A valid frame has a good FCS and its size is greater than 64

 

bytes and less than 1518 for non tagged frames, 1522 for

 

tagged frames, or 1535 if MaxFrameSize =1 (set in global

 

control register).

 

InBroadcasts

Total valid frames received with destination address equal to

 

FF:FF:FF:FF:FF:FF.

 

InPause

Total pause frames received.

 

InMulticasts

Total valid frames received with multicast destination address that

 

are not counted in InBroadcasts or InPause.

fragments and jabbers are included, The count includes the FCS

 

but not the preamble.
