When the number of member ports eligible to be Selected is smaller than the minimum threshold:
{
All member ports change to the Unselected state.
{
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.
The maximum number of Selected ports allowed in an aggregation group is limited by either the
configured maximum number or hardware capability, whichever value is smaller.
You can configure backup between two ports by performing the following tasks:
•
Assign two ports to an aggregation group.
•
Configure the maximum number of Selected ports allowed in the aggregation group as 1.
Then, only one Selected port is allowed in the aggregation group at any point in time, while the
Unselected port serves as a backup port.
To set the minimum and maximum numbers of Selected ports for an aggregation group:
