Incorrect BGPSession Down or Disconnected alarms seen for Network Protocol Manager

Products

• VMware Smart Assurance

Issue/Introduction

Symptoms:

• Smarts Network Protocol Manager (NPM) generating incorrect notifications
• Incorrect BGPSession Down or Disconnected notifications seen for Smarts Network Protocol Manager
  
  
  

Environment

SMARTS NPM 10.1.x

Cause

BGPSession status is generated by SNMP polling the BGP4-MIB, specifically bgpPeerState:

bgpPeerState OID: .1.3.6.1.2.1.15.3.1.2

Resolution

If you believe that the BGPSession is actually established, even though Smarts is reporting the BGPSession as Down/Disconnected, you can check the OID of the bgpPeerState as follows:

• Browse to the NPM installation directory: <SMARTS>/NPM/smarts/bin
• Enter the following command: ./sm_snmp -c <community> -d <device-ip> walk .1.3.6.1.2.1.15.3.1.2
  
  Values:
  1 : idle
  2 : connect
  3 : active
  4 : opensent
  5 : openconfirm
  6 : established
  
  If the value returned is 6 (established), then the BGPSession is established and it may be necessary to open a case with Broadcom Support to investigate further why Smarts NPM is reporting the BGPSession as Down or Disconnected.
