Configuring Protected Ports

Default Protected Port Configuration

The default is to have no protected ports defined.

Protected Port Configuration Guidelines

You can configure protected ports on a physical interface (for example, Gigabit Ethernet port 1) or an
EtherChannel group (for example, port-channel 5). When you enable protected ports for a port channel,
it is enabled for all ports in the port-channel group.
Do not configure a private-VLAN port as a protected port. Do not configure a protected port as a
private-VLAN port. A private-VLAN isolated port does not forward traffic to other isolated ports or
community ports. For more information about private VLANs, see
VLANs."

Configuring a Protected Port

Beginning in privileged EXEC mode, follow these steps to define a port as a protected port:
Command
Step 1
configure terminal
Step 2 interface interface-id
Step 3 switchport protected
Step 4 end
Step 5
show interfaces interface-id switchport
Step 6 copy running-config startup-config
To disable protected port, use the no switchport protected interface configuration command.
This example shows how to configure a port as a protected port:
Switch# configure terminal
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# switchport protected
Switch(config-if)# end
