Show Dcb - Dell C9000 Series Reference Manual

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 DCBX detects) to apply PFC.

show dcb

Display the data center bridging status, the number of PFC-enabled ports, and the number of PFC-enabled
queues.
