N/A
3. Enable loopback testing. loopback { external | internal }
Optional.
Disabled by default.
Support for the external and
internal keywords may vary
depending on your device model.

NOTE:
•
On an interface that is physically down, you can only perform internal loopback testing. On an interface
administratively shut down, you cannot perform internal or external loopback testing.
• The speed, duplex, and shutdown commands are unavailable during loopback testing.
• During loopback testing, an Ethernet interface operates in full duplex mode. When you disable
loopback testing, the duplex configuration of the interface restores.

Configuring a port group
Some interfaces on your device may use the same set of settings. To configure these interfaces in bulk
rather than one by one, you can assign them to a port group.
You create port groups manually. All settings made for a port group apply to all the member ports of the
group. For example, you can configure a traffic suppression threshold (see " Configuring storm
suppression ") for multiple interfaces in bulk by assigning these interfaces to a port group.
Even though the settings are made on the port group, they are saved on an interface basis rather than on
a port group basis. You can only view the settings in the view of each interface by use the display
current-configuration or display this command.
To configure a manual port group:
