Accessing Hub Features

Configuring Your Device

If the device you selected is not manageable by browser, you can only manage it from the HP TopTools Management Workstation. To obtain generic SNMP information about non-HP devices, select Properties from the Actions button menu. To establish a telnet session to this device (if the device supports telnet), select Telnet from the Actions button menu.

Figure 12-6. Hub Device View

You can enable and disable individual ports (click on the port to select it), or click on the Select All Ports button to enable or disable all the ports of a device in one step.

Click on the link “meaning behind the port icons” above the Device View to view the port indicator legend.

Fault Detection

The automatic fault detection feature protects your network from failing because of problems such as network loops, defective cables, transceivers and faulty network interface cards. The Fault Detection page lets you set the sensitivity and actions that occur when a fault is detected on a port in your network. For hubs, you can set the sensitivity for logging network problems and disabling ports. The sensitivity settings are:

High Sensitivity: The device will act when a network problem of any severity occurs. Network problems are automatically detected and entered into the Alert Log.
