LDP Notification Objects and Notification Types

[Contents] [Prev] [Next] [Index] [Report an Error]

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 207: 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 nonexistent 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 208 lists the enterprise-specific LDP notifications and the objects contained in each notification. The enterprise-specific LDP notifications use the objects listed in Table 207.

Table 208: LDP Notification Types

Object	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).
