Broadcast Packets — The number of good Broadcast packets received during the sampling interval.
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 of
64-1518 octets, a bad Frame Check Sequence (FCS), and with an integral number of octets, or a
bad FCS with a non-integral number of octets.
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 1518 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 total number of packets received that were longer than 1518 octets (excluding
framing bits, but including FCS octets), and had either a bad Frame Check Sequence (FCS) with
an integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets
(Alignment Error). The allowed range to detect jabber is between 20 ms and 150 ms.
Collisions — Estimates the total number of packet collisions that occurred during the sampling
session. Collisions are detected when repeater ports detect two or more stations transmit
simultaneously.
Utilization — Estimates the main physical layer network usage on an interface during the session
sampling. The value is reflected in percents.
