Enable link state trapping
for the aggregate
interface.
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
1.
Enter system view.
2.
Enter aggregate interface view.
3.
Set the minimum number of Selected
ports for the aggregation group.
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.
