Standard SNMP Version 2 Traps

Table 19 provides an overview of the standard SNMPv2 traps supported by JUNOS Software. 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 System Log Messages Reference. For more information about configuring system logging, see the JUNOS System Basics Configuration Guide.

JUNOS Software supports the following standard SNMP version 2 traps:

SNMP Version 2 Standard Traps

JUNOS Software supports the standard SNMP version traps, which are taken from RFC 1907, Management Information Base for Version 2 of the Simple Network Management Protocol (SNMPv2), and RFC 2863, The Interfaces Group MIB:

coldStartNOTIFICATION-TYPE
STATUScurrent
DESCRIPTION
"A coldStart trap signifies that the SNMPv2 entity, acting in an agent role, is
reinitializing itself and that its configuration may have been altered."
::= { snmpTraps 1 }
warmStartNOTIFICATION-TYPE
STATUScurrent
DESCRIPTION
"A warmStart trap signifies that the SNMPv2 entity, acting in an agent role, is
reinitializing itself such that its configuration is unaltered."
::= { snmpTraps 2 }
linkDownNOTIFICATION-TYPE
OBJECTS {
ifIndex
ifAdminStatus
ifOperStatus
ifName
}
STATUScurrent
DESCRIPTION
"A linkDown trap signifies that the SNMP entity, acting in an agent role, has
detected that the ifOperStatus object for one of its communication links is about
to enter the down state from some other state (but not from the notPresent
state). This other state is indicated by the included value of ifOperStatus."
::= { snmpTraps 3 }
linkUpNOTIFICATION-TYPE
OBJECTS {
ifIndex
ifAdminStatus
ifOperStatus
ifName
}
STATUScurrent
DESCRIPTION
"A linkUp trap signifies that the SNMP entity, acting in an agent role, has
detected that the ifOperStatus object for one of its communication links left the
down state and transitioned into some other state (but not into the notPresent
state). This other state is indicated by the included value of ifOperStatus."
::= { snmpTraps 4 }
authenticationFailureNOTIFICATION-TYPE
STATUScurrent
DESCRIPTION
"An authenticationFailure trap signifies that the SNMPv2 entity, acting in an
agent role, has received a protocol message that is not properly authenticated.
While all implementations of the SNMPv2 must be capable of generating
this trap, the snmpEnableAuthenTraps object indicates whether this trap will be
generated."
::= { snmpTraps 5 }
}
}
}
}
}

SNMP Version 2 MPLS Traps

JUNOS Software 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 on disabling the generation of MPLS traps, see the JUNOS MPLS Applications Configuration Guide.

JUNOS Software supports the following MPLS traps:

SNMP Version 2 OSPF Traps MIB

ospfIfIpAddress,
ospfAddressLessIf,
}
STATUS current
DESCRIPTION
"An ospfIfStateChange trap signifies that there has been a change in the state of a
non-virtual OSPF interface. This trap 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)."
::= { ospfTraps 16 }
ospfVirtIfStateChange NOTIFICATION-TYPE
OBJECTS {
ospfRouterId, -- The originator of the trap
ospfVirtIfAreaId,
ospfVirtIfNeighbor,

STATUScurrent
DESCRIPTION
"An ospfIfStateChange trap signifies that there has been a change in the state of
an OSPF virtual interface. This trap should be generated when the interface state
regresses (e.g., goes from Point-to-Point to Down) or progresses to a terminal
state (i.e., Point)."

DESCRIPTION
"An ospfNbrStateChange trap signifies that there has been a change in the state
of a non-virtual OSPF neighbor. This trap should be generated when the neighbor
state regresses (e.g., goes from Attempt or Full to 1-Way or Down) or progresses to a terminal state (e.g., 2-Way or Full). When a neighbor transitions from or to
Full on non-broadcast multi-access and broadcast networks, the trap should be
generated by the designated router. A designated router transitioning to Down
will be noted by ospfIfStateChange."
