5-10 Repeater Statistics

To access the board-level Performance Graph windows:

1. Click on the appropriate Module Index to display the Module menu.

2. Select the appropriate repeater channel (A - H) to reveal the board-level

Repeater menu.

3. Click on Performance Graph. The board-level Performance Graph window

will appear.

To access the port-level Performance Graph windows:

1. Click on the appropriate Port in the Chassis View display; the Port menu will

appear.

2. Click on Performance Graph. The port-level Performance Graph window will

appear.

The Board and Port Performance Graph windows are similar to the Repeater

Performance Graph window displayed in Figure 5-4, except that they display

statistics applicable to the board or port level.

For each chosen statistic, Performance Graphs display both average and peak

activity, as well as the date and time the peak values were recorded; average

values are also displayed graphically.

The Average statistics are updated every two seconds, as averaged over the

previous four two-second intervals; the graphical display also updates at

two-second intervals. For the Þrst 60 seconds of graphing, you will note the graph

lines extending as each intervalÕs data is added to the graph. Once the Þrst 60

seconds has passed, the newest data is added at the right edge of the graph, and

the oldest data is scrolled off to the left.

Each Performance Graph window allows you to graph the following statistical

variables:

Percent Load (Green)

Percent Load Reßects the network load generated by the selected

repeater, board, or port, compared to the theoretical

maximum load (10 Mbits/s) of an Ethernet network.

Active Users The number of users transmitting or receiving on the

selected repeater, board, or port, as determined by the

current number of Ethernet (MAC) addresses stored in

each portÕs Source Address Table.

NOTE

In accordance with Year 2000 compliance requirements, SPECTRUM Element Manager

now displays and allows you to set all dates with four-digit year values.
