•Octets - Number of octets passing through this port.

•Multiple Collisions - A count of successfully transmitted frames for which transmission is inhibited by more than one collision.

•Late Collisions - The number of times that a collision is detected later than 512 bit-times into the transmission of a packet.

•Carrier Sense Errors - The number of times that the carrier sense con- dition was lost or never asserted when attempting to transmit a frame.

•Fragments - The total number of frames received that were less than 64 octets in length (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 (excluding framing bits, but including FCS octets), and had either an FCS or alignment error.

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 system reboot.

Select the required port.

•Drop Events - The total number of events in which packets were dropped due to lack of resources.

•Bytes - Total number of bytes of data received on the network. This statistic can be used as a reasonable indication of Ethernet utiliza- tion.

•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. This does not include multicast packets.

•Multicast Frames - The total number of multicast frames.

•CRC/Alignment Errors - The number of CRC/alignment errors (FCS or alignment errors).
