# Configuring RADIUS-Initiated Disconnect

To configure RADIUS-initiated disconnect feature, perform the following steps to set up the RADIUS dynamic-request server that will perform the disconnect operation:

1. Configure the RADIUS dynamic-request server, and enter RADIUS Configuration mode.
   host1(config)#radius dynamic-request server 10.10.5.10 host1(config-radius)#
2. Enable the RADIUS-initiated disconnect capability on the RADIUS dynamic-request server.
   host1(config-radius)#subscriber disconnect
3. Define the secret used in the RADIUS Authenticator field during exchanges between the RADIUS dynamic-request server and the RADIUS server.
   host1(config-radius)#key Secret3Clientkey
4. (Optional) Specify the UDP port on which the RADIUS dynamic-request server listens for messages from the RADIUS server. The default is 1700.
   host1(config-radius)#udp-port 1770
