Managing Ethernet MicroLAN Switches

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

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 first 60 seconds of graphing, you will note the graph lines extending as each interval’s data is added to the graph. Once the first 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

Reflects 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 port’s Source Address Table.

Nothing

The Percent Load function is not currently measuring

 

any statistics.

Frames (Blue)

 

Frames

The total number of packets (both good and error)

 

processed by the selected repeater, board, or port.

Nothing

The Frames scale is not currently measuring any

 

statistics.

Total Errors (Red)

 

Total Errors

The total number of errors of any kind processed by the

 

selected repeater, board, or port.

Collisions

The total number of collisions (combined transmit and

 

receive) detected by the selected repeater, board, or port.

CRC Errors

The total number of packets with CRC (Cyclical

 

Redundancy Check) errors that the selected repeater,

 

board, or port has received from the network.
