132CHAPTER 4: DISCOVERING THE NETWORK

these relate to 3Com Network Director not being able to retrieve all the information it requires to accurately depict your network. For example it may have lost communication with some of the devices during the discovery process.

The report is divided into two main sections:

Discovery

This section lists any problems encountered in the detecting devices part of the discovery process. There is a separate sub-section for each subnet that was discovered. Within each subnet section the report lists the problems encountered and the devices to which the problems apply. For instance, it may have failed to determine the write community string for a device.

Topology

This section lists any problems encountered in the discovering links part of the discovery process. There is a separate sub-section for each multinet that it attempted to determine the topology of. Within each multinet section the report lists the problems encountered and the devices to which the problems apply. For instance, it may have lost communication with a device when reading the bridge FDB tables.

Each of the problems listed within the report has a severity level associated with it, either Warning or Error. For instance, failing to determine the write community string is considered a warning, since, although it is required for other areas of 3Com Network Director it is not essential for discovery. However, a loss of communication is considered an error since it is likely to adversely affect how 3Com Network Director depicts your network.

See “Discovery Report Errors and Warnings” on page 144 for a full list of the possible errors and warnings

The When a discovery operation is complete, 3Com Network Director Misconfigurations analyses the results in order to establish if any devices have been and Optimizations misconfigured, or if any improvements could be made to the

Report configuration of your network in order to improve its efficiency. Both the misconfigurations and improvements (optimizations) are included in the same report, but in separate sections. If there are no misconfigurations or if there are no optimizations then the entire corresponding section will be omitted from the report.
