282 CHAPTER 15: VIEWING STATISTICS
■ Received Packets — Displays the number of packets received on the
interface since the device was last refreshed, including bad packets,
Multicast and Broadcast packets.
■ Broadcast Packets — Displays the number of good Broadcast
packets received on the interface since the device was last refreshed.
This number does not include Multicast packets.
■ Multicast Packets — Displays the number of good Multicast packets
received on the interface since the device was last refreshed.
■ 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.
