override (RADIUS Options)

Override the Calling-Station-ID format for the string that the LAC sends to the LNS in the Calling Number AVP 22. AVP 22 is included in the incoming-call request (ICRQ) packet when the L2TP session is being established.

If you have configured the calling-station-id-format statement, the LAC sends AVP 22 in a different format that can include other information in addition to the ACI or ARI. In this case, the LNS sends the value of AVP 22 to the RADIUS server as the Calling-Station-ID attribute (31).

If you do not want the AVP 22 value to be used as the Calling-Station-ID attribute (31) for some subscribers, you can override that format in the access profile by including the calling-station-id remote-circuit-id override option. You must also configure the new format to be used with the remote-circuit-id-format statement; you can specify: the ACI, ARI, or both the ACI and ARI received from the PADR packet.

Check the SDB to determine whether the session’s LAC endpoint IP address is available. If so, use that value in the RADIUS NAS-IP-Address attribute (4). The LNS subsequently sends the attribute to the RADIUS server in Access-Request and accounting messages. If the value is not present, the attribute is not sent.

Check the SDB to determine whether the LAC NAS port information is conveyed to the LNS in the Cisco Systems NAS Port Info AVP (100). If so, use that value in the RADIUS NAS-Port attribute (5). The LNS subsequently sends the attribute to the RADIUS server in Access-Request and accounting messages. If the value is not present, the LNS sends its local IP address.

Check the SDB to determine whether the LAC NAS port information is conveyed to the LNS in the Cisco Systems NAS Port Info AVP (100). If so, override the value of the RADIUS NAS-Port-Type attribute (61) at the LNS with that value. Otherwise, use the original NAS-Port-Type in attribute 61.
