What’s New in Release 2.4.1.0 These release notes describe new features in ArubaOS 2.4.1.
Issues and Limitations Fixed in this Release The following issues and limitations from 2.4.0.0 have been fixed in this release: Authentication The user entry created on the Home Agent (HA) does not display the correct Location, Roaming, ESSID/BSSID/Phy values. However, this is a displayonly issue and the correct values are being enforced. (6151) If trim-fqdn is enabled for 802.1x server, the domainname portion for the FQDN is still passed to the RADIUS server by the client internal EAP module.
WEP/TKIP traffic no longer experiences memory contention issues and thus no longer freezes up. (6842) SNMP A trap is now generated when the switch role is changed. (8262) Soft AP The problem with in-band destined traffic occasionally being routed through the out-of-band (mgmt) interface has been fixed. (6629) The max-client limit is no longer being ignored. (8218) The Network Summary now correctly reports AP status. (8117). AP 60s no longer stop sending beacons while configuring virtual APs.
(MTU) on these Access Points to 1500 bytes. Do this by entering (from enable mode) under the AP location: ap location 0.0.0 mtu 1500 write memory Aruba only supports directly connecting Aruba Mobility Controllers with a cross-over cable. Connecting Aruba Mobility Controllers with straight-through cables is not recommended. Using the proper (cross-over) cable, ports on both sides of the connection can be configured to auto-negotiate or can be hard coded as long as they match.
While moving a station, if 802.1x authentication is delayed, the show user global-user-map command output is not displayed correctly. (6557) Wired clients who fail authentication are blacklisted, but they can still try to login. (6802) Session mirroring does not update for sessions that are already up. (6829) All PPTP connections to Aruba (or any PPTP server) for users with Windows XP Service Pack 2 firewall enabled, will experience a one minute wait before being able to reconnect.
After a role-based VLAN is disabled, the 802.1x client will not have connectivity for a few minutes. (7892) Monitoring > Switch Summary may not display the correct total of clients and switches. The WLAN client summary may be smaller than the total of client entries because the per-switch display includes additional entries – which are not shown in the global user list. (7904) When you upload a license certificate, fpweb will restart. This is normal.
7 No SNMP traps are generated when software feature licenses are added, deleted, or expire. Syslog messages, however do report these events.(7450) Sygate SMS does not return MPPE keys when user authentication fails and host authentication is passed. (7736) When Sygate Virtual Desktop check is enabled, the first check will always fails and the subsequent check will pass.
Occasionally the SNMP community does not appear in the WebUI until the page is refreshed. (7867) On the WebUI, navigating to AP >Status > Client may produce an error. (8285) Occasionally, when all the parameters are configured in the LDAP server page of the WebUI, only some of the configured parameters are applied. (8023) ESI may report incorrect servers in the datapath when servers were moved around within a group.
For information on upgrading to, or downgrading from, 2.4.1.0, refer to Installing ArubaOS 2.4.1.0—Prerequisites. Before you Change your Switch’s Image All Aruba Mobility Controllers store critical configuration data on an onboard Compact Flash memory module.
If an Aruba switch encounters a bug where it needs to write a core file, it will not be able to do so if the file system is full and critical troubleshooting information will be lost. Powering the System Down or Power Cycling the System Compact Flash devices can be corrupted if power is lost during a write event (for example. write mem). To reduce the exposure of Compact Flash to corruption, be sure to follow these procedures: For AirOS release 2.
Upgrading to ArubaOS 2.4.1.0 The Aruba ArubaOS software can be upgraded as new releases become available. The following steps abbreviate the detailed procedures located in the Aruba ArubaOS 2.4 User’s Guide.
(aruba) # copy flash: default.cfg tftp: Note— A valid IP route must exist between the TFTP server and the Mobility Controller. Also required, a placeholder file with the destination filename and proper write permissions must exist on the TFTP server prior to executing the copy command. Backup your current WMS and local user databases.

Upgrading Multi-Switch Networks In a multi-switch network (one with two or more Mobility Controllers), special care must be taken to upgrade all switches in the proper sequence, based on the switch type (master or local). Be sure to back up all switches being upgraded. Make sure you have at least 10MB free flash. Back up the WMS database and TFTP it off the switch. Remove all unnecessary saved files from flash.
Upgrade the Local switches to the new code. Do not reboot the Local switches yet. From the Master CLI, enter apboot location 0.0.0 Now reboot the Local switches. The APs should now have the new version of ArubaOS since they were rebooted and not failed over through VRRP. Reverting to AirOS 2.X.X.X If necessary, you can to return to your previous version of AirOS 2.X.X.X software after upgrading to a newer version. Be sure to back up your switch before reverting the OS.

Boot to your default.cfg file. # boot config default.cfg Replace the current WMS database file with your backup.
Troubleshooting If the switch gets into trouble (for example, insufficient – less than 10MB – flash space), do the following: Disconnect the link to the APs. Remove all unnecessary files from flash, including the db_dump.sql type files. Remove any crash files. Import the old wms DB file and reboot. Reconnect the link for the APs.
