mplsL3VpnVrfDown
Module: MPLS-L3VPN-STD-MIB
OID (symbolic): MPLS-L3VPN-STD-MIB::mplsL3VpnVrfDown
OID (numeric): 1.3.6.1.2.1.10.166.11.0.2
Node type: NOTIFICATION-TYPE
Description:
This notification is generated when: a. One interface is associated with this VRF, and the ifOperStatus of this interface changes from up(1) to down(2).
b. Multiple interfaces are associated with this VRF, and the ifOperStatus of all except one of these interfaces is equal to up(1), and the ifOperStatus of that interface changes from up(1) to down(2).
c. The last interface with ifOperStatus equal to up(1) is disassociated from a VRF.
What is mplsL3VpnVrfDown?
This OID represents an alarm notification triggered when a virtual routing domain (VRF) loses all its active network connections and becomes non-operational. It indicates network connectivity loss for that isolated routing instance. A network operations center would receive this alert to immediately investigate connectivity failure.
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> '' MPLS-L3VPN-STD-MIB::mplsL3VpnVrfDown snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.10.166.11.0.2
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]:56206->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (178210190) 20 days, 15:01:41.90 SNMPv2-MIB::snmpTrapOID.0 = OID: MPLS-L3VPN-STD-MIB::mplsL3VpnVrfDown
SNMPv3 example:
snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' MPLS-L3VPN-STD-MIB::mplsL3VpnVrfDown
