Data Center Bridging (DCB) | 329
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
re-apply the policy to an interface.
The maximum number of lossless queues supported on the switch is two.
The configured priority traffic must be supported by a PFC peer (as detected by DCBX) for PFC to be
applied.
