MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.67 hwMplsDynamicLabelThresholdExceed

Trap Buffer Description

The dynamic label usage exceeds the threshold, which will affect the creation of BGP/LDP/RSVPTE/MPLS VPNs.(hwMplsDynamicLabelTotalCount=[DynamicLabelTotalCount], hwMplsDynamicLabelCurrentCount=[DynamicLabelCurrentCount], hwMplsDynamicLabelThresholdUpperLimit=[DynamicLabelThresholdUpperLimit], hwMplsDynamicLabelThresholdLowerLimit=[DynamicLabelThresholdLowerLimit])

Dynamic label usage reached the upper threshold. The creation of BGP, LDP, RSVP TE, or MPLS VPN will be affected.

In VS mode, this trap is supported only by the admin VS.

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 threshold.

Procedure

1. Run the display mpls lsp statistics command to view statistics about LSPs. Re-plan the services and delete unwanted LSPs that use dynamic labels. Then check whether MPLS_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.

2. Collect alarm information and configuration information, and then contact technical support personnel.

3. End.
