LDP Notification Objects and Notification Types

The jnxLdpTrapVars table, whose object identifier is {jnxLdp 1}, defines the objects used in the enterprise-specific LDP traps.

Note: The enterprise-specific LDP MIB requires jnxLdpTrapPrefix with 0 subidentifier for seamless translation of SNMPv2 notifications to SNMPv1 format.

Table 205: LDP Notification Objects

Object

Object ID

Description

jnxLdpLspFec

jnxLdpTrapVars 1

Contains the LSP forwarding equivalence class (FEC) in IpAddress format.

jnxLdpRtrid

jnxLdpTrapVars 2

Contains the router ID of the sending router in IpAddress format.

jnxLdpLspDownReason

jnxLdpTrapVars 3

Returns one of the following integer values to denote what might have caused the LSP to go down:

  • 1–Change in topology
  • 2–Withdrawal of label by the neighbor
  • 3–Unavailability of the neighbor because the neighbor is down
  • 4–Change in filter
  • 5–Unknown reason

jnxLdpSesDownReason

jnxLdpTrapVars 4

Returns one of the following integer values to denote what might have caused the session transition into non-existent state:

  • 0–Unknown reason
  • 1–Hold time expired
  • 2–Connection time expired
  • 3–All adjacencies are down
  • 4–Received bad TLV (type, length, and value encoding scheme)
  • 5–Received bad PDU (protocol data unit)
  • 6–Connection error occurred
  • 7–The connection was reset
  • 8–Received notification from peer
  • 9–Received unexpected end-of-file message
  • 10–The authentication key was changed
  • 11–Error occurred during initialization
  • 12–Graceful restart was aborted
  • 13– CLI command was issued to end the session

jnxLdpSesDownIf

jnxLdpTrapVars 5

Contains the SNMP index of the interface associated with the session-down event. If no interface is associated with the session-down event, then this object returns the SNMP index of any interface associated with one of the neighbors.

jnxLdpLspFecLen

jnxLdpTrapVars 6

Represents the length of the LSP FEC prefix in bits. The allowable range is 0 through 32 bits.

jnxLdpSesUpIf

jnxLdpTrapVars 7

Contains the interface index of one of the neighbors associated with the session.

jnxLdpInstanceName

jnxLdpTrapVars 8

Contains the name of the VPN interface.

Table 206 lists the enterprise-specific LDP notifications and the objects contained in each notification. The enterprise-specific LDP notifications use the objects listed in Table 205.

Object ID

Description

jnxLdpLspUp

jnxLdpTrapPrefix 1

Generated when an LSP comes back online. Typically, this trap is generated only when an LSP that has an active jnxLdpLspDown trap comes back online.

  • jnxLdpLspFec
  • jnxLdpRtrid
  • jnxLdpLspFecLen
  • jnxLdpInstanceName

jnxLdpLspDown

jnxLdpTrapPrefix 2

Generated when an LSP goes offline. This trap contains the following objects:

  • jnxLdpLspFec
  • jnxLdpRtrid
  • jnxLdpLspDownReason
  • jnxLdpLspFecLen
  • jnxLdpInstanceName

Note: For every jnxLdpLspDown trap generated, JUNOS software ensures that a jnxLdpLspUp trap is generated when the LSP comes back online.

jnxLdpSesUp

jnxLdpTrapPrefix 3

Generated when the jnxMplsLdpSesState object moves into the operational (5) state. This trap contains the following objects:

  • jnxMplsLdpSesState
  • jnxLdpSesUpIf

jnxLdpSesDown

jnxLdpTrapPrefix 4

Generated when the jnxMplsLdpSesState object moves out of the operational (5) state. This trap contains the following objects:

  • jnxMplsLdpSesState
  • jnxLdpSesDownReason
  • jnxLdpSesDownIf

The jnxLdpSesDownIf object contains the address of the interface associated with the last neighbor when the value of jnxLdpSesDownReason was allAdjacenciesDown (3).
