can be discovered. See “Specify Subnets Pane” on page 111 for details of how to do this.

■It is possible to configure the numbers of retries and timeout periods to use for each subnet being discovered. See “Specifying Retries and Timeout Periods in the Network Discovery Wizard” on page 700 for details of how to do this.

■If automatic monitoring mode is not being used then the monitoring mode to use for the subnets being discovered can be specified. See “Specifying Monitoring Mode in the Discovery Wizard” on page 302 for details of how to do this.

■The types of devices to discover can be restricted to only core devices or only IP devices. See “Discovery Options Pane” on page 122 for details of how to do this.

The appropriate use of the numbers of retries and timeout periods in a multi-site network are discussed in “Configuring Retries and Timeout Periods” on page 694, while the appropriate use of monitoring modes in a multi-site network is discussed in “Configuring Monitoring Modes and Poll Rates” on page 705.

The remaining two options allow you to filter which devices are discovered by the network discovery process by restricting the Network Discovery process to certain important subnets, ranges on those subnets that contain important devices and devices of a specific type.

Controlling the Network Discovery process in this manner reduces the total number of devices represented in the map.

Devices containing large numbers of devices can be complex to navigate. By filtering out devices that you are not interested in monitoring or managing on a day-to-day basis, or that are not your direct responsibility, you can simplify navigation.

In addition, 3Com Network Director has a limit of 5,000 devices within a single map. If you have a large network then it may not be possible to display all of the important devices in a single map unless you filter out those devices that are less important to you.
