• 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.
