- 60 Sec — Indicates that the RMON statistics are refreshed every 60
seconds.
• Received Bytes (Octets) — Displays the number of octets received on the
interface since the page was last refreshed. This number includes bad packets
and FCS octets, but excludes framing bits.
• Dropped Events — Displays the number packets that were dropped.
• Received Packets — Displays the number of packets received on the interface,
including bad packets, Multicast and broadcast packets, since the page was
last refreshed.
• Broadcast Packets Received — Displays the number of good broadcast
packets received on the interface since the page 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 page was last refreshed.
• CRC & Align Errors — Displays the number of CRC and Align errors that have
occurred on the interface since the page was last refreshed.
• Undersize Packets — Displays the number of undersized packets (less than 64
octets) received on the interface since the page was last refreshed.
• Oversize Packets— Displays the number of oversized packets (over 1518
octets) received on the interface since the page 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 page 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 page was last refreshed.
• Frames of xx Bytes — Number of frames containing the specified number of
bytes that were received on the interface since the page was last refreshed.
