Users Guide

The number of ports supported based on lossless queues congured will depend on the buer. The default number of PFC queues in
the system is two.
For each priority, you can specify the shared buer threshold limit, the ingress buer size, buer limit for pausing the acceptance of
packets, and the buer oset limit for resuming the acceptance of received packets.
4 Congure the prole name for the DCB buer 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 buer threshold prole 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 buer threshold prole on interfaces. This setting takes precedence over the default buer-
threshold setting.
INTERFACE mode (conf-if-te)
dcb-policy buffer-threshold buffer-threshold
8 Conguring Global total buer 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 Conguring global shared buer size on linecards.
CONFIGURATION mode
dcb pfc-shared-buffer-size buffer-size linecard {linecard-number | all} [port-set {port-pipe
| all}]
