Statistics > RMON Statistics
The RMON Statistics screen contains fields for viewing
information about device utilization and errors that
occurred on the device.
Statistics > RMON Statistics
Interface Indicates the device for which statistics are
displayed. The possible field values are:
Port • Defines the specific port for which RMON
statistics are displayed.
LAG • Defines the specific LAG for which RMON
statistics are displayed.
Refresh Rate Defines the amount of time that passes
before the interface statistics are refreshed. The possible
field values are:
No Refresh • Indicates that the RMON statistics are not
refreshed.
15 Sec • Indicates that the RMON statistics are refreshed
every 15 seconds.
30 Sec • Indicates that the RMON statistics are refreshed
every 30 seconds.
60 Sec • Indicates that the RMON statistics are refreshed
every 60 seconds.
Drop Events Displays the number of dropped events
that have occurred on the interface since the device was
last refreshed.
Received Bytes (Octets) Displays the number of octets
received on the interface since the device was last
refreshed. This number includes bad packets and Frame
Check Sequence (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 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
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 20–150 ms.
Collisions Displays the number of collisions received on
the interface since the device was last refreshed.
Frames of xx Bytes Number of xx-byte frames received
on the interface since the device was last refreshed.
Clear Counters button This option will reset all of the
statistic counts.
Refresh Now button Use this option to refresh the
statistics that are displayed on the page.
