LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.67 hwMplsDynamicLabelThresholdExceed

Description

LSPM/4/LABEL_THRESHOLD_EXCEED:OID [oid] The dynamic label usage exceeds the threshold. BGP, LDP, RSVP TE, or MPLS VPN creation will be affected. ( hwMplsDynamicLabelTotalCount=[INTEGER], hwMplsDynamicLabelCurrentCount=[INTEGER], hwMplsDynamicLabelThresholdUpperLimit=[INTEGER], hwMplsDynamicLabelThresholdLowerLimit=[INTEGER])

Dynamic label usage reached the upper limit, which adversely affected the creation of BGP/LDP/RSVP-TE/MPLS VPNs.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.4.1.2011.5.25.121.2.1.67	Warning	qualityOfServiceAlarm(3)

Parameters

Name	Meaning
oid	Indicates the MIB object ID of the alarm.
hwMplsDynamicLabelTotalCount	Total number of dynamic labels
hwMplsDynamicLabelCurrentCount	Number of dynamic labels used
hwMplsDynamicLabelThresholdUpperLimit	Upper limit of dynamic label usage
hwMplsDynamicLabelThresholdLowerLimit	Lower limit of dynamic label usage

Impact on the System

If dynamic label usage reaches a specific threshold, subsequent LSPs may fail to be established because all dynamic labels will be used.

Possible Causes

A great number of LSPs are established, and dynamic label usage reaches the upper limit.

Procedure

Run the display mpls lsp statistics command to view statistics about LDP LSPs, RSVP-TE CR-LSPs, and BGP LSPs. Re-plan the services and delete unwanted LSPs that use dynamic labels.
- For LDP LSPs, run the lsp-trigger command to modify a policy used by LDP to establish LSPs to reduce unwanted LSPs.
- For RSVP LSPs, run the undo interface tunnel command to delete unwanted RSVP-TE tunnels.
- For static LSPs, run the undo static-lsp ingress, undo static-lsp transit, and undo static-lsp static-lsp egress commands to delete unwanted static LSPs.
Then check whether LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.68 hwMplsDynamicLabelThresholdExceedClear is generated.
- If this clear alarm is generated, go to step 3.
- If this clear alarm is not generated, go to step 2.
Collect trap, log, and configuration information, and Collect alarm information and configuration information, and then contact technical support personnel.
End.
