TABLE 35

Parameter

Definition

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.

512 to 1023 octets
pkts

The total number of packets received that were 512 - 1023 octets long.

This number includes bad packets.

This number does not include framing bits but does include FCS octets.

1024 to 1518
octets pkts

The total number of packets received that were 1024 - 1518 octets long.

This number includes bad packets.

This number does not include framing bits but does include FCS octets.
