authentication command Use the authentication command {bounce-port|disable-port} ignore to disable processing of RADIUS CoA requests to bounce the host port. The no form of this command honors RADIUS CoA bounce host port requests. Syntax authentication command { bounce-port | disable-port } ignore no authentication command { bounce-port | disable-port } ignore • bounce-port-Ignore CoA requests to disable the port for 10 seconds and then re-enable it. • disable-port-Ignore CoA requests to administratively disable the port. Default Configuration By default, RADIUS CoA bounce host port requests are honored. By default, RADIUS CoA disable host port requests are honored. Command Mode Global Configuration mode User Guidelines A RADIUS CoA bounce host port command disables the port for 10 seconds by bringing the link down and then re-enables the port. The authentication command bounce-port ignore disables processing of bounce host port CoA requests and effectively prevents a link flap on the requested RADIUS authenticated port. A link flap may cause the connected devices to restart the DHCP address assignment and configuration process. If a valid and authenticated bounce port request is received from a configured CoA client and the session cannot be found, the switch returns a CoA-NAK message with the 503 Session Context Not Found response code. If a valid and authenticated request is received from a configured CoA client and the bounce port capability is administratively disabled, a CoA-NAK response is returned with 501 Administratively Prohibited response code.
