• Fragments — Displays the number of fragments (packets with less than 64 octets,
excluding framing bits, but including FCS octets) received on the interface since
the device was last refreshed.
• Jabbers — Displays the
total number of received packets that were longer than
1518 octets. This number excludes frame bits, but includes FCS octets that had either
a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error)
or a bad FCS with a non-integral octet (Alignment Error) number. The field range to
detect jabbers is between 20 ms and 150 ms.
• Collisions — Displays the number of collisions received on the interface since the
device was last refreshed.
• Frames of xx Bytes — Number of xx-byte frames received on the interface since
the device was last refreshed.
