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. 2.
