Generic BGP traps are not processed on Cisco switches

Products

• Spectrum

Issue/Introduction

The Generic BGP BackwardTransition traps (1.3.6.1.2.1.15.7.6.2 or 1.3.6.1.2.1.15.7 6 2) are not processed on Cisco Switches that have a CiscoBGP4_App application model associated with them in Spectrum. 

Environment

Release : DX NetOps Spectrum 20.2. 21.2.x

Component : Spectrum Core / SpectroSERVER

Cause

• The BGP4_App model was not associated with the CIsco Switch.
• The CiscoBGP4_App model was associated with the Cisco Switch and this application only processes the cbgpPeer2BackwardTransition trap, not the Generic BGP BackwardTransition traps (1.3.6.1.2.1.15.7.6.2 or 1.3.6.1.2.1.15.7 6 2).

Resolution

Configure the device to send the cbgpPeer2BackwardTransition to Spectrum. 

# cbgpPeer2BackwardTransition           cbgpPeer2LastError
1.3.6.1.4.1.9.9.187.0.8      0x00210d5a 1.3.6.1.4.1.9.9.187.1.2.5.1.17(1,2)\
                                        # cbgpPeer2State
                                        1.3.6.1.4.1.9.9.187.1.2.5.1.3(3,0)\
                                        # cbgpPeer2LastErrorTxt
                                        1.3.6.1.4.1.9.9.187.1.2.5.1.28(4,0)\
                                        # cbgpPeer2PrevState
                                        1.3.6.1.4.1.9.9.187.1.2.5.1.29(5,0)

Additional Information

• Cisco started supporting the CISCO-BGP4-MIB mib in favor of the standard BGP4-Mib to add IPv6 BGP peer session monitoring.  
• Spectrum was updated in 10.4.3 so that if the device supports the CISCO-BGP4-MIB (and responds to attribute cbgpPeer2LocalIdentifier with oid 1.3.6.1.4.1.9.9.187.1.2.5.1.9) then a CiscoBGP4_App model will be created.  
• If the device does still support the old BGP4-Mib (and responds to attribute bgpLocalAs with oid 1.3.6.1.2.1.15.2.0) Spectrum will not create the original BGP4_App model.  It will only create the CiscoBGP4_App model.
