Manual Configuration of the NAS-Port-ID RADIUS Attribute
Subscriber management uses the NAS-Port-ID (RADIUS attribute 87) to provide an interface description that identifies the physical interface that is used to authenticate subscribers. The NAS-Port-ID is included in RADIUS Access-Request, Acct-Start, Acct-Stop, Acct-On, and Acct-Off messages.
You can configure access profiles to specify additional information in the NAS-Port-ID. The additional information can be any combination of the interface description (the default value), the Agent Circuit ID, the Agent Remote ID, and the NAS identifier. You can also specify an optional delimiter character, which separates the values in a NAS-Port-ID. The default delimiter character is the hash character (#).
A default NAS-Port-ID consists of the following interface-description string:
[physical-interface].<interface-type>-<slot>/<adapter>/<port><.subinterface>[:<svlan>-<vlan>]
For example: ge-1/2/0.100:100
You might optionally configure an access profile that specifies that the NAS-Port-ID includes the NAS identifier, the Agent Circuit ID, and the Agent Remote ID, in addition to the default interface description. For this configuration, the NAS-Port-ID consists of the following string:
nas-identifier#interface-description#agent-circuit-id#agent-remote-id
For example:
retailer25#ge-1/2/0.100:100#ACI 12/1/22/1230:1.1.23#ARI 55/2/23.9999:10.11.1923
 | Note: The NAS-Port-ID displays the configured values in the following order (where # is the delimiter): nas-identifier#interface-description#agent-circuit-id#agent-remote-id |
