• CRC Align Errors — Displays the number of CRC and Align errors that have occurred on the
interface since the device was last refreshed.
• Undersize Packets — Displays the number of undersized packets (less than 64 octets) received on
the interface since the device was last refreshed.
• Oversize Packets — Displays the number of oversized packets (over 1518 octets) received on the
interface since the device was last refreshed.
• 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.
• Utilization — Displays the percentage of the interface utilized.
