The icmp port-unreachable send command enables an interface to send ICMP Port Unreachable messages. The undo icmp port-unreachable send command disables an interface from sending ICMP Port Unreachable messages. By default, an interface is enabled to send ICMP Port Unreachable messages. Format icmp po...
