Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the M I/O Aggregator.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
By default:
● All 802.1p priorities are grouped in priority group 0.
● 100% of the port bandwidth is assigned to priority group 0. The complete bandwidth is equally
assigned to each priority class so that each class has 12 to 13%.
NOTE: Please note that Dell Networking does not recommended to use this command as it has
been deprecated in the current 9.4(0.0) release. A warning message appears when you try to run
this command indicating that you have to use the dcb-map commands in the future.
scheduler
Configure the method used to schedule priority traffic in port queues.
Syntax
scheduler value
To remove the configured priority schedule, use the no scheduler command.
Parameters
value Enter schedule priority value. The valid values are:
● strict: strict-priority traffic is serviced before any other queued traffic.
● werr: weighted elastic round robin (werr) provides low-latency scheduling for
priority traffic on port queues.
Defaults Weighted elastic round robin (WERR) scheduling is used to queue priority traffic.

9.4(0.0) Supported on the FN I/O Aggregator.
9.2(0.0) Introduced on the M I/O Aggregator.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
dot1p priority traffic on the switch is scheduled to the current queue mapping. dot1p priorities within the
same queue must have the same traffic properties and scheduling method.
ETS-assigned scheduling applies only to data queues, not to control queues.
The configuration of bandwidth allocation and strict-queue scheduling is not supported at the same
time for a priority group. If you configure both, the configured bandwidth allocation is ignored for priority-
group traffic when you apply the output policy on an interface.
