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. |
Oversize Frames | The total number of frames received that were longer than 1518 |
| octets(excluding framing bits, but including FCS octets) and were |
| otherwise well formed. |
Fragments | The total number of frames received that were less than 64 octets in |
| length(excluding framing bits, but including FCS octets) and contained |
| either an FCS or alignment error. |
Jabbers | The total number of frames received that were longer than 1518 octets |
| (excluding framing bits, but including FCS octets), and contained either |
| an FCS or alignment error. |
Collisions
64 Byte Frames
The best estimate of the total number of collisions on this Ethernet segment.
The total number of frames (including bad packets) received and transmitted that were 64 octets in length (excluding framing bits but including FCS octets).
The total number of frames (including bad packets) received and transmitted where the number of octets fall within the specified range (excluding framing bits but including FCS octets).
