Managed 24-Port with Dual Gigabit Switch

• 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).

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).
