Configuring Proxy ARP
To advertise the proxy ARP information element, ensure that Aironet extensions are enabled.
Ensure proxy ARP is enabled, where ARP Unicast Mode will be displayed as disabled on the Cisco Unified Wireless LAN
Controller.
Telnet or SSH to the controller and enter
“show network”
or
“show network summary”
depending on the Cisco Unified
Wireless LAN Controller version.
If ARP Unicast Mode is enabled, enter
“config network arpunicast disable”
.
As of the 5.1.151.0 release, proxy ARP is always enabled and non-configurable.
For autonomous access points, enter “
dot11 arp-cache optional”
.
Configuring TKIP Countermeasure Holdoff Time
TKIP countermeasure mode can occur if the Access Point receives two message integrity check (MIC) errors within a 60
second period. When this occurs, the Access Point will de-authenticate all TKIP clients associated to that 802.11 radio and
holdoff any clients for the countermeasure holdoff time (default = 60 seconds).
To change the TKIP countermeasure holdoff time on the Cisco Unified Wireless LAN Controller, telnet or SSH to the
controller and enter the following command:
(Cisco Controller) >config wlan security tkip hold-down <nseconds> <wlan-id>
