Chapter 16 Configuring RADIUS Features
RADIUS Packet of Disconnect
• To prevent unauthorized servers from disconnecting users, the authorizing agent that issues the POD
packet must include three parameters in its packet of disconnect request. For a session to be
disconnected, all parameters must match their expected values at the router. If the parameters do not
match, the router discards the packet of disconnect packet and sends a NACK (negative
acknowledgement message) to the agent.
The data parameters are the following RADIUS attributes:
• User- Name (RADIUS IETF attribute 1)
• Framed-IP-Address (RADIUS IETF attribute 8)
• Acct-Session-Id (RADIUS IETF attribute 44)
• Session-Svr-Key (vendor-proprietary RADIUS attribute 151)
For information about RADIUS attributes, see Appendix A, “RADIUS Attributes” .
