•
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.
