Description: This object is a count of null addressed packets that have been received on this port. This counter is incremented by one for each frame received on this port with a destination MAC address consisting of all zero bits. Both void and training frames are included in this counter.

This counter may experience a discontinuity when the value of the corresponding instance of vgRptrPortLastChange changes.

What is vgRptrPortNullAddressedFrames?

Counts frames received on this port whose destination MAC address is all zero bits, including both void and training frames. An admin sees a rising count here mainly during normal link training activity on a port rather than as an error condition.
