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
).
