You can enable any number of 802.1p priorities for PFC. Queues to which PFC
Information
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 I/O Aggregator switch
is four.
A PFC peer must support the configured priority traffic (as DCBX detects) to apply
PFC.
