3.7.1.2.Displaying RMON Statistics

Use the RMON Statistics screen to display key statistics for each port 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.

Parameter Description

Drop Events The total number of events in which packets were dropped

due to lack of resources.

Received Bytes Total number of bytes of data received on the network. This

statistic can be used as a reasonable indication of Ethernet

utilization.

Received Frames The total number of frames (bad, broadcast and multicast)

received.

Broadcast Frames The total number of good frames received that were directed

to the broadcast address. Note that this does not include

multicast packets.

Multicast Frames The total number of good frames received that were directed

to this multicast address.

CRC / Alignment Errors The number of CRC / alignment errors (FCS or alignment

errors).

Undersize Frames The total number of frames received that were less than 64

octets long (excluding framing bits, but including FCS octets)

and were otherwise well formed.
