Chapter 2New Features and Enhancements

New Features and EnhancementsThis chapter describes the features and enhancements introduced in this release.

ARM

Uplink MU-MIMO TransmissionAruba Instant 8.8.0.0 supports the uplink MU-MIMO transmission of 802.11ax protocol. Prior to Instant8.8.0.0, MU-MIMO allowed to send data frames from access points to clients. Now, the uplink MU-MIMOtransmission allows to send data frames from clients to APs. It also helps in achieving throughput gainswhen applications need to upload large amount of data. It also enables themultiple spatially separatedclients to access the channel at the same time and it is also useful in scenarios where stations have limitednumber of antennas. The uplink MU MIMO transmission is supported only in 5 GHz band. Only AP-535 andAP-555 access points support uplink MU MIMO transmission.

Support for Zero-Wait DFSDynamic Frequency Selection (DFS), amandate for radio systems operating in the 5 GHz band to identifyand avoid interferencewith Radar systems now supports the zero-wait feature. When an 802.11 radiodetects radar, it vacates its channel and switches to another channel. Thismight result in a oneminuteoutage. Starting fromAruba Instant 8.8.0.0, the zero-wait DFS feature provides seamless change ofchannels and avoids the oneminute outage. Hence, stations do not lose its connectivity when an APmovesto a DFS channel. This feature is enabled by default.

Authentication

Configuring a Timeout Duration for 802.1X AuthenticationA new CLI command ap1x-timeout is added to configure a timeout duration for 802.1X authenticationwhen the AP is used as a supplicant for 802.1X authentication

Configuring Ageout Time for PMK Cache EntriesA new setting, delete-pmkcache, is introduced in theWLAN SSID profile to delete client information in thePMK cachemaintained for fast roaming. Configuring this setting deletes client information in the PMK cacheimmediately after a client disconnects or times out from the network as opposed to the default ageout timeof 8 hours. This is configured using the CLI.

Support for New CoA TypeAruba Instant supports a new CoA type for the radius attributeAcct-Session-Id.

Support for New Diffie-Hellman Groups for OWEAruba Instant supports theDiffie-Hellman Groups 20 and 21 for Enhanced Open security.

Central

Automatic Installation of DRT UpdatesInstant APsmanaged by Central can now automatically download and install the latest DRT file available onActivate. TheDRT file includes the details of approved regulatory certifications and allowed RF transmissions(channels, EIRP, and so on..) for an AP at any geographical region or country.

Enhancements to Telemetry Information Sent to CentralThe AP now includes the following information in the telemetry data sent to Aruba Central:

n Status of uplink interfacesn Health of uplink interfacesn Uplink failover events with the reason for failover

Support for Green APsInstant APs supports Aruba Central's green AP featurewhich puts an AP into deep sleepmodewhen theservices required from the AP isminimal to nil. This helps in reducing the power used by the AP andconserves energy whenever possible. When the AP's service is required, Aruba Central wakes the AP fromdeep sleepmode through an active AP in the same subnet.

Datapath

Enabling SFTP TransfersAruba Instant now supports transfer of files using SFTP from the server to an AP. A new CLI command isintroduced to support downloading and uploading of a configuration file using SFTP.

The following command restores the configuration through SFTP:(Instant AP)# copy sftp <addr> <file> <username> system config

The following command is used to backup the configuration through SFTP:(Instant AP)# copy config sftp <addr> <file> <username>

Parameter Description

<addr> Denotes the IP address of remote sftp server.

<file> Denotes the configuration file’s absolute path of the remoteserver.

<username> Denotes the user name used to establish an ssh connection to theremote server.

Reboot the AP for the configuration changes to take effect.

Firewall

Increase in the Data Rate Range for Bandwidth Limit Contracts andApplication Throttling

Page 9: Aruba Instant 8.8.0.0 Release Notes

Chapter 7Upgrading an Instant AP

Upgrading an Instant APThis chapter describes the Instant software upgrade procedures and the different methods for upgradingthe image on the Instant AP.

While upgrading anInstant AP, you can use the image check feature to allow the Instant AP to find new softwareimage versions available on a cloud-based image server hosted andmaintained by Aruba. The location of theimage server is fixed and cannot be changed by the user. The image server is loaded with the latest versions ofthe Instant software.

Topics in this chapter include:

n Upgrading an Instant AP and Image Server on page 26n Upgrading an Instant AP Using the Automatic Image Check on page 28n Upgrading to a New VersionManually Using theWebUIn Upgrading an Instant AP ImageUsing CLI on page 31n Upgrade from Instant 6.4.x.x-4.2.x.x to Instant 8.8.0.x on page 32

Upgrading an Instant AP and Image ServerInstant supportsmixed Instant AP class Instant deployment with all Instant APs as part of the same virtualcontroller cluster.

