This chapter provides the following sections on how to troubleshoot any problems you might encounter when managing your devices or when using CiscoWorks Windows. It also includes information on how to report unresolved problems to Cisco Systems:
This section describes actions you can take to troubleshoot your device:
Read your Cisco IOS release notes or check CCO for the latest bug information for the version of Cisco IOS your device is running.
Perform any of the following tasks in CiscoView to isolate the cause of a problem:
CiscoView displays the following SNMP error messages resulting from failed command requests in the Status Bar message area (Table 6-1).
You can no longer reach the device in the time specified in the CiscoView Properties window.
The request you made cannot fit into a single packet. Generally, CiscoView splits requests for physical view status until the device can respond. In certain cases, CiscoView assumes that if an agent times out on 20 or more variables, the agent might not be able to respond because the request is too big; it splits the request and resends it. Check that the MTU size on the SNMP interface is as large as possible so that CiscoView does not waste bandwidth by sending more than one request.
A collective message name for problems that do not have a unique error message.
A request for a variable was sent to a variable that is not accessible. This occurs if you are not using the correct community string.
The agent did not respond within the time interval specified by the timeout/retries field in the CiscoView Properties window. This can also indicate the use of an incorrect community string.
This section describes using release notes and provides troubleshooting tips for CiscoWorks Windows applications in the following sections.
For CiscoWorks Windows release-specific installation information, double-click on the ReadmeFile icon in your CiscoWorks Windows program group or folder. For detailed release information and caveats, refer to the CiscoWorks Windows Release Notes or the CiscoView Release Notes shipped with the product or on CCO. They present the known problems you might encounter and possible workarounds for them.
Table 6-2 provides Configuration Builder troubleshooting procedures.
Configuration Builder generates a path error.
The TCP/IP option is grayed-out in Learn and Send dialog boxes.
In Configuration Builder, a device cannot be connected through TCP/IP.
Connect to the router using the Telnet option of your TCP/IP software or the Telnet supplied with Configuration Builder. If this fails, there might be a problem on your network. Refer to the documentation for your TCP/IP stack.
Long delay (in Learn and Send dialog boxes) in connecting to the router.
The connection times out, or there is a long delay on a serial connection.
Configuration Builder cannot communicate with the router if the router is in ROM monitor mode.
If the configuration register on your router is set to boot to ROM monitor mode, check your router documentation to change the default boot mode.
Configuration Builder menus are missing.
Configuration Builder does not generate configuration commands or generates them in the wrong order.
Device does not display Configuration Builder icon.
Device or Cisco IOS is not supported. Check the release note for more information.
Configuration Builder hangs if it is running on a Pentium-based machine with a peripheral component interface (PCI) bus and a 16550 Universal Asynchronous Receiver Transmitter (UART) chip.
If you are running Microsoft Windows 3.1, do the following:
If you are running MS Windows NT, do the following:
If you are running MS Windows for Workgroups, do the following:
For CiscoWorks Windows release-specific information, double-click on the ReadmeFile icon in your CiscoWorks Windows program group. For additional release information, refer to the release notes. Application-specific caveats are grouped under "Show Commands."
For CiscoWorks Windows release-specific information, double-click on the ReadmeFile icon in your CiscoWorks Windows program group. For additional release information, refer to the release notes. Application-specific caveats are grouped under "Health Monitor."
For CiscoWorks Windows release-specific information, double-click on the ReadmeFile icon in your CiscoWorks Windows program group. For additional release information, refer to the CiscoView release notes. Application-specific information is grouped under "CiscoView."
CiscoView opens each device in a separate window by default. On large networks, this can consume too much RAM and slow performance. To decrease the use of RAM for separate windows, you can choose to open devices in the same window by changing operating characteristics. Select Options>Properties. Choose Same Window in the Launch CiscoView in: option.
If CiscoView fails to display a device, the following message appears:
This message indicates one of the following conditions:
If you receive an error message, try to resolve the error by following the recommended action. Check for any release-specific information that might apply to a problem by opening the ReadmeFile icon in your CiscoWorks Windows program group.
1. To help Cisco Support personnel solve any problems you encountered using CiscoWorks Windows, be prepared to:
2. If possible, try to reproduce the problem and explain the steps that allow you to reproduce the problem.
3. Provide information for the platform on which you are running CiscoWorks Windows:
