Method for redirecting outbound VLAN traffic away from an inactive external port of a switch. A first switch monitors the active or inactive status of a designated external port. A host computer periodically queries the first switch requesting the status of the designated external port. The first switch replies to the query indicating the current status of the designated external port. If the external port is inactive, the host computer redirects data traffic away from the inactive designated external port to an alternate external port without deactivating the designated internal port. Preferably, the designated internal port continues to be used for secure internal LAN communications, such as between a host computer and a management entity. When the designated external port is again active, data traffic is returned to the designated external port.
