switchport protected
Use the switchport protected command in Interface Configuration mode to configure a protected
port. The
groupid parameter identifies the set of protected ports to which this interface is assigned.
You can only configure an interface as protected in one group. You are required to remove an
interface from one group before adding it to another group.
Port protection occurs within a single switch. Protected port configuration does not affect traffic
between ports on two different switches. No traffic forwarding is possible between two protected
ports.
