Configuring a Layer 2 Ethernet interface
Configuring a port group
Some interfaces on your device might 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
suppr
ession for Ethernet interfaces") 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 each interface basis rather than
on a port group basis. You can only view the settings in the view of each interface by using the display
current-configuration or display this command.
To configure a manual port group:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Create a manual port
group and enter manual
port group view.
port-group manual
port-group-name
N/A
3. Assign Ethernet interfaces
to the manual port group.
group-member interface-list
If you use the group-member
interface-type interface-start-number to
interface-type interface-end-number
command to add multiple ports in batch
to the specified port group, make sure
that all these ports are of the same type
and on the same interface card, and the
interface-end-number argument must be
greater than the interface-start-number
argument.
Configuring storm suppression for Ethernet interfaces
You can use the storm suppression function to limit the size of a particular type of traffic (broadcast,
multicast, or unknown unicast traffic) that can be received on a per-interface basis in Ethernet interface
view or port group view. In interface or port group view, you set the maximum size of broadcast, multicast
or unknown unicast traffic allowed to be received on an interface or each interface in a port group.
When the broadcast, multicast, or unknown unicast traffic received on the interface exceeds this
threshold, the system discards packets until the traffic drops below this threshold.
