Version Description
9.3(0.0) Introduced on the S4810, S6000 platforms.
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.
priority-group bandwidth pfc
Configure the ETS bandwidth allocation and PFC mode used to manage port traffic in an 802.1p priority
group.
