TE-MIB

About this MIB

Use this MIB to manage TE tunnel interface and explicit path settings.

MIB file name

rfc3970-te.mib

Notifications

teTunnelUp

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.2.1.122.0.1	TE tunnel up	Recovery	Warning	N/A	ON

 

Notification triggers

This notification is generated when the tunnel specified by teTunnelName transitions to the up state.

System impact

No negative impact on the system.

Status control

ON

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

OFF

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

Objects

OID (object name)	Description	Index nodes	Type	Value range
1.3.6.1.2.1.122.1.2.1.2 (teTunnelName)	TE tunnel name	teTunnelIndex	SnmpAdminString	OCTET STRING (SIZE (1..32))
1.3.6.1.2.1.122.1.3.1.2 (tePathName)	Name of the TE tunnel's path	teTunnelIndex	SnmpAdminString	OCTET STRING (SIZE (0..32))

 

Recommended action

No action is required.

teTunnelDown

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.2.1.122.0.2	TE tunnel down	Error	Major	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.

Objects

OID (object name)	Description	Index nodes	Type	Value range
1.3.6.1.2.1.122.1.2.1.2 (teTunnelName)	TE tunnel name	teTunnelIndex	SnmpAdminString	OCTET STRING (SIZE (1..32))
1.3.6.1.2.1.122.1.3.1.2 (tePathName)	Name of the TE tunnel's path	teTunnelIndex	SnmpAdminString	OCTET STRING (SIZE (0..32))

 

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 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.     Collect alarm information and configuration data, and then contact Technical Support.

teTunnelChanged

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.2.1.122.0.3	TE tunnel path change	Informational	Warning	N/A	ON

 

Notification triggers

This notification is generated when the active path for the tunnel specified by teTunnelName changes or a new path becomes active. The value of tePathName is the new active path.

System impact

No negative impact on the system.

Status control

ON

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

OFF

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