mplsTunnelUp
Module: MPLS-TE-MIB
OID (symbolic): MPLS-TE-MIB::mplsTunnelUp
OID (numeric): 1.3.6.1.3.95.3.0.1
Node type: NOTIFICATION-TYPE
Description:
This notification is generated when a mplsTunnelOperStatus object for one of the configured tunnels is about to leave the down state and transition into some other state (but not into the notPresent state). This other state is indicated by the included value of mplsTunnelOperStatus.
What is mplsTunnelUp?
This notification is sent when an MPLS traffic engineering tunnel transitions from down to up state, indicating that the tunnel path has been established and is ready to carry traffic. The notification includes the tunnel's new operational status as part of the event data. Operations teams use this trap to detect when tunnels come back online after failures, enabling rapid notification of restoration events and updates to network status dashboards.
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-TE-MIB::mplsTunnelUp snmptrap -v2c -c public <manager> '' 1.3.6.1.3.95.3.0.1
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
