mpls mldp-tree-number threshold-alarm

Function

The mpls mldp-tree-number threshold-alarm command sets the upper and lower alarm thresholds for the number of mLDP LSPs.

The undo mpls mldp-tree-number threshold-alarm command restores the default upper and lower alarm thresholds for the number of mLDP LSPs.

By default, the upper alarm threshold is 80%, and the lower alarm threshold is 75%.

Usage Guidelines

Usage Scenario

If the number of established mLDP LSPs reaches a specified upper limit, no more mLDP LSPs can be established due to a failure to apply for related resources. If the number of used mLDP LSP resources reaches a specified threshold, a device displays an alarm. To set the upper and lower alarm thresholds for the number of mLDP LSPs, run the mpls mldp-tree-number threshold-alarm command.

If mLDP LSP usage on a device reaches upper limit, an alarm is generated.
If mLDP LSP usage on a device falls below lower limit, a clear alarm is generated.

Precautions

If the mpls mldp-tree-number threshold-alarm command is run more than once, the latest configuration overrides the previous one.
The mpls mldp-tree-number threshold-alarm command only configures the trigger conditions for alarms and clear alarms. Although trigger conditions are met, an alarm and its clear alarm can be generated only after the snmp-agent trap enable feature-name command is run to enable the device to generate an MPLS resource insufficiency alarm and its clear alarm.

Example

# Set the upper and lower alarm thresholds for the number of mLDP LSPs to 40% and 30%, respectively.
