Step Command Remarks
2. Enter Layer 2 aggregate
interface view.

3. Configure the
description of the
aggregate interface.

By default, the description of an
interface is in the format of
interface-name Interface.
Specifying ignored VLANs on a Layer 2 aggregate interface
By default, the member ports cannot become Selected ports when the permit state and tagging mode of
each VLAN are not same for the member ports and the Layer 2 aggregate interface.
You can set a VLAN as an ignored VLAN if you want to allow member ports to be set in Selected state
even if the permit state and tagging mode of the VLAN are different between the member ports and the
Layer 2 aggregate interface.
To configure ignored VLANs on a Layer 2 aggregate interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Layer 2 aggregate
interface view.
interface bridge-aggregation
interface-number
N/A
3. Configure ignored VLANs.
link-aggregation ignore vlan
vlan-id-list
By default, a Layer 2 aggregate
interface does not ignore any
VLANs.
Setting the minimum and maximum numbers of Selected ports
for an aggregation group
IMPORTANT:
The minimum and maximum number of Selected ports must be the same for the local and peer
aggregation groups.
The bandwidth of an aggregate link increases as the number of selected member ports increases. To
avoid congestion caused by insufficient Selected ports on an aggregate link, you can set the minimum
number of Selected ports required for bringing up the specific aggregate interface.
This minimum threshold setting affects the aggregation state of both aggregation member ports and the
aggregate interface:
• When the number of member ports eligible to be selected is smaller than the minimum threshold,
all member ports change to the Unselected state and the link of the aggregate interface goes down.
• When the minimum threshold is reached, the eligible member ports change to the Selected state,
and the link of the aggregate interface goes up.
