Monitor a BGP Session with SNMP

Intro

This was used to help with our requirement on monitoring BGP sessions via our NMS Software so the NOC could be alerted if critical BGP Sessions changed state.

OID

.1.3.6.1.2.1.15.3.1.2.ip.ip.ip.ip

Just replace IP with the ip of the bgp neighbor

Possible SNMP Output

1 = IDLE
2 = CONNECT
3 = ACTIVE
4 = OPENSENT
5 = OPENCONFIRM
6 = ESTABLISHED

SNMPGET Example

$ snmpget -mALL -v2c -c COMMUNTY HOST .1.3.6.1.2.1.15.3.1.2.xx.xx.xx.xx

BGP4-MIB::bgpPeerState.xx.xx.xx.x = INTEGER: established(6)

SNMP Translate

$ snmptranslate -mALL -IR -Td -On bgpPeerState .1.3.6.1.2.1.15.3.1.2
