History
Version 9.2(0.0) Introduced on the M I/O Aggregator. This command is
supported in Programmable-Mux (PMUX) mode only.
Version 8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
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 I/O Aggregator switch
is four.
A PFC peer must support the configured priority traffic (as DCBX detects) to apply
PFC.
priority-pgid
Assign 802.1p priority traffic to a priority group in a DCB map.
