Port Packet Analysis Statistics - D-Link DES-3624i User Manual

Stackable NWay Ethernet Switch User's Guide
Jabber The number of frames with length more than 1536 bytes and with CRC error or misalignment (bad
framing).
Late Collision Counts collisions that occur at or after the 64

MAC Rx Error
encodings. This may indicate noise on the line.
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 best estimate of the total number of collisions on this Ethernet segment.
