The ifType field indicates the value in the ifType column of the MIBII ifTable that is used to identify interfaces of this type. If an interface does not have an entry in the ifTable, or if it does not use one of the ifType values identified above, then it will not be identified as a WAN interface by 3Com Network Director.

Key Considerations

Problems with In order to discover a remote site successfully, 3Com Network Director Discovering Remote must be configured with appropriate numbers of retries and timeout

Sites periods to account for the WAN links in the path to that site. If you run a Network Discovery and do not enter appropriate values for the subnets at that remote site then you may find that:

■Some or even all of the devices at the site are not discovered at all.

■Some of the devices at the site may be discovered as MAC-only devices.

■3Com Network Director may fail to retrieve full details of some or all of the devices’ features and configurations.

■3Com Network Director may be unable to correctly determine the topology of the site.

If any of these issues arise when you are discovering a remote site then you should examine the Discovery report to see if there are any errors reported for the subnets at the remote site that indicate that devices at the site stopped responding during discovery. These errors can indicate that the numbers of retries or timeout periods are set too low for that site.

In order to resolve this issue you should try to determine suitable numbers of retries and timeout periods for different request types to the devices at that site and then re-run the Network Discovery for the site using those
