Supported Attributes in Disconnect Request Messages
The following tables list the RADIUS attributes and 3GPP VSAs supported by the MobileNext Broadband Gateway in RADIUS Disconnect Request messages. A Disconnect Request message is sent by the RADIUS server to terminate a user session on a NAS and discard all associated session contexts.
The broadband gateway listens on UDP ports 1700 and 3799 for RADIUS Disconnect Request messages sent from the RADIUS server. The user session identified by the Disconnect Request message is deleted on the broadband gateway.
