Troubleshooting CiscoView
This subsection provides the following information on how to troubleshoot any problems that you might
encounter when using CiscoView application and how to identify device problems using CiscoView.
The Cvinstall.cshrc and the Cvinstall.sh Files and System Performance Issue
The CVinstall.cshrc and the CVinstall.sh files automatically set all environmental variables required for
CiscoView. If there are errors starting CiscoView, source one of these files.
CiscoView opens each device in a separate window, by default. On large networks, this can consume too
much RAM and slow performance. To decrease RAM use, you can open devices in the same window by
changing operating characteristics. Select Options; Properties. Choose Same Window in the Launch
CiscoView In option.
Also, multiple sessions of CiscoView might degrade system performance because of the use of X
resources. Reduce the number of sessions running on an X server by selecting the option Same Window
in Options; Properties. This causes successive invocations of CiscoView on an X server to reuse a single
session.
Fixing Display Problems
If CiscoView fails to display a device, the following message appears:
“<hostname>: unmanageable”
This message suggests one of the following conditions:
•
The SNMP agent is not running on the device, although the device is accessible from the
management session.
-
You should be able to
ping
the device from the management session.
•
You entered an incorrect community string.
-
To re-enter a community string, select Options; Properties.
•
The management station cannot reach and successfully
ping
the device.
-
Check your device package and compare the date with the CCO device package version.
Upgrade your device package to the latest version, if required.
•
You encountered an unsupported card error.
-
CiscoView displays the “Unsupported Card” or “Unknown Card” error messages instead of
displaying the contents of the card when a device package does not support the card. You might
have to contact CCO and check the upgrade planner for the device package. If the device
package is supposed to support the card, try upgrading the device package to the latest version
from CCO.
•
You received the error message: “Can't read DD(...) not set.”
-
CiscoView generates this error message when any of the following conditions are true:
•
The IOS version is not supported by the device package.
•
The physical device might not contain a card component, or it might not have been configured
properly.
•
The IOS may not have the feature that supports the card. In this case, you might have to upgrade the
IOS to the proper version.
