RMON Statistics

RMON Statistics display key statistics for each port or media module
from RMON group 1. (RMON groups 2, 3 and 9 can only be accessed
using SNMP management software.) The following screen displays
overall statistics on traffic passing through each port. RMON statistics
provide access to a broad range of statistics, including a total count of
different frame types passing through each port. Values displayed have
been accumulated since the last system reboot.

Excessive
Collisions

1

The number of frames for which transmission failed due to excessive
collisions.

Internal Mac
Transmit Errors

1

The number of frames for which transmission failed due to an internal
MAC sublayer transmit error.

Carrier Sense
Errors

1

The number of times that the carrier sense condition was lost or never
asserted when attempting to transmit a frame.

Frames Too Long

The number of frames received that exceed the maximum permitted
frame size.

Internal Mac
Receive Errors

1

The number of frames for which reception failed due to an internal MAC
sublayer receive error.
