Administrator Guide

Using the priority-pgid command, you assign each 802.1p priority to one priority group. A priority
group consists of 802.1p priority values that are grouped together for similar bandwidth allocation and
scheduling, and that share latency and loss requirements. All 802.1p priorities mapped to the same queue
must be in the same priority group. For example, the priority-pgid 0 0 0 1 2 4 4 4 command
creates the following groups of 802.1p priority traffic:
● Priority group 0 contains traffic with dot1p priorities 0, 1, and 2.
● Priority group 1 contains traffic with dot1p priority 3.
● Priority group 2 contains traffic with dot1p priority 4.
● Priority group 4 contains traffic with dot1p priority 5, 6, and 7.
To remove a priority-pgid configuration from a DCB map, enter the no priority-pgid command.

Commands
priority-group bandwidth pfc— Configures the ETS bandwidth allocation and the PFC setting used to
manage the port traffic in an 802.1p priority group.
qos-policy-output ets
To configure the ETS bandwidth allocation and scheduling for priority traffic, create a QoS output policy.
Syntax
qos-policy-output policy-name ets
To remove the QoS output policy, use the no qos-policy-output ets command.
Parameters
policy-name Enter the policy name. The maximum is 32 characters.

Version Description
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
If an error occurs in an ETS output-policy configuration, the configuration is ignored and the scheduler
and bandwidth allocation settings are reset to the ETS default values (all priorities are in the same ETS
priority group and bandwidth is allocated equally to each priority).
If an error occurs when a port receives a peer’s ETS configuration, the port’s configuration is reset to the
previously configured ETS output policy. If no ETS output policy was previously applied, the port is reset
to the default ETS parameters.
