RMON Statistics

The RMON Statistics screen provides access to a broad range of statistics, including a total count of different frame types and sizes passing through each port. The values displayed have been accumulated since the last sys- tem reboot.

Select the required port.

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 utiliza- tion.

Received Frames - The total number of frames (bad, broadcast, and mul- ticast) received.

Broadcast Frames - The total number of good frames received that were directed to the broadcast address. This does not include multicast packets.

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 long (excluding framing bits, but including FCS octets) and were otherwise well formed.

Fragments - The number of outbound packets that could not be trans- mitted because of errors.

CRC Errors - The total number of frames received that were less than

64 octets long (excluding framing bits, but including FCS octets) and had either an FCS or alignment error.

Jabbers - The total number of frames received that were longer than 1518 octets long (excluding framing bits, but including FCS octets) and had either an RCS or alignment error.

Collisions- The best estimate of the total number of collisions on this Ethernet segment.

64 Byte Frames - The total number of frames (including bad packets) received and transmitted that were 64 octets in length (excluding framing bits, but including FCS octets).

65-127 Byte Frames - The total number of frames (including bad pack- ets) received and transmitted where the number of octets fall within the specified range (excluding framing bits, but including FCS octets).

128-255 Byte Frames - The total number of frames (including bad pac- ets) received and transmitted where the number of octets fall within the specified range (excluding framing bits, but including FCS octets).

256-511 Byte Frames - The total number of frames (including bad pack- ets) received and transmitted where the number of octets fall within the specified range (excluding framing bits, but including FCS octets).

512-1023 Byte Frames - 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).
