Release Information Statement introduced in Junos OS Release 9.1.
Statement introduced in Junos OS Release 12.3R2 for EX Series switches.
Description Specify the option 82 that is concatenated with the username during the subscriber
authentication or client authentication process. You can specify either, both, or neither
the Agent Circuit ID and the Agent Remote ID suboptions. If you specify both, the Agent
Circuit ID is supplied first, followed by a delimiter, and then the Agent Remote ID. If neither
suboption is supplied, the raw payload of option 82 is concatenated to the username.
NOTE: The option 82 value used in creating the username is based on the
option 82 value that is encoded in the outgoing (relayed) PDU.
Options circuit-id—(Optional) The string for the Agent Circuit ID suboption (suboption 1).
remote-id—(Optional) The string for the Agent Remote ID suboption (suboption 2).
Required Privilege
