Setting the minimum number of Selected ports for an
aggregation group
The bandwidth of an aggregate link increases along with the number of selected member ports. 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:
•
All member ports change to the Unselected state and the link of the aggregate interface goes down,
when the number of member ports eligible for being selected is smaller than the minimum
threshold.
•
When the minimum threshold is reached, the eligible member ports change to the Selected state,
and the link of the aggregate interface goes up.
To set the minimum number of Selected ports for an aggregation group:
Step Command
Remarks
1.
Enter system view.

N/A
2.
Enter aggregate interface view.
•
Enter Layer 2 aggregate
interface view:
interface
bridge-aggregation
interface-number
•
Enter Layer 3 aggregate
interface view:
interface
route-aggregation
interface-number
Use either command.
3.
Set the minimum number of Selected
ports for the aggregation group.
link-aggregation
selected-port minimum
number
By default, the minimum number
of Selected ports is not
specified.
CAUTION:
•
If you set this minimum threshold for a static aggregation group, you must also make the same setting for
its peer aggregation group to guarantee correct aggregation.
•
Configuring the minimum number of Selected ports required to bring up an aggregation group may
cause all the member ports in the current aggregation group to become unselected.
