Version 9.2(0.0) Supported on the M I/O Aggregator.
Usage
Information
This command is supported in Programmable-Mux (PMUX) mode only.
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, converged
enhanced ethernet (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.