Image Management Using AirWaveIf themulti-class Instant AP network ismanaged by AirWave, image upgrades can only be done through theAirWaveWebUI. The Instant AP images for different classesmust be uploaded on the AMP server. If newInstant APs joining the network need to synchronize their softwarewith the version running on the virtualcontroller, and if the new Instant AP belongs to a different class, the image file for the new Instant AP isprovided by AirWave. If AirWave does not have the appropriate image file, the new Instant AP will not beable to join the network.

The virtual controller communicates with the AirWave server if AirWave is configured. If AirWave is not configuredon the Instant AP, the image is requested from the Image server.

Image Management Using Cloud ServerIf themulti-class Instant AP network is not managed by AirWave, image upgrades can be done through theCloud-Based Image Check feature. If a new Instant AP joining the network needs to synchronize its softwareversion with the version on the virtual controller and if the new Instant AP belongs to a different class, theimage file for the new Instant AP is provided by the cloud server.

Configuring HTTP Proxy on an Instant APIf your network requires a proxy server for Internet access, ensure that you configure theHTTP proxy on theInstant AP to download the image from the cloud server. TheUsername and Password configuration is

Aruba Instant 8.8.0.0 | Release Notes 26

Page 27: Aruba Instant 8.8.0.0 Release Notes

27 | Upgrading an Instant AP Aruba Instant 8.8.0.0 | Release Notes

supported only for cloud services. After setting up theHTTP proxy settings, the Instant AP connects to theActivate server, AMP, Central, OpenDNS, or web content classification server through a secure HTTPconnection. The proxy server can also be configured and used for cloud services. You can also exemptcertain applications fromusing theHTTP proxy (configured on an Instant AP) by providing their host nameor IP address under exceptions.

In the Old WebUITo configure theHTTP proxy settings:

1. Navigate to System > Proxy. The Proxy configuration window is displayed.2. Enter theHTTP proxy server IP address in the Server text box.3. Enter the port number in the Port text box.4. If you want to set an authentication username and password for the proxy server, select the Proxy

requires authentication checkbox.5. Enter a username in theUsername text box.6. Enter a password in the Password text box.7. If you do not want theHTTP proxy to be applied for a particular host, clickNew to enter that IP

address or domain name of that host in the Exceptions section.

In the New WebUITo configure theHTTP proxy settings:

1. Navigate to Configuration > System > Proxy.2. Enter theHTTP proxy server IP address in theAuth Server text box.3. Enter the port number in the Port text box.4. If you want to set an authentication username and password for the proxy server, enable the Proxy

requires authentication toggle switch.5. Enter a username in theUsername text box.6. Enter a password in the Password text box.7. If you do not want theHTTP proxy to be applied for a particular host, click + to enter that IP address

or domain name of that host in the Exceptions section.8. Click Save.

In the CLITo configure theHTTP proxy settings:

(Instant AP)(config)# proxy server 192.0.2.1 8080 example1 user123(Instant AP)(config)# proxy exception 192.0.2.2(Instant AP)(config)# end(Instant AP)# commit apply

HTTP Proxy Support through Zero Touch ProvisioningInstant APs experience issues when connecting to AirWave, Central, or Activate through theHTTP proxyserver which requires a user name and password. The ideal way to provide seamless connectivity for thesecloud platforms is to supply the proxy information to the Instant AP through aDHCP server.

Starting with Aruba Instant 8.4.0.0, besides being able to authenticate to theHTTP proxy server, the factorydefault Instant APs can also communicatewith the server through aHTTP proxy server DHCP which doesnot require authentication.

Page 28: Aruba Instant 8.8.0.0 Release Notes

Aruba Instant 8.8.0.0 | Release Notes Upgrading an Instant AP | 28

In order for the factory default Instant AP to automatically discover the proxy server, you need to configuretheHTTP proxy information in theDHCP server option. The Instant AP will receive the proxy informationand store it in a temporary file.

To retrieve the port and the proxy server information, you need to first configure theDHCP option 60 toArubaInstantAP as shown below:

(Instant AP)(config)# ip dhcp <profile_name>(Instant AP)("IP DHCP profile-name")# option 60 ArubaInstantAP

Secondly, use the following command to configure the proxy server:

(Instant AP)(config)# proxy server <host> <port> [<username> <password>]

Use the text string option 148 text server=host_ip,port=PORT,username=USERNAME,password=PASSWORD to retrieve the details of the proxy server.

Rolling Upgrade on Instant APs with AirWaveStarting fromAruba Instant 8.4.0.0, Rolling Upgrade for Instant APs in standalonemode is supported withAirWave. The upgrade is orchestrated through NMS and allows the Instant APs deployed in standalonemode to be sequentially upgraded such that the APs upgrade and reboot one at a time. With RollingUpgrade, the impact of upgrading a site is reduced to a single AP at any given point in time. This enhancesthe overall availability of thewireless network. Formore information, see AirWave 8.2.8.2 Instant DeploymentGuide and AirWave 8.2.8.2 Release Notes.

Upgrading an Instant AP Using the Automatic Image CheckYou can upgrade an Instant AP by using the Automatic Image Check feature. The automatic image checksare performed once, as soon as the Instant AP boots up and every week thereafter.
