Configuring Priority for FEX

If you do not specify the priority, the system-defined egress pq queues behave as normal queues. For information
on the system-defined type queuing class maps, see the
You can configure only one level of priority on an egress priority queue. You use the system-defined priority
queue class for the type of module to which you want to apply the policy map.
For the nonpriority queues, you can configure how much of the remaining bandwidth to assign to each queue.
By default, the device evenly distributes the remaining bandwidth among the nonpriority queues.
When a priority queue is configured, the other queues can only use the remaining bandwidth in the same

policy map.
When configuring priority for one class map queue (SPQ), you need to configure the priority for QoS
Note
group 3. When configuring priority for more than one class map queue, you need to configure the priority
on the higher numbered QoS groups. In addition, the QoS groups need to be adjacent to each other. For
example, if you want to have two SPQs, you have to configure the priority on QoS group 3 and on QoS
group 2.
Before You Begin
Before configuring the FEX, enable feature-set fex.
