Usage
Information
PFC and ETS settings are not pre-configured on Ethernet ports. You must use the
dcb-map command to configure different groups of 802.1p priorities with PFC and
ETS settings.
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.
