How Can Discovery Be Disabled?
You cannot completely shut off discovery. CWSI Campus was built on a real-time data model that relies
upon discovery data.
You can set the discovery interval to an extremely large number so that discovery occurs only when the
ANI server starts or when you manually discover the network.
How Can Devices Be Deleted?
If CWSI Campus has discovered a device that you do not want displayed on the map, you cannot delete
this device. The following solutions are available:
•
Remove the links to the device, and drag the device icon to a remote portion of the map so that it
does not appear in the main map window.
This solution works well if the device is in your network, but you do not want to display it on the
CWSI Campus map.
•
Replace the CWSI Campus database and force an initial discovery.
This solution works best for erroneously discovered devices that are not really in your network, or
if you have removed a device since the initial discovery.
Why Does the ATM Network Appear as a Cloud?
If CWSI Campus cannot correlate the ATM link information, the ATM network appears as a ATM cloud
on the CWSI Campus map. Possible causes and their solutions include these:
ILMI is not active on the ATM network.
•
Verify that ILMI is active on the ATM devices in your network.
-
Default ATM-VLAN has not been properly configured.
•
You did not use an ATM device as a seed for discovery.
•
ILMI is not returning the correct IP information.
•
ILMI does not automatically update when IP addresses are changed. Reset the LightStream
1010 ATM switch to clear out the ILMI table.
-
The ILMI entries are not up-to-date between any given ATM link.
•
Verify that the ILMI entries are up-to-date and that they are consistent.
-
Your LANE modules have older software image versions.
•
If any devices have one or more LANE modules and are running software image versions that
are older than 3.2(7) or the 11.3(3a)WA4(5), the ATM network will not be discovered properly.
Use software image versions 3.2(7) or 11.3(3a)WA4(6) or later.

Why Do Some Ethernet Links Not Include Speed?
On some devices (typically unknown devices), CWSI Campus can retrieve only the media table from the
IF table RFC 1213 MIB ifType. In these cases, the link is displayed as Ethernet. For most devices, CWSI
Campus reads the enterprise-specific MIBs, which contain more detailed port-type information.
Therefore, 10 M and 100 M are displayed on the map.
