User-Name: The value should exactly match the subscriber name of the session. This is one of the preferred
methods of subscriber session identification.
Framed-IP-Address: The values should exactly match the framed ip address of the session.
Calling-station-id: The value should match the Mobile Station ID.
To specify the ACL to apply to the subscriber session, use the following attribute:
Filter-ID: CoA only. This must be the name of an existing Access Control List. If this is present in a CoA
request, the specified ACL is immediately applied to the specified subscriber session. The Context
Configuration mode command, radius attribute filter-id direction, controls in which direction filters are
