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. A RADIUS CoA disable host port command administratively disables the port. A RADIUS CoA disabled port requires administrative intervention to reenable the port using the no shutdown command. The authentication command disable-port ignore disables processing of the CoA disable port request. If a valid and authenticated disable host 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 disable host port capability is administratively disabled, a CoA-NAK response is returned with 501 Administratively Prohibited response code.
