Introduced on MXL 10/40GbE Switch IO Module Related Commands dcb-input Create a DCB input policy. 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.
