Subscriber Services: Option 82 suboptions in authentication usernames for autosense VLANs

You can specify the option 82 suboptions that are concatenated with the username during the authentication process for autosense VLANs. 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. You can specify either both or neither of the Agent Circuit ID (suboption 1) and the Agent Remote ID (suboption 2). 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 use of option 82 suboptions is supported for DHCPv4 discover packets only.
