How static link aggregation groups are built

Reference port selection process

When setting the aggregation states of the ports in an aggregation group, the system automatically chooses a member port as the reference port. A Selected port must have the same operational key and attribute configurations as the reference port.

The system chooses a reference port from the member ports in the up state. The first member interface which is operationally up is selected as reference port.

Setting the aggregation state of each member port

After the reference port is chosen, the system sets the aggregation state of each member port in the static aggregation group.

Setting the aggregation state of a member port in a static aggregation group

After the maximum limit of members is reached in a LAG, additional port cannot be added in to the aggregation group. Any operational keys/attributes or configuration changes might affect the aggregation states of the member ports.
