What is bigipNodeDown?

This OID is an alarm notification that fires when a backend server node becomes unavailable or unreachable. It indicates that a load balancer has detected a server is down and has likely stopped sending traffic to it. An operator would configure alerting on this notification to be notified immediately when a web server fails so they can investigate or failover to another server.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' F5-BIGIP-COMMON-MIB::bigipNodeDown
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.3375.2.4.0.12

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:52786->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (311928370) 36 days, 2:28:03.70
  SNMPv2-MIB::snmpTrapOID.0 = OID: F5-BIGIP-COMMON-MIB::bigipNodeDown

SNMPv3 example:

snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' F5-BIGIP-COMMON-MIB::bigipNodeDown
