To perform an RCA audit of a service or multiple services

Steps
 
1 

Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens.

2 

Choose a service or services that you want to audit and click RCA Audit. The Select RCA Policy to run the audit form opens with a list of configured policies.

Note: In addition to the standard audit checks, for BGP VPLS multi-homing sites, the audit also verifies:

Perform the following:

  • if no valid Route Targets are configured under a VPLS site that has BGP multi-homing sites configured under it.

  • if there are no matching RTs for peered multi-homing sites

  • if there are multiple RTs configured under a VPLS site that has BGP multi-homing sites configured under it. Multiple RTs will make the BGP multi-homing sites appear under multiple topologies (or multiple services, since the RT defines the service)

  • if multi-homing sites have the same multi-homing ID but different RTs (different RTs mean the sites are in different topologies or services)

  • if a multi-homing site does not have other sites as members (sharing the same multi-homing ID to comprise a group)

In addition to the standard audit checks, for SPB- enabled B-VPLS sites, the audit also verifies that:

  • all user B-VPLS SAPs or spoke SDP bindings are fate-shared with a control B-VPLS

  • control and user B-VPLS instances in the same service on different sites have the same FID

  • FID-to-ECT mapping is consistent on all of the sites for the active SPB B-VPLS services

  • control B-VPLS SPB level Unicast Forwarding Tree Topology parameter is consistent on all of the sites in the same service

Choose an RCA audit policy and click OK. The Select RCA Policy form closes and a dialog box appears with the audit information.

4 

Click OK.

If you selected multiple services to audit, perform the following. Otherwise, go to Step 6 .

  1. Scroll to the RCA Audit Problem column and set the filter to = true.

  2. Click Search. A list of services with problems appears.

  3. Select a service and click Properties. The Service (Edit) form appears with the General tab displayed.

6 

Click on the RCA Result tab. The RCA audit information is displayed on the Related Problem tab.

Note: The RCA Result tab appears only if the RCA audit detects one or more problems.

7 

If required, expand the object in the problems tree to view the problems, the associated severity, and the cause.

8 

Double-click on a problem icon to view information about the problem. The Problem (Edit) form opens with the General tab displayed.

9 

Configure the Disable Fix Window parameter, if applicable.

10 

Click on the Related Problem tab to view related problems.

Note: The NFM-P does not provide a solution for physical link configuration errors.

11 

Click on the Caused By Objects tab to view a list of objects that are causing the problem.

12 

Choose an entry from the list and click Properties. The properties form for the object opens.

14 

Configure the parameters, as required.

15 

Save the configuration and close the forms.
