2 (Optional) Configure the method used to
schedule priority traffic in port queues. Valid
values:
• strict - Strict priority traffic is serviced before
any other queued traffic (refer to Strict-priority
Queueing).
• werr - Weighted elastic round robin provides
low-latency scheduling for priority traffic on
port queues.
Default: WERR scheduling is used to queue
priority traffic.
Note: If you configure a scheduling
method, you cannot configure bandwidth
allocation in Step 3.

3 (Optional) Configure the bandwidth percentage
allocated to priority traffic in port queues.
Percentage range: 1 to 100% in units of 1%.
The sum of bandwidth percentage assigned to
dot1p priorities/queues in a priority group
should be 100%.
Default: None.
