Queue Group Behavior On Lag - Alcatel-Lucent 7950 Quality Of Service Manual

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.
