Auditing Problems
f.If you feel that the command is incorrect and should be changed, contact Cisco Support for help.
g.If the command is correct, press the corresponding router configuration button. The router configuration on which the auditing was performed is shown.
h.Check the configuration command line in the configlet (the line that is apparently missing or incorrect as discovered by the audit) and see if the command line is present in the router.
i.If it is removed or absent or incorrectly changed in the router, redeploy the service request to get the corrections sent to the router.
j.However, if the configlet seems correct and the configuration commands are present in the router, call Cisco Support for assistance.
k.You can continue troubleshooting by selecting Show Processed Config Text. This presents the configuration file of the model router.
l.Check whether that command is also present in the configuration of the model router.
m.If it is absent or incorrectly modeled, be sure to inform Cisco Support.
2.Question: I have a service request in two VPNs called Red and Blue. I ran an audit, but I don’t find my service request listed in the audit reports for the Red VPN.
Answer: The audit is for a service request that may or may not be in multiple VPNs. However, MPLS VPN Solution runs an Audit VPN by VPN in alphabetical order. In case a service request is in multiple VPNs, the software audits the service request only once. This takes place in the VPN that comes up first in the alphabetical sequence, which in this case, is Blue. The software does not audit the same service request in other VPNs because (a) it is already been audited and there is nothing new to audit; (b) auditing is a costly process and auditing again for the sake of display in audit reports is a waste of time; and (c) the service request information along with the audit run information is already available in the VPN Console.
If you have a service request in multiple VPNs, look for the audit report in the VPN that comes first in the alphabetical sequence.
3.Question: What is the Show Processed Config Text button? How does it differ from the configuration file?
Answer: When performing a deployed test, MPLS VPN Solution software executes an “attribute based” audit. This means that the Auditor builds a software model of the router. To do this, the product takes all the relevant configuration commands from the router. Then the product builds the software model. MPLS VPN Solution software runs the provisioning and auditing functions using this software model as a basis.
The configuration text is the computed configuration file of the router’s software model. The software model does not model all aspects of the router configuration, such as enable passwords and clock commands, so the configuration text does not contain everything that the configuration file contains. It does contain all the relevant information such as interface commands, routing protocol commands, and their dependencies (such as access lists,
4.Question: How do I move my service request to the Functional state?
Answer: When you are scheduling an audit task (by choosing Auditing > Generate Service Request Audit Reports), you must check the check box, Use VPN routing information during audits.
