HP Network Direr Software Products manual Initial Map Creation

Components 133

Note that the analysis is always performed on the whole of your map, not just the recent additions. You can force a new version of the report to be generated from the Tools > Reports dialog box, although generally there should be little need to do this since it should be the same as the one from the most recent discovery, unless you have manually changed the map.

See “Report Examples” on page 861 for a full list of the misconfigurations that may be detected, and possible suggested optimizations.

The Changes Report When a rediscovery is performed on a map that already contains some devices, 3Com Network Director compares the contents of the current map with the newly acquired information. Any differences it finds are used to populate the Changes report. Typical changes are, a device has changed configuration (e.g. a new unit has been added), or a device has been moved and as a result its link properties have changed.

The Changes report will not produce information on IP address changes to avoid large reports being generated on networks using DHCP. For a similar reason, the Changes report will not produce information on devices that appear between network discoveries as users log in and log out due to the Network Login support. See “Network Login” on page 227.

Also see “Report Examples” on page 861 for a full list of the changes that may be detected.

The Displayed Map After a discovery operation has completed and you have dismissed the Network Discovery Summary dialog box, the map and tree views will be updated to reflect the new information.

Initial Map Creation

After the first discovery on a new map, 3Com Network Director simply adds all the new devices to the map as it feels appropriate. The map is initially shown at the top-level map of the Grouped Network View. This map shows all the subnets it has detected and any routers it discovered on those subnets. It also includes the additional subnets that were detected, when communicating with the routers, that weren’t part of the list of subnets to discover. These are shown as undiscovered subnets. 3Com Network Director attempts to arrange (layout) the devices and subnets so that they do not overlap. For information on using the map,
