This chapter provides troubleshooting hints for problems you may encounter when installing and using Workgroup Director:
If you encounter problems starting Workgroup Director, make sure the floppy disk you used during installation matches the workstation operating system version and windowing environment. Following are examples of error messages that may appear:
This section provides solutions to problems that may arise with the concentrator or switch, such as the following:
No display of the concentrator or switch in Workgroup Director indicates a communication problem. Either the connection from your station to the concentrator is disrupted, or the concentrator or switch is not functioning.
Communication problems could be due to incorrect IP addressing or improper routing. First, check to see that the SNMP addressing and route commands are set correctly by performing the following steps:
If these addresses and routes are configured properly, but the LEDs are still not lit, thoroughly check the connections between the workstation and the concentrator.
If you suspect that the concentrator is down, you can use the ping command to see if it answers. If the concentrator IP address, route command, the workstation hosts file, and the NIS database are configured properly, you should be able to ping. A negative ping response may mean that the concentrator is not functioning, or the IP configuration is incorrect.
It is possible to communicate with the concentrator by using the ping command, but still not be able to use Workgroup Director. If your ping response is slow (more than 2 seconds), or if you are routing through several networks, use the Workgroup Director timeout
(
-t) option to increase the length of time to wait for an SNMP response. For instructions on how to use the timeout option, refer to Chapter 2, "Installing Workgroup Director on a SPARCstation." You can also change the timeout parameter from the Properties menu.
Also check to see that you are using the correct community string. If public is not designated as a read community string, use the community string (-c,
-C) options to change the default community string sent in the SNMP requests. You can also change the Community String parameter by using the Properties menu.
For instructions on how to diagnose concentrator hardware problems, refer to the troubleshooting chapter in your concentrator user guide.
This section provides solutions to problems that may arise with the adapter, such as the following:
Communication problems could be due to incorrect IP addressing or improper routing. First, check to see that the IP addressing and route commands are set correctly by performing the following steps:
/etc/hosts file for both the target workstation and the workstation running the Workgroup Director.
If these addresses, host names, and routes are configured properly, you should be able to ping from the Workgroup Director workstation to the target workstation.
If you are able to ping the target workstation, but Workgroup Director still does not display the adapter, there may be a problem with the SNMP configuration. Follow these steps to check the SNMP configuration:
If Workgroup Director still does not display the adapter, it may be due to a missing SNMP agent or the wrong SNMP agent running on the target workstation. Follow these steps to check the SNMP agent:
The adapter is visible in Workgroup Director only if the Cisco SNMP agent is running on the target workstation. If it is not, install the Cisco SNMP agent from the adapter installation disk.
