Description: This attribute records the number of times that the bus tap was unable to receive a frame from the bus because all of its bus receive channels were in use. Each occurrence results in the loss of the frame. This type of event may occur during normal operation of the module, for example when the module is operating in single bus mode; it may also be caused by a hardware fault. The attribute's value wraps around to zero when it exceeds the maximum permitted value.

What is mscShelfCardBusTapFrmCongestionErrors?

A wrapping counter of frames the bus tap failed to receive because all of its bus receive channels were already busy; this can occur normally in single-bus mode but persistent growth suggests the tap is overloaded or has a fault.
