Setting the Minimum and Maximum Number of Selected Ports
for an Aggregation Group
NOTE:
This feature is supported on the SecPath F5000-A5 only.
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.
By default, the maximum number of Selected ports allowed in an aggregation group depends on the
hardware capabilities of the member ports. After you manually configure the maximum number of
Selected ports in an aggregation group, the maximum number of Selected ports allowed in the
aggregation group is the lower value of the two upper limits. You can configure redundancy between
two ports as follows: Assign two ports to an aggregation group, and configure the maximum number of
Selected ports allowed in the aggregation group as 1. In this way, only one Selected port is allowed in
the aggregation group at any point in time, while the Unselected port serves as a backup port.
Follow these steps to set the minimum and maximum number of Selected ports for an aggregation group:
