Aggregator and MXL 10/40GbE Switch.
Usage
Information
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 TLV are supported. DCBx also validates PFC configurations
received in TLVs from peer devices.
By applying a DCB input policy with PFC enabled, you enable PFC operation on
ingress port traffic. To achieve complete lossless handling of traffic, also enable
PFC on all DCB egress ports or configure the dot1p priority-queue assignment of
PFC priorities to lossless queues (refer to pfc no-drop queues).
To remove a DCB input policy, including the PFC configuration it contains, enter
the no dcb-input policy-name command in Interface Configuration mode.

Usage
Information
If you apply an input policy with PFC disabled (no pfc mode on):
• You can enable link-level flow control on the interface. To delete the input
policy, first disable link-level flow control. PFC is then automatically enabled on
the interface because an interface is by default PFC-enabled.
