Configuration manual

The range (in quanta) is from 712 to 65535.

The default is 45556 quantum in link delay.

3. Configure the CoS traffic to be stopped for the specified delay.

DCB INPUT POLICY mode

pfc priority priority-range

Enter the 802.1p values of the frames to be paused.

The range is from 0 to 7.

The default is none.

Maximum number of loss less queues supported on the switch: 2.

Separate priority values with a comma. Specify a priority range with a dash, for example: pfc priority

1,3,5-7.

4. Enable the PFC configuration on the port so that the priorities are included in DCBx negotiation with

peer PFC devices.

The default is PFC mode is on.

5. (Optional) Enter a text description of the input policy.

9. Repeat Steps 1 to 8 on all PFC-enabled peer interfaces to ensure lossless traffic service.

Dell Networking OS Behavior: As soon as you apply a DCB policy with PFC enabled on an interface,

DCBx starts exchanging information with PFC-enabled peers. The IEEE802.1Qbb, CEE, and CIN versions

of PFC Type, Length, Value (TLV) are supported. DCBx also validates PFC configurations that are received

in TLVs from peer devices.
