Octets
This counter is incremented once for every data octet of all received
packets. This includes data octets of rejected and local packets that are not
forwarded to the switching core for transmission. This counter should reflect
all the data octets received on the line.
For oversized packets, when they exceed the allocated buffer-size, only
buffer-size bytes are counted and all the rest of the bytes are not.
Collisions
This counter is incremented once for every received packet when a
Collision Event has been detected.
Broadcast
This counter is incremented once for every good Broadcast packet received.
Multicast
This counter is incremented once for every good Multicast packet received.
CRCalignErrors
This counter is incremented once for every received packet that meets all
the following conditions:
Packet data length is between 64 and MaxFrameSize bytes inclusive.
Packet has invalid CRC (non-A also counted packets with an odd number of
nibbles).
Collision Event has not been detected.
Late Collision Event has not been detected.
Undersize
This counter is incremented once for every received packet that meets all
the following conditions:
Packet data length is less than 64 bytes.
Collision Event has not been detected.
Late Collision Event has not been detected.
Packet has valid CRC.
