Queue Group Behavior on LAG

Queue Group Queue Instantiation Per Link

When a port queue group is created on a Link Aggregation Group (LAG) context, it is
individually instantiated on each link in the LAG.
Per Link Queue Group Queue Parameters
The queue parameters for a queue within the queue group are used for each port queue and
are not divided or split between the port queues representing the queue group queue. For
instance, when a queue rate of 100Mbps is defined on a queue group queue, each instance of
the queue group (on each LAG port) will have a rate of 100Mbps.
Adding a Queue Group to an Existing LAG
A queue group must be created on the primary (lowest port ID) port of the LAG. If an attempt
is made to create a queue group on a port other than the primary, the attempt will fail. When
the group is define on the primary port, the system will attempt to create the queue group on
each port of the LAG. If sufficient resources are not available on each port, the attempt to
create the queue group will fail.
Any queue group queue overrides defined on the primary port will be automatically
replicated on all other ports within the LAG.
Removing a Queue Group from a LAG
A queue group must be removed from the primary port of the LAG. The queue group will be
deleted by the system from each of the port members of the LAG.
