Cckm Timestamp Tolerance; Auto-Immune - Cisco 7925G Deployment Manual

Below are the commands to change the QBSS max threshold for each platform type.
Cisco Unified Wireless LAN Controller = config advanced 802.11b 7920VSIEConfig call-admission-limit <value>
Cisco Autonomous Access Point = dot11 phone cac-thresh <value>

CCKM Timestamp Tolerance

As of the 7.0.98.218 release, the CCKM timestamp tolerance is configurable.
In previous releases, the CCKM timestamp tolerance was set to 1000 ms and non-configurable.
The default CCKM timestamp tolerance is still set to 1000 ms in the later releases.
It is recommended to adjust the CCKM timestamp tolerance to 5000 ms to optimize the Cisco Unified Wireless IP Phone
7925G, 7925G-EX, and 7926G roaming experience.
(Cisco Controller) >config wlan security wpa akm cckm timestamp-tolerance ?
<tolerance> Allow CCKM IE time-stamp tolerance <1000 to 5000> milliseconds; Default tolerance 1000 msecs
Use the following command to configure the CCKM timestamp tolerance per Cisco recommendations.
(Cisco Controller) >config wlan security wpa akm cckm timestamp-tolerance 5000 <WLAN id >
To confirm the change, enter show wlan <WLAN id>, where the following will be displayed.

Auto-Immune

The Auto-Immune feature can optionally be enabled for protection against denial of service (DoS) attacks.
Although when this feature is enabled there can be interruptions introduced with voice over wireless LAN, therefore it is
recommended to disable the Auto-Immune feature on the Cisco Unified Wireless LAN Controller.
The Auto-Immune feature was introduced in the 4.2.176.0 release, which was enabled by default and non-configurable.
As of the 4.2.207.0, 5.2.193.0 and 6.0.182.0 releases this feature is disabled by default but can be enabled optionally.
To view the Auto-Immune configuration on the Cisco Unified Wireless LAN Controller, telnet or SSH to the controller and
enter the following command.
