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.
