Q:

How to check the wireless network name or SSID information  when using option 82 in IAP?



A:

 

Option 82 was designed to allow a DHCP Relay Agent to insert circuit specific information into a request that is being forwarded to a DHCP server. Specifically the option works by setting the sub-options Circuit ID in DHCP packets.

In a wireless network, this would likely be a SSID name. Here "STSTEM BOLAGET" is used as SSID name which is highlighted in the pcap.

 

 DHCP Configuration :

 

 ip dhcp test
