Troubleshooting

Use these troubleshooting tips to assist you when the results in the UserTracking application are not what you expect.

The following problems are discussed:

When you select Action>Configure TFTP Servers, you might not see any domains displayed in the Select Domain list in the upper left-hand corner of the window. This situation might occur for the following reasons:

ANI did not find any domains to display.

The VMPS information already loaded in the VMPS server is incorrectly configured. For example, the VTP domain specified in the VMPS configuration information is not the same as the VTP domain in which the switch is located. See Chapter 3, "Managing VMPS Servers and Dynamic VLANs" for more information.
ANI is unable to obtain the TFTP information, typically because of an SNMP timeout. ANI does not try again to reload this information. If this situation occurs, you must stop the ANI process and restart it. See the "How Do I Restart the ANI Process?" section for instructions on how to do this.

Why is UserTracking Unable to Find Any Entries?

If UserTracking does not find any entries, the following possibilities exist:

No end-user nodes are connected, or they are inactive. Enable ping sweeps in UserTracking and perform a UserTracking discovery by clicking Action>Discover>End-User Nodes.
ANI may not have discovered devices to which end-user nodes are connected. Check the CWSI Topology for the missing devices, make sure that CDP and SNMP are enabled on the devices, and rediscover the topology map.

How Do I Ping Class A and Class B Addressed Subnets?

Ping sweeps are performed based on how many hosts are possible in a subnet. If the number is less than or equal to 256, then ping sweeps will be performed in that subnet. If the number of hosts in a subnet is greater than 256, then ping sweeps will not be performed. However, if ping sweeps are not performed, during a major acquisition information will still be obtained from the router or switch mapping tables.

What User Name and Password Do I Need For TFTP?

Although UserTracking stores the VMPS information on a TFTP server, it uses FTP to transfer the information to the server. You must configure an account for FTP access by UserTracking. If you are using Windows NT, Microsoft IIS 2.0 installs an FTP daemon that you can use with UserTracking. Create a new user with the name cisco and the password cwsi. Make sure that the password never expires and the new user has administrative capabilities. Enter the new user name and password in the TFTP Configuration window and click Apply. See the "Configuring TFTP Information" section in Chapter 3, "Managing VMPS Servers and Dynamic VLANs" for more information.

How Do I Restart the ANI Process?

To restart the ANI process, open a command prompt or shell window. Enter stopcwsiserver to stop the CWSI server processes. When the prompt returns, all the daemons have been stopped. To restart the processes, enter startcwsiserver and wait until the prompt returns.

For more detailed information about the ANI process, see the Getting Started with CWSI Campus publication.
