Standard SNMP Version 2 Traps

Table 1 provides an overview of the standard SNMPv2 traps supported by the Junos OS. The traps are organized first by trap category and then by trap name and include their snmpTrapOID. The system logging severity levels are listed for those traps that have them with their corresponding system log tag. Traps that do not have corresponding system logging severity levels are marked with an en dash (–) in the table.

For more information about system log messages, see the Junos OS System Log Messages Reference. For more information about configuring system logging, see the Junos OS System Basics Configuration Guide.

The Junos OS also supports the following standard SNMP version 2 traps:

SNMP Version 2 MPLS Traps

The Junos OS supports the MPLS SNMP version 2 traps defined in RFC 3812, Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) Management Information Base.

You can disable the MPLS traps by including the no-trap option at the [edit protocol mpls log-updown] hierarchy level. For information about disabling the generation of MPLS traps, see the Junos OS MPLS Applications Configuration Guide.

The Junos OS supports the following MPLS traps:

  • mplsTunnelUp—Generated when an mplsTunnelOperStatus object for one of the configured tunnels leaves the down state and transitions into another state, other than the notPresent state.
  • mplsTunnelDown—Generated when an mplsTunnelOperStatus object for one of the configured tunnels enters the down state from a state other than the notPresent state.

    Note: When an LSP flaps, only the ingress and egress routers of that LSP generate the mplsTunnelUp and mplsTunnelDown traps. Previously, all the routers associated with an LSP—that is, the ingress, egress, and transit routers—used to generate the traps when the LSP flaps.

  • mplsTunnelRerouted—Generated when a tunnel is rerouted.
  • mplsTunnelReoptimized—Generated when a tunnel is reoptimized.

    Note: In Junos OS Release 8.3 and earlier, mplsTunnelReoptimized was generated every time the optimization timer expired; that is, when the optimization timer exceeded the value set for the optimize-timer statement at the [edit protocols mpls label-switched-path path-name] hierarchy level. However, in Release 8.4 and later, this trap is generated only when the path is reoptimized, and not when the optimization timer expires.

The Junos OS also supports the following L3VPN SNMP version 2 traps defined in RFC 4382, MPLS/BGP Layer 3 Virtual Private Network (VPN):

  • mplsL3VpnVrfUp—Generated when:
    • No interface is associated with this VRF, and the first (and only first) interface associated with it has its ifOperStatuschange to up.
    • Only one interface is associated with this VRF, and the ifOperStatus of this interface changes to up.
    • Multiple interfaces are associated with this VRF, and the ifOperStatus of all interfaces is down, and the first of those interfaces has its ifOperStatus change to up.
  • mplsL3VpnVrfDown—Generated when:
    • One interface is associated with this VRF, and the ifOperStatus of this interface changes from up to down.
    • Multiple interfaces are associated with this VRF, and the ifOperStatus of all except one of these interfaces is equal to up, and the ifOperStatus of that interface changes from up to down.
    • The last interface with ifOperStatus equal to up is disassociated from a VRF.
  • mplsL3VpnVrfRouteMidThreshExceeded—Generated when the number of routes contained by the specified VRF exceeds the value indicated by mplsL3VpnVrfMidRouteThreshold.
  • mplsL3VpnVrfNumVrfRouteMaxThreshExceeded—Generated when the number of routes contained by the specified VRF exceeds or attempts to exceed the maximum allowed value as indicated by mplsL3VpnVrfMaxRouteThreshold.
  • mplsL3VpnNumVrfSecIllglLblThrshExcd —Generated when the number of illegal label violations on a VRF as indicated by mplsL3VpnVrfSecIllegalLblVltnshas exceeded mplsL3VpnIllLblRcvThrsh.
  • mplsL3VpnNumVrfRouteMaxThreshCleared—Generated only after the number of routes contained by the specified VRF exceeds or attempts to exceed the maximum allowed value as indicated by mplsVrfMaxRouteThreshold, and then falls below this value.
