ospfv3IfStateChange
Module: OSPFV3-MIB
OID (symbolic): OSPFV3-MIB::ospfv3IfStateChange
OID (numeric): 1.3.6.1.2.1.191.0.10
Node type: NOTIFICATION-TYPE
Description:
An ospfv3IfStateChange notification signifies that there has been a change in the state of a non-virtual OSPFv3 interface. This notification should be generated when the interface state regresses (e.g., goes from DR to Down) or progresses to a terminal state (i.e., Point-to-Point, DR Other, DR, or Backup).
What is ospfv3IfStateChange?
This notification is sent when an OSPFv3 (Open Shortest Path First version 3 for IPv6) interface changes state, particularly when regressing to a lower state or reaching a stable endpoint state like DR (Designated Router) or Backup Router. Monitoring these transitions is critical for understanding routing topology changes and network stability. Network operators receive these alerts to detect and investigate link failures, routing adjacency problems, or unexpected topology changes.
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> '' OSPFV3-MIB::ospfv3IfStateChange snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.191.0.10
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
