    摘要: A network switch comprises a port that includes a redirect circuit and a loopback circuit that selectively redirects an egress frame to the redirect circuit when the port is non-operational. The redirect circuit replaces a destination port identifier associated with the egress frame to create a modified frame. The loopback circuit loops back the modified frame in an ingress direction. A transfer circuit transfers the modified frame to another port identified by the destination port identifier.
