Displaying RMON Statistics

Use the RMON Statistics screen to display k ey 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 the 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 and sizes passing through each port.

Values displayed have been accumulated since the last system reboot.

Figure 2-47. RMON Statistics

Internal Mac

Transmit Errors*

The number of frames for which transmission failed due to an

internal MAC sublayer transmit error.

Carrier Sense Errors* 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*

The number of frames for which reception failed due to an internal

MAC sublayer receive error.

* The reported values will always be zero because these statistics are not

supported by the internal chip set.
