AutoDiscovery uses the starting IP address you supply in the AutoDiscovery Setup dialog box to find other devices. AutoDiscovery contacts that device, finds what devices it knows of, contacts them, and so on.
However, because network devices keep track of the address of other devices for only a short while, a device that isn't centrally located or doesn't get much traffic may not be a useful starting address. You can try the following:
- Add the IP addresses of several other devices that you know are active on your network.
- Turn off the Limit to Starting IP Class Networks. This gives the discovery process a broader reach.
- Exit Network Manager, open the SNMPC.INI file in Notepad, and change the NumSequentialSteps setting in the [AutoDiscovery] section to 5 or 10. You can use sequential polling to discover more nodes by setting this option in the [AutoDiscovery] section of SNMPC.INI:
- NumSequentialSteps=5
In this case AutoDiscovery polls each node with an IP address up to 5 less than and 5 more than any discovered node.
WARNING: Do not set this number too high. Also, do not use sequential polling with the Distinct TCP/IP stack.
