Usage Information
By default, iSCSI is disabled and flow control is not configured on any interfaces or if link-level flow
control is enabled on one or more interfaces. To enable DCB, do one of the following:
• Apply the dcb-input policy command with the command no pfc-mode on to all the interfaces.
• Disable flow-control on all of the interfaces.
Example
FTOS(conf)#dcb enable
pfc-queues PFC lossless queues profile
dcb-input
Create a DCB input policy to apply pause or flow control for specified priorities using a configure
delay time.
Syntax
dcb-input policy-name
To delete the DCB input policy, use the no dcb-input command.

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, you must also enable PFC on all DCB egress ports or
configure the dot1p priority-queue assignment of PFC priorities to lossless queues (see 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.
