•
Multicast Packets
— The number of good multicast packets received during the sampling interval.
•
CRC Align Errors
— The number of packets received during the sampling session with a length
64-1632 octets. However, the packets has a bad packet Check Sequence (FCS) with an integral
number of octets or a bad FCS with a non-integral number.
•
Undersize Packets
— The number of packets received less than 64 octets long during the
sampling session.
•
Oversize Packets
— The number of packets received more than 1632 octets long during the sampling
session.
•
Fragments
— The number of packets received less than 64 octets long and had a FCS during the
sampling session.
•
Jabbers
— The number of packets received more than 1632 octets long and had a FCS during the
sampling session.
•
Collisions
— Estimates the total number of packet collision that occurred during the sampling
session. Collision are detected when repeater port detects two or more stations transmit
simultaneously.
•
