Protecting Ports

When you apply port protection to ports on a switch, you prevent bridged traffic (unicast, multicast, or broadcast) from being transmitted between them. You must protect both the sending and receiving ports for the protection to be in effect. The ports can then communicate only through routing.

Note: A routed port cannot be protected.

To protect ports, choose Port > Protected Port and use the Protected Port window.
