 To implement the option 82 function of DHCP Relay Agent, the “debug dhcp relay packet” command

can be used during the operating procedure, including adding the contents of option 82, the

retransmitting policy adopted, the option 82 contents of the server peeled by the Relay Agent and etc.,

such information can help users to do troubleshooting.

 To implement the option 82 function of DHCP server, the “debug ip dhcp server packet” command can

be used during the operating procedure to display the procedure of data packets processing of the

server, including displaying the identified option 82 information of the request message and the option

82 information returned by the reply message.
