Parameter Definition
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.
NOTE
48GC modules do not support count information on oversized packets and report 0.
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.
NOTE
48GC modules do not support count information on jabbers and report 0.
Collisions The best estimate of the total number of collisions on this Ethernet segment.
64 octets pkts The total number of packets received that were 64 octets long.
This number includes bad packets.
This number does not include framing bits but does include FCS octets.
65 to 127 octets
pkts
The total number of packets received that were 65 - 127 octets long.
This number includes bad packets.
This number does not include framing bits but does include FCS octets.
128 to 255 octets
pkts
The total number of packets received that were 128 - 255 octets long.
This number includes bad packets.
This number does not include framing bits but does include FCS octets.
256 to 511 octets
pkts
The total number of packets received that were 256 - 511 octets long.
This number includes bad packets.
This number does not include framing bits but does include FCS octets.
