Cabletron Systems 7000 manual Viewing Fddi Statistics, Packets Transmitted Transmit only

The SmartSwitch 7000 Chassis View

Packets Transmitted (Transmit only)

Displays the number of packets transmitted by this interface.

Making Sense of Detail Statistics

The statistics available in this window can give you an idea of how an interface is performing; by using the statistics in a few simple calculations, itÕs also possible to get a sense of an interfaceÕs activity level:

To calculate the percentage of input errors:

Received Errors /Packets Received

To calculate the percentage of output errors:

Transmitted Errors /Packets Transmitted

To calculate the total number of inbound and outbound discards:

Received Discards + Transmitted Discards

To calculate the percentage of inbound packets that were discarded:

Received Discards /Packets Received

To calculate the percentage of outbound packets that were discarded:

Transmit Discards /Packets Transmitted

NOTE

Unlike the Interface Detail window, which this window replaces, the Interface Statistics window does not offer Disable or Test options. These options are available in the Interface Group window, which can be accessed via the System Group window (select System Group... from the Device menu). Refer to your Generic SNMP UserÕs Guide for further information on the System Group and Interface Group windows.

Viewing FDDI Statistics

The FDDI Statistics window, Figure 2-9,provides basic information concerning the ring networks supported by the SmartSwitch 7000Õs SMT entities Ñ including bandwidth utilization expressed in terms of frames/second (current) and kilobytes/second (both current and peak experienced since last reset), and current utilization as a percentage of theoretical maximum.

A timer interval lets you set the interval at which you want the SmartSwitch 7000Õs installed FDDI NIMs polled for this information.

To access the FDDI Statistics window:

1.In the Chassis View, click on Device.

2.Drag down to FDDI Statistics... and release. The FDDI Statistics window will appear.
