CONFIGURATION mode

dcb pfc-shared-buffer-size 4000

dcb pfc-total-buffer-size 5000

NOTE: For dcb pfc-shared-buffer-size, the range is from

<0-11210>

in KB (default LC=2496/SFM=3328)

For dcb pfc-total-buffer-size, the range is from <0-11210> in KB(default LC=7488/SFM=7596)

3. Congure the number of PFC queues.

CONFIGURATION mode

dcb enable pfc-queues pfc-queues

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 S4810 and Z9500, and one for S6000 platforms.

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

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 stack ports.

CONFIGURATION mode

Dell(conf)# dcb-policy buffer-threshold stack-unit all stack-ports 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 stack ports.

CONFIGURATION mode

dcb pfc-total-buffer-size buffer-size stack-unit all port-set {port-pipe |all}

Port-set number range is from 0 to 3.
