Users Guide

The number of ports supported based on lossless queues configured will depend on the buffer. The default number of PFC queues in
the system is two.
For each priority, you can specify the shared buffer threshold limit, the ingress buffer size, buffer limit for pausing the acceptance of
packets, and the buffer offset limit for resuming the acceptance of received packets.
4 Configure the profile name for the DCB buffer threshold
CONFIGURATION mode
dcb-buffer-threshold dcb-buffer-threshold
5
DCB-BUFFER-THRESHOLD mode
priority 0 buffer-size 52 pause-threshold 16 resume-offset 10 shared-threshold-weight 7
6 Assign the DCB policy to the DCB buffer threshold profile on the backplane.
CONFIGURATION mode
dcb-policy buffer-threshold linecard {linecard-number | all} port-set {port-pipe | all}
backplane all dcb-policy-name
7 Assign the DCB policy to the DCB buffer threshold profile on interfaces. This setting takes precedence over the default buffer-
threshold setting.
INTERFACE mode (conf-if-te)
dcb-policy buffer-threshold buffer-threshold
8 Configuring Global total buffer size on linecards.
CONFIGURATION mode
dcb pfc-total-buffer-size buffer-size linecard {linecard-number | all}
Line card number range is from 0 to 2.
9 Configuring global shared buffer size on linecards.
CONFIGURATION mode
dcb pfc-shared-buffer-size buffer-size linecard {linecard-number | all} [port-set {port-pipe
| all}]
