202 CHAPTER 17: VIEWING STATISTICS
■ Received Bytes (Octets) — Displays the number of octets received
on the interface since the device was last refreshed. This number
includes bad packets and FCS octets, but excludes framing bits.
■ Received Packets — Displays the number of packets received on the
interface, including bad packets, Multicast and broadcast packets,
since the device was last refreshed.
■ Broadcast Packets Received — 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 Received — 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
9216 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 9216 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.
■ Frames of 64 Bytes — Displays the number of 64-byte frames
received on the interface since the device was last refreshed.
■ Frames of 65 to 127 Bytes — Displays the number of 65 to 127 byte
frames received on the interface since the device was last refreshed.
