Defining CoS Queue Scheduling Priority
You can configure the scheduling priority of individual queues by specifying the priority in a scheduler, and then associating the scheduler with a queue by using a scheduler map. Queues can have one of two bandwidth priorities:
- strict-high —The
scheduler has strict-high priority. You can configure only one queue
as a strict-high priority queue. Strict-high priority allocates the
scheduled bandwidth to the queue before any other queue receives bandwidth.
Other queues receive the bandwidth that remains after the strict-high
queue has been serviced.
We recommend that you always apply a shaping rate to strict-high priority queues to prevent them from starving other queues. If you do not apply a shaping rate to limit the amount of bandwidth a strict-high priority queue can use, then the strict-high priority queue can use all of the available port bandwidth and starve other queues on the port.
- low—Low priority. Traffic with this priority is serviced after any queue that has a strict-high priority.
- To configure queue priority using the CLI:
[edit class-of-service]
user@switch# set schedulers scheduler-name priority level
