Statistical Display for System Performance
Utilization - (Utilization%) The statistical indicators show the percentage of valid data passing through all ports compared to overall network bandwidth (updated every
0.5seconds). There are 5 LEDs representing the percentage of network utilization. The corresponding LEDs light up to show that the utilization of LAN bandwidth has reached this level. When active, these LEDs behave like a stereo’s equalizer display.
For example, if network utilization reaches 1%, the LED labeled 1% will light up. However, if network utilization rises above 1% (e.g., 30%), the LED labeled 30 and all the other LEDs before it (i.e., 1, 5 and 15) will also light up in rapid succession. These indicators monitor the share of valid network frames handled by the hub within a 100 Mbps bandwidth. They provide a quick way to monitor the current traffic load relative to the network’s capacity.
Collision - (Collision%)- The statistical indicators show the percentage of packet collisions occurring out of the total packets transmitted by the hub. Collisions occur when two or more devices connected to a hub attempt to transmit data simultaneously on the network. When a collision occurs, devices pause and then
The Collision LEDs assist the network manager in monitoring the percentage of packet collisions occurring relative to the total packets transmitted by the hub. When collisions reach a level marked on the front panel display, the correspond- ing LED lights up. For example, if packet collisions reach 1%, the LED labeled 1% will light up. However, if collisions go beyond 1% (e.g., 15%), the LED labeled 15+% and all the other LEDs before it (i.e., 1, 3, 5 and 10) also light up in rapid succession.
