Dell S6000 FTOS 9.0(2.0) Command Line Reference Guide for the System - Page 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. show dcb S6000 Displays the data center bridging status, the number of PFC-enabled ports, and the number of PFC-enabled queues.
