Hi all,

some time we have periodically dropping off the network or just periodically re-registering with call manager.

Usualy should proxy arp activated by default from release 5.x.

But if we look on 7921 site survey it indicate that proxy arp is not activated. How can we check if it's active or how we cant it to active?

In 6.0 the controller is doing proxy arp.  There is not a way to disable it.  In earlier releases you could choose proxy arp or unicast arp but unicast arp was removed from the controllers in the later versions and only proxy arp is left.

Glad to see our site survey application is being helpful.

That is definitely odd that proxy ARP is listed as not as enabled.

Believe since 5.0 and later it is enabled and not configurable.

May want to get a wlan sniff to inspect the proxy ARP IE.

We use proxy ARP to optimize battery life.

The #s in the data sheet are based on proxy ARP being enabled.
