Issue/Introduction

This article covers the steps to filter 'Router Down' messages being sent from MPLS to SAM Domain Managers

Environment

Smarts 10.1.X

Resolution

The Smarts MPLS Manager receives transport root-cause problem events from the Smarts Availability Manager, including the following:

• Router Down
• Interface Down
• Interface Disabled
• NetworkConnection Down

To prevent the Router Down messages in MPLS alerts from being pulled into SAM from MPLS, do the following:

1. Open the SAM dxa-mpls-vpn-ics.conf configuration file for editing using sm_edit. This file is found here:
   <SAM>/smarts/conf/ics/dxa-mpls-vpn-ics.conf
   
   
2. Find and comment out the following line. This line responsible for the SAM Domain receiving Down notifications from MPLS.
   sev ICIM_UnitaryComputerSystem          Down               Availability        1
    
3. Save and close the dxa-mpls-vpn-ics.conf configuration file.

To apply these settings:

• Disable and Enable the MPLS domain (with reconfigure operation on each step of disable and enable) on the SAM -> Global Manager Administration Console 
  Note: This may clear and notify the alarms on the SAM domain.
  
  OR
  
  
• Restart the SAM domain.
