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.
