Usage Information
PFC and ETS settings are not pre-congured on Ethernet ports. You must use the dcb-map command to
congure dierent 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 trac:
• Priority group 0 contains trac with dot1p priorities 0, 1, and 2.
• Priority group 1 contains trac with dot1p priority 3.
• Priority group 2 contains trac with dot1p priority 4.
• Priority group 4 contains trac with dot1p priority 5, 6, and 7.
To remove a priority-pgid conguration from a DCB map, enter the no priority-pgid command.
For PFC enabled priorities, it is recommended to map single priority per Priority group.
pfc mode on
Enable the PFC conguration on the port so that the priorities are included in DCBX negotiation with peer PFC devices.
Syntax
pfc mode on
To disable the PFC conguration, use the no pfc mode on command.
Defaults PFC mode is on.
