Statistics

The Statistics tab contains the Interface Statistics screen, which lets you display statistics for a specified interface.

Statistics > RMON Statistics

Statistics > RMON Statistics

This screen allows you to display RMON statistics for the Ethernet port or LAG that you specify. You can also specify the rate at which the display will be refreshed.

Interface  To display statistics for an Ethernet port, select Unit No., then select the desired unit number and port from the drop-down menus. To display statistics for a LAG, select LAG and then select the desired LAG from the drop- down menu.

Refresh Rate  Select the rate at which to refresh the statistics display. The values are 15 sec, 30 sec, 60 sec, and No Refresh (default).

Drop Events  Displays the number of dropped events that have occurred on the interface since the device was last refreshed.

Received Bytes (Octets)  Displays the number of octets received on the interface since the device was last refreshed. This number includes bad packets and FCS octets, but excludes framing bits.

Received Packets  Displays the number of packets received on the interface, including bad packets, Multicast and broadcast packets, since the device was last refreshed.

Broadcast Packets Received  Displays the number of good broadcast packets received on the interface since the device was last refreshed. This number does not include Multicast packets.

Multicast Packets Received  Displays the number of good Multicast packets received on the interface since the device was last refreshed.

CRC & Align Errors  Displays the number of CRC and Align errors that have occurred on the interface since the device was last refreshed.

Undersize Packets  Displays the number of undersized packets (less than 64 octets) received on the interface since the device was last refreshed.

Oversize Packets  Displays the number of oversized packets (over 1518 octets) received on the interface since the device was last refreshed.

Fragments  Displays the number of fragments (packets with less than 64 octets, excluding framing bits, but including FCS octets) received on the interface since the device was last refreshed.

Jabbers  Displays the total number of received packets that were longer than 1518 octets. This number excludes frame bits, but includes FCS octets that had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral octet (Alignment Error) number. The field range to detect jabbers is between 20 ms and 150 ms.

Collisions  Displays the number of collisions received on the interface since the device was last refreshed.

Frames of xx Bytes  Number of xx-byte frames received on the interface since the device was last refreshed.

Clear Counters  Click Clear Counters to reset all the counters on this screen to zero.

Refresh Now  Click Refresh Now to refresh the display immediately with the latest information.

Statistics > RMON History

The RMON History screen contains information about samples of data taken from ports. For example, the samples may include interface definitions or polling periods.
