This topic lists additional troubleshooting information for common components when you are using VRC integrated with PTC.
If either VRC or PTC applications are not operable, the common components might be suspect. These common components include:
Cisco IE2100 device
Tomcat
CNS security service
Cisco IE2100:
Device information is available on Cisco.com.
You must either have the CNS agent configured on the Cisco IOS device or, if the device is not CNS capable, you must have the Intelligent Modular Gateway (IMGW) enabled in the Cisco IE2100 for the device. You can set up the CNS agent manually through PTC.
You may need an http server configured on elements that you want to use in the dial plan. Refer to PTC 2.1 reference documentation located at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/ptc/2_1/index.htm
VRC pings an element using CNS event through the Cisco IE2100 device before it deploys the new configuration. VRC also gets the running configuration of the Cisco IOS device by using CNS or by using an http connection through the Cisco IE2100. If the element is inaccessible, the timeouts are long enough so that it might appear that VRC is inactive.
You can log directly in to the Cisco IE2100 device to check if the Cisco IOS device is in communication with the Cisco IE2100. The events.log on the Cisco IE2100 lists data on problems that might occur.
If you are using the Cisco IE2100 device in your network, and AAA is enabled on a device, a user with privilege level of 15 is required to bypass the enabled password prompt.
If the Cisco IOS version on your device is not event-based (for example, 12.2(2)T), the device cannot be configured for both username/password and enable password.
If the Cisco IOS version running on your device is event-based (for example, 12.2(11)T), the password combinations on the device are bypassed with the events, regardless of what is configured on the device.
Tomcat:
Is an open source component. Refer to the tomcat website for more information.
Can be restarted manually, if necessary.
CNS security service:
Relies on Data Connection Limited (DCL) LDAP server (DC-Directory).
If you have issues with the CNS security service, review the LDAP server logs.
Information for both VRC and PTC (when integrated) is in the LDAP directory as o=cisco, ou=ccnsc.
Open source tools can be used to administer LDAP server through the back door.
