• 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

dcb-map — creates a DCB map to configure PFC and ETS parameters and applies

the PFC and ETS settings on Ethernet ports.

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.

pfc mode on

Enable the PFC configuration on the port so that the priorities are included in DCBX negotiation with peer

PFC devices.

History

Version 9.3.0.0 Introduced on the M I/O Aggregator and MXL 10/40GbE

Switch with the FC Flex IO module.

Usage

Information

By applying a DCB input policy with PFC enabled, you enable PFC operation on

ingress port traffic. To achieve complete lossless handling of traffic, also enable

PFC on all DCB egress ports or configure the dot1p priority-queue assignment of

PFC priorities to lossless queues (refer to pfc no-drop queues).

To disable PFC operation on an interface, enter the no pfc mode on command in

DCB Input Policy Configuration mode. PFC is enabled and disabled as global DCB

operation is enabled (dcb-enable) or disabled (no dcb-enable).

You cannot enable PFC and link-level flow control at the same time on an

interface.

Commands

dcb-input — creates a DCB input policy.
