RMON Statistics
Use the RMON Statistics screen to 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 provides 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.
Late Collisions
The number of times that a collision is detected later than 512 bit-
times into the transmission of a packet.
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.
Carder Sense Errors
1
The number of times that the carrier sense condition was lost or
never asserted when attempting to transmit a frame.

frame size.
Internal Mac Receive
