Chapter 25 Configuring Port-Based Traffic Control
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
Chapter 16, “Configuring Private
VLANs.”
Configuring a Protected Port
Beginning in privileged EXEC mode, follow these steps to define a port as a protected port:
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
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
interface
interface-id
Specify the interface to be configured, and enter interface
configuration mode.
Step 3
switchport protected
Configure the interface to be a protected port.
Step 4
end
Return to privileged EXEC mode.
Step 5
show interfaces
interface-id
switchport
Verify your entries.
Step 6
copy running-config startup-config
(Optional) Save your entries in the configuration file.
