Administrator Guide
The number of ports supported based on lossless queues congured will depend on the buer. The default number of PFC queues in
the system is two.
For each priority, you can specify the shared buer threshold limit, the ingress buer size, buer limit for pausing the acceptance of
packets, and the buer oset limit for resuming the acceptance of received packets.
4 Congure the prole name for the DCB buer 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 buer threshold prole 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 buer threshold prole on interfaces. This setting takes precedence over the default buer-
threshold setting.
INTERFACE mode (conf-if-te)
dcb-policy buffer-threshold buffer-threshold
8 Conguring Global total buer 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 Conguring global shared buer size on linecards.
CONFIGURATION mode
dcb pfc-shared-buffer-size buffer-size linecard {linecard-number | all} [port-set {port-pipe
| all}]
