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, you must 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
Create a DCB output policy to associate a priority group with an ETS output policy with scheduling
and bandwidth configuration. You can apply a DCB output policy on multiple egress ports. When you
apply an ETS output policy on an interface, ETS-configured scheduling and bandwidth allocation take
precedence over any configured settings in QoS output policies.
