# RADIUS Dynamic-Request Server Commands

This section describes commands used to configure RADIUS dynamic-request servers.

authorization change

- Use to enable the RADIUS dynamic-request server to receive CoA messages, such as packet mirroring attributes and Service Manager attributes, from the RADIUS server.
- Example
  host1(config)#radius dynamic-request server 192.168.5.3 host1(config-radius)#authorization change
- Use the no version to disable receipt of the messages; any currently configured operations will continue.
- See authorization change

key

- Use to define the key (secret) that is used to calculate the RADIUS Authenticator field during exchanges between the RADIUS dynamic-request server and the RADIUS server.
- If no key is specified, the router drops all requests from the RADIUS server.
- Example
  host1(config-radius)#key Secret3Clientkey
- Use the no version to set the default, no Authenticator.
- See key

radius disconnect client

- Use to configure a RADIUS disconnect client and enter RADIUS Configuration mode. Include the IP address of the RADIUS server that is acting as the disconnect client.
- Example
  host1(config)#radius disconnect client 10.10.5.10 host1(config-radius)#
- Use the no version to remove the RADIUS disconnect client.

  | Note: The function of this command has been replaced by a combination of the RADIUS dynamic-request server feature and the subscriber disconnect command. This command might be removed completely in a future release.

- See radius disconnect client

radius dynamic-request server

- Use to configure a RADIUS dynamic-request server and enter RADIUS Configuration mode. Specify the IP address of the RADIUS server that exchanges messages with the RADIUS dynamic-request server.
- Example
  host1(config)#radius dynamic-request server 10.10.5.10 host1(config-radius)#
- Use the no version to unconfigure the RADIUS dynamic-request server.
- See radius dynamic-request server

subscriber disconnect

- Use to enable the RADIUS dynamic-request server to receive RADIUS disconnect messages from a RADIUS server.
- Example
  host1(config-radius)#subscriber disconnect
- Use the no version to disable processing of disconnect packets.

  | Note: This command and the RADIUS dynamic-request server feature replace the radius disconnect client command, which may be removed completely in a future release. The RADIUS Disconnect Configuration mode is also deprecated.

- See subscriber disconnect

udp-port

- Use to specify the UDP port on which the RADIUS dynamic-request server listens to receive messages from the RADIUS server.
- Example
  host1(config-radius)#udp-port 1770
- Use the no version to return to the default, port 1700.
- See udp-port
