Proxy Arp - Cisco 7925G Deployment Manual

If using WPA/WPA2 PSK then it is recommended to reduce the EAPOL-Key Timeout to 400 milliseconds from the default of
1000 milliseconds with EAPOL-Key Max Retries set to 4 from the default of 2.
If using WPA/WPA2, then using the default values where the EAPOL-Key Timeout is set to 1000 milliseconds and EAPOL-
Key Max Retries are set to 2 should work fine, but is still recommended to set those values to 400 and 4 respectively.
The EAPOL-Key Timeout should not exceed 1 second (1000 milliseconds).
To change the EAPOL-Key Timeout on the Cisco Unified Wireless LAN Controller, telnet or SSH to the controller and enter
the following command.
(Cisco Controller) >config advanced eap eapol-key-timeout
