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).
