864Appendix E: REPORT EXAMPLES

The following devices returned invalid port information

During the sizing stage the application attempts to determine which ports are enabled and have a link present since it is only those that can take an active roll in the topology. For some third party devices it may fail to obtain any valid ports and this message will be logged. Also, for the CoreBuilder 9000 and Switch 4007 the application does not support the scenario where the management port is the port directly connected to the network. If this is the only connected port then this message will be logged.

The exact position of the following devices could not be determined

This is really just a statement of fact. It is likely to be due a problem that has occurred earlier such as losing communication with one of the switches, or possibly if no MAC addresses were obtained for the device.

3Com Network Director was unable to write to the following devices, in order to get them to perform operations that could lead to a more accurate topology detection.

This is a failure to instruct a device to perform a remote poll. To do this 3Com Network Director performs a write operation using the write community string. If the write community string is incorrect it is likely that the attempt will time out.

The configuration of the following devices is not supported by 3Com Network Director

This was originally added when support was included for the switch 4007. Because it was not possible to distinguish between it and other CoreBuilder 9000 devices, if an non-7-slot CoreBuilder 9000 was encountered this error would be logged. This should no longer occur as this restriction has been removed.

The following devices have support for the Spanning Tree Protocol enabled. Links connected to these devices may in the future be blocked by the Spanning Tree Protocol. 3Com Network Director may not be able to detect this occurring.

The following devices have one or more ports that could not be included in the network topology
