Usage
Information
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.
The maximum number of lossless queues supported on the switch is two.
A PFC peer must support the configured priority traffic (as detected by DCBX) to apply PFC.
