Version Description

9.8(1.0) Introduced on the Z9100–ON.
9.7(0.0) Introduced on the S6000-ON and Z9500.
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.
For PFC enabled priorities, it is recommended to map single priority per Priority group.
priority-group bandwidth pfc
Configure the ETS bandwidth allocation and PFC mode used to manage port traffic in an 802.1p priority group.
Syntax priority-group group-num {bandwidth percentage | strict-priority} [[ committed |
peak ] | [ peak | committed ] {<0-10000>} [<0-10000>]] pfc {on | off}
