With the IP address 10.10.139.34 was the AP able to reach the gateway.

CAPWAP AP configured with static IP will fall back to DHCP ip , if they are not able to reach the gateway with the IP configured

Thanks

Noman,

Was the AP able to reach the gateway of 10.10.139.34 with the static IP.Say if the gateway of 10.10.139.34 was 10.10.139.1, was the AP able to resolve this IP.

If looks to me you have connected the AP in wrong VLAN port and that is the reason why the AP has fallen to DHCP IP

Nikhil,

Yes the AP is reaching the gateway 10.10.139 and one more thing there are also some clients that are connected to that AP and able to access the machines on on same VLAN as well as Other VALN's present in the network.

Is the AP with the ip 10.10.139.34 having a mask of 255.255.254.0 ?

Did you try assigning static IP again to the AP

This error means the AP was not able to communicate with the WLC with assigned static IP address. When this happens the ap will fall back ti trying ti get a DHCP address.

I am trying to figure out why AP was't able to communicate with the WLC with assigned static IP address when there is no change in WLC configuration or any other parameter of Network...
