Configuring Protected Ports

NOTE: Although 2960/3560 switches do not support private VLANs, they do support protected ports, which has a similar functionality to PVLANs on a perswitch basis.

Switch(config)#interface fastethernet 0/17

Moves to interface config mode

Switch(config-if)#switchport protected

Configures interface to be a protected port

NOTE: The use of protected ports ensures that there is no exchange of unicast, broadcast, or multicast traffic between these ports on the switch. Only control traffic will be forwarded. All data traffic passing between protected ports must be forwarded through a Layer 3 device.

Switch(config-if)#exit

Returns to global config mode
