Access point AIR-LAP1141N-A-K9 is not taking IP

[surendranaths88]

Hi all, 

An access point in my organization is not taking IP address. 

From the switch If i give cdp neighbor i am able to see that device is connected. 

Switch model : C2960S POE. 

AP model : AIR-LAP1141N-A-K9

i have tried changing the access point in same model. but no luck. 

i am getting the same issue. 

Please help on this.

Regards,

Is DHCP Option 43 enabled or configured correctly?

[surendranaths88]

yes. 

Actually AP was working fine 2 days ago also in the same switch port. 

But after removing from that port and connected to another port in same switch , there it started this issue. 

Do you require any logs from my side?

Maybe the port configuration is incorrect?  The port may have the wrong VLANs or the allowed-VLAN has the wrong VLAN?  Maybe the VLAN database doesn't have the correct VLAN.

we have a dedicated vlan for wifi access points and it is correctly configured. 

the same vlan is allowed in the trunk port also. 

but dont know why it is not taking IP.
