Usage Information
NOTE: Please note that Dell Networking do not recommend to use this command as it has been
deprecated in the current 9.4.(0.0) release. A warning message appears when you try to run this
command indicating that you have to use the dcb-map commands in the future.
You can enable any number of 802.1p priorities for PFC. Queues to which PFC priority traffic is mapped are
lossless by default. Traffic may be interrupted due to an interface flap (going down and coming up) when you
reconfigure the lossless queues for no-drop priorities in a PFC input policy and reapply the policy to an interface.
