Overview of Hub

1	Overview of Hub
	Management

Hubs themselves are rarely the cause of problems on the network. However, since hubs are the center point for many devices on the network, it’s a good place to start looking for problems.

There are four categories of management tasks:

• Configuring the hub or stack of hubs. This includes setting the IP configuration, naming the hubs, and disabling individual ports.

• Monitoring traffic. This helps to plan network expansion or make segmenting decisions.

• Finding malfunctioning devices such as LAN adapters in PCs.

• Finding wiring problems between an attached device and the hub.

There are several methods for managing hubs. You can use any combination.

• Manage with the onboard LCD or Console Manager. This method works best for initial setup or when the network goes down and you can’t access the hub with an SNMP application.

• Manage with Intel Device View for Web or LANDesk® Network Manager. These SNMP applications are tailored for Intel products and show a graphical representation of the hub.

• Manage with any other SNMP-compliant application. If you already use an SNMP application, you can manage hubs by compiling the hub’s MIB files into that application. File locations are listed on page 51.
