Products

• VMware Smart Assurance

Issue/Introduction

This article tackles the use-case where BGPSessionGroup notificaitons are not updated with ElementName and ElementClassName on the Presentation SAM domain.

Environment

Smarts 10.1.X / 2.X

Cause

This issue occurs because the dxa-sam.conf file responsible for topology exchange between the SAM ⇔ SAM domains is not enabled to transfer the topology information with respect to BGPSessionGroup class. 

Resolution

To allow the topology exchange for BGPSessionGroup between the SAM ⇔ SAM domain managers, perform the following:

1. Determine the dxa-configuraiton file to edit by running the below from Presentation SAM and looking at the parameter: confFile:

<Base_SAM_Dir>/smarts/bin/dmctl -s <Presentation SAM Domain> get GA_DaemonDriver :: <Insert the SAM_NL-Driver-HyperNotif Name Here> :: variables 

2. Edit the file and add the following contents under the section:

<Base_SAM_Dir>/smarts/bin/sm_edit <configuration file location obtained from the above command>

and locate the following section on the file:
##############################################
#        BGP - SOLUTION SPECIFIC CLASSES     #
##############################################

3. Entries to be added to this section are:

class   BGPSessionGroup
attr    DisplayName
rel     ConsistsOf

4. Save and Close the file. 

5. Make a change to Smoothing Interval.
Example: from 65 second to 64 second for the domain type you are changing. 

6. Run reconfigure for the change to take effect. 
Note: Change also takes effect when SAM domain is restarted.
