to the switch CLI, login at the prompt as admin/admin (default username and password) using serial console, telnet or ssh.

Linux 3.2.40 (Switch) (0) login: admin Password: ZebOS-XP version 1.2.0 IPIRouter 11/20/15 18:06:09 Switch>

1.6 Default Account

To login to the LAN-Switch CLI, use an account below.

Username： admin

Password： admin

2. System Configuration



2.1 Saving a system configuration

You can save the current configuration using the following command.

Switch>enable Switch#write Building configuration... [OK]

Reboot or shutdown the NW Switch Module without saving will discard the changes.

2.2 Restore initial configuration

To restore the default configuration, use the following commands.

Switch>enable Switch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#system restore default-config This task requires reboot system, do you want to continue? (y/n):y

Note: This command will automatically reboot the NW Switch Module.

2.3 Exporting Switch Configuration

You can export saved configuration from the NW Switch Module to an external server by TFTP using the following commands. (Save the configuration (execute “write”) before exporting the configuration.)

Example: To export configuration file named “startup-config” to TFTP server (IP address 192.168.7.254),

Switch>enable Switch#copy startup-config tftp Enter IP:192.168.7.254 Enter port [69]:69 Enter filename:startup-config

* User can also use the command below

copy startup-config tftp tftp://192.168.7.254/startup-config



2.4 Importing Switch Configuration

You can import a previously exported configuration file from an external server by TFTP using the following commands.

Switch#copy tftp startup-config Enter IP:192.168.7.254 Enter port [69]:69 Enter filename: startup-config Copy Success...

You need to reboot the NW Switch Module (“reload” command) to enable the new configuration.

* User can also use the command below

copy tftp tftp://192.168.7.254/startup-config startup-config

2.5 Show IP Address

To show the management IP address,

Switch>show interface mgmt Interface mgmt Scope: both Hardware is Management Ethernet Current HW addr: 0011.2233.44ff Physical:0011.2233.44ff Logical:(not set) index 2 metric 1 mtu 1500 duplex-full no switchport <UP,BROADCAST,RUNNING,ALLMULTI,MULTICAST> VRF Binding: Not bound Bandwidth 96k IPV4 DHCP client is enabled <client-id=mgmt, hostname=n/a>. IPV6 DHCP IA-NA client is enabled. inet 192.168.1.177/21 broadcast 192.168.7.255 inet6 fe80::211:22ff:fe33:44ff/64 input packets 00, bytes 00, multicast packets 00 broadcast packets 00 FCS error 00 UndersizeErrors 00 OverSizeErrors 00 output packets 00, bytes 00, multicast packets 00 broadcast packets 00

If NTP is unused, configure the clock manually using clock command. Shutdown or reboot of the switch resets the system clock.

Switch>enable Switch#configure terminal Switch(config)#no ntp enable Switch(config)#exit Switch#clock set 12:00:00 1 january 2016

To show the system clock,

Switch>enable Switch#show clock 12:00:03 UTC Fri Jan 01 2016
