Description: The number of times that F_BSY was returned to this port as a result of a Class 2 frame that could not be delivered to the other end of the link. This can occur when either the fabric or the destination port is temporarily busy. Note that this counter will never increment for an F_Port.

What is fcmPortClass2RxFbsyFrames?

This Counter64 counts how many times this port received an F_BSY response after a Class 2 frame it sent could not be delivered because the fabric or destination port was temporarily busy; it never increments on an F_Port itself. Frequent F_BSY responses tell an admin the far end of the fabric or destination device is congested rather than the local port.
