Hierarchy Level


Specify that the option 82 information from the client PDU is concatenated with the username during the subscriber authentication process.

For autosense VLANs, you can additionally specify Option 82 suboption information that is concatenated with the username. You can specify either both or neither of the Agent Circuit ID (suboption 1) and Agent Remote ID (suboption 1). If you specify both, the Agent Circuit ID is supplied first, followed by a delimiter, and then the Agent Remote ID. If you specify that neither suboption is supplied, the raw payload of Option 82 from the PDU is concatenated to the username.


The option 82 value used in creating the username is based on the option 82 value that is encoded in the incoming DHCP discover packet. The use of suboptions is supported for DHCPv4 only.



Use the raw payload of Option 82 from the PDU.


(Optional) Use the Agent Circuit ID suboption (suboption 1).


(Optional) Use the Agent Remote ID suboption (suboption 2).
