D-Link DES-2108/E/B [120/199] Port packet analysis statistics

24-port NWay Ethernet Switch User’s Guide

106 Using the Console Interface

♦ Fragments The number of packets less than 64 bytes with

either bad framing or an invalid CRC. These are normally

the result of collisions.

♦ Jabber The number of frames with length more than 1518

bytes and with CRC error or misalignment (bad framing).

♦ Late Collision The number of collisions that occur at or

after the 64

byte (octet) in the frame.

♦ Mac Rx Error The number of frames with received MAC

Errors.

♦ Dropped Frames The number of frames which are dropped

by this port since the last Switch reboot.

♦ Undersize Frames The number of frames detected that are

less than the minimum permitted frame size of 64 bytes and

have a good CRC. Undersize frames usually indicate collision

fragments, a normal network occurrence.

♦ Total errors The sum of the CRC Error, Oversize Frames,

Fragments, Jabber, Late Collision, Mac Rx Error, Dropped

Frames, and Undersize Frames counters.

♦ Collisions The number of collision that has occurred.
