Configure the shared PFC buffer size and the total buffer size. A maximum of 4 lossless queues are supported.

CONFIGURATION mode

dcb pfc-shared-buffer-size value

dcb pfc-total-buffer-size value

The buffer size range is from 0 to 3399. Default is 3088.

Configure the number of PFC queues.

CONFIGURATION mode

dcb enable pfc-queues pfc-queues

The number of ports supported based on lossless queues configured depends on the buffer. The default number of PFC queues in the

system is one.

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.

Configure the profile name for the DCB buffer 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

Assign the DCB policy to the DCB buffer threshold profile.

CONFIGURATION mode

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)

Sample DCB Configuration

The following shows examples of using PFC and ETS to manage your data center traffic.

In the following example:

Incoming SAN traffic is configured for priority-based flow control.

Outbound LAN, IPC, and SAN traffic is mapped into three ETS priority groups and configured for enhanced traffic selection (bandwidth

allocation and scheduling).

One lossless queue is used.
