About this MIB

Use this MIB to manage MPLS and LDP capabilities and MPLS BFD sessions.

MIB file name

rfc3812-mpls-te-std.mib

Notifications

mplsTunnelUp

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.2.1.10.166.3.0.1	A tunnel comes up.	Recovery	Warning	N/A (N/A)	ON

 

Notification triggers

This notification is generated when the operational state (indicated by the mplsTunnelOperStatus object) of a tunnel changes from down to another value (except for notPresent).

System impact

No negative impact on services.

Status control

ON

CLI: Use the snmp-agent trap enable te command.

OFF

CLI: Use the undo snmp-agent trap enable te command.

mplsTunnelDown

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.2.1.10.166.3.0.2	The operation state of a tunnel becomes down.	Error	Major	N/A (N/A)	ON

 

Notification triggers

For all types of tunnels, possible reasons for this notification include the following:

The interface went Down.

The configuration of the tunnel was deleted.

The link was faulty.

The tunnel was manually shut down.

Others

For RSVP-TE tunnels, possible reasons for this notification also include the following:

RSVP-TE LSP resources were preempted.

Transmission of an RSVP message timed out.

RSVP Hello mechanism detected a downstream node failure.

CSPF failed to calculate a path.

For Segment Routing TE tunnels, possible reasons for this notification also include the following:

IGP calculation or verification failed.

For static TE tunnels, possible reasons for this notification also include:

A static CR-LSP went Down.

A static SR-LSP went Down.

System impact

Service traffic carried on the tunnel will be interrupted.

Status control

ON

CLI: Use the snmp-agent trap enable te command.

OFF

CLI: Use the undo snmp-agent trap enable te command.

Recommended action

To resolve this issue:

1.Check the current tunnel interface configuration, IGP configuration, and the whole tunnel path.

  - If an explicit path is configured, check whether the interfaces on each hop of the explicit path are faulty.

If yes, clear link faults.

If no, execute step 2 or 3 according to the tunnel type.

  - If no explicit path is configured, check whether a path that satisfies the tunnel requirements exists. If yes, execute step 2 or 3 according to the tunnel type.

2.For an RSVP-TE tunnel, check whether the RSVP protocol, link bandwidth, and link affinity settings are correct.

  - If the settings are correct but the issue persists, go to step 4.

  - If the settings are not correct, edit the related configuration.

3.For a static MPLS TE tunnel, check whether static CRLSP or SRLSP settings are correct.

  - If the settings are correct but the issue persists, go to step 4.

  - If the settings are not correct, edit the related configuration.

4.If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.

mplsTunnelRerouted

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.2.1.10.166.3.0.3	A tunnel is rerouted.	Informational	Warning	N/A (N/A)	ON

 

Notification triggers

This notification is generated when a tunnel is rerouted because of the current path used by the tunnel is unreachable. If the mplsTunnelARHopTable is used, the tunnel entry in the mplsTunnelARHopTable might contain the new path of the tunnel for a time period after the agent sends this notification.

System impact

No negative impact on services.

Status control

ON

CLI: Use the snmp-agent trap enable te command.

OFF

CLI: Use the undo snmp-agent trap enable te command.

mplsTunnelReoptimized

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.2.1.10.166.3.0.4	A tunnel is reoptimized.	Informational	Warning	N/A (N/A)	ON

 

Notification triggers

This notification is generated when the optimal path is selected successfully for a tunnel during tunnel reoptimization. If the mplsTunnelARHopTable is used, the tunnel entry in the mplsTunnelARHopTable might contain the new path of the tunnel for a time period after the agent sends this notification.

System impact

No negative impact on services.

Status control

ON

CLI: Use the snmp-agent trap enable te command.

OFF

CLI: Use the undo snmp-agent trap enable te command.
