5508 Enable Option 82

Ed Willson — Mon, 05 Jul 2021 08:57:16 GMT

I've enabled option 82 on the WLC, but when I watch clients pull DHCP the 82 option isn't showing up in wireshark.

Any Thoughts?

Thanks,

This should help you to understand DHCP option 82 behavior (these are based on 7.0.116.0 code & refer config guides for exact command syntax if other version used)

(Cisco Controller) >show dhcp opt-82

DHCP Opt-82 RID Format: <AP Ethernet MAC Address>
DHCP Opt-82 Format: ascii

But when a client requesta an address there is no 82 option there:
