Explanation
Configuring trust of CoS on the interface is a requirement for implementing Priority Flow Control (PFC) on an ArubaOS-CX switch interface. PFC is a feature that allows a switch to pause traffic on a per-class basis using IEEE 802.1Qbb frames. To use PFC, the switch must trust the CoS values in the incoming frames and map them to priority groups and queues.
