Packets
The total number of packets received.
This number includes bad packets, broadcast packets, and multicast
packets.
Broadcast pkts
The total number of good packets received that were directed to the
broadcast address.
This number does not include multicast packets.
Multicast pkts
The total number of good packets received that were directed to a
multicast address.
This number does not include packets directed to the broadcast
address.
CRC alignment errors
The total number of packets received that were from 64 – 1518 octets
long, but had either a bad FCS with an integral number of octets (FCS
Error) or a bad FCS with a non-integral number of octets (Alignment
Error).
The packet length does not include framing bits but does include FCS
octets.
Undersize pkts
The total number of packets received that were less than 64 octets
long and were otherwise well formed.
This number does not include framing bits but does include FCS
octets.
Fragments
The total number of packets received that were less than 64 octets
long and had either a bad FCS with an integral number of octets (FCS
Error) or a bad FCS with a non-integral number of octets (Alignment
Error).
It is normal for this counter to increment, since it counts both runts
(which are normal occurrences due to collisions) and noise hits.
This number does not include framing bits but does include FCS
octets.
Oversize packets
The total number of packets received that were longer than 1518
octets and were otherwise well formed.
This number does not include framing bits but does include FCS
octets.
Jabbers
The total number of packets received that were longer than 1518
octets and had either a bad FCS with an integral number of octets
(FCS Error) or a bad FCS with a non-integral number of octets
(Alignment Error).
Note
: This definition of jabber is different from the definition in IEEE-
802.3 section 8.2.1.5 (10BASE5) and section 10.3.1.4 (10BASE2).
These documents define jabber as the condition where any packet
exceeds 20 ms. The allowed range to detect jabber is between 20 ms
and 150 ms.
This number does not include framing bits but does include FCS
octets.
