Configuring Conditions That Trigger LDP Resource Threshold-Reaching Alarms

Procedure

1. Run system-view

   The system view is displayed.

2. Run mpls

   The MPLS view is displayed.

3. Run one or more of the following commands:

   • Run mpls remote-adjacency-number threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

     Conditions that trigger the threshold-reaching alarm and its clear alarm for remote LDP adjacencies are configured.

   • Run mpls outsegment-number threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

     Conditions that trigger the threshold-reaching alarm and its clear alarm for outsegment entries are configured.

   • Run mpls mldp-tree-number threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

     The upper and lower alarm thresholds for the number of mLDP LSPs are set.

   • Run mpls mldp-branch-number threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

     The upper and lower alarm thresholds for the number of mLDP sub-LSPs are set.

   Configure the following parameters in the preceding command:

   • upper-limit-value: specifies the upper alarm threshold of the proportion of used LDP resources to all LDP resources supported by a device.
   • lower-limit-value: specifies the lower alarm threshold for the proportion of used LDP resources to all LDP resources supported by a device.
   • upper-limit-value must be greater than lower-limit-value.

   By default, the upper threshold for alarms is 80% and the lower threshold for clear alarms is 75%.

   

   • Each command only configures the trigger conditions for an alarm and its clear alarm. Although trigger conditions are met, the alarm and its clear alarm can be generated only after the snmp-agent trap enable feature-name mpls_lspm trap-name { hwmplsresourcethresholdexceed | hwmplsresourcethresholdexceedclear } command is run to enable the device to generate an LDP resource insufficiency alarm and its clear alarm.

   • After the snmp-agent trap enable feature-name mpls_lspm trap-name { hwmplsresourcetotalcountexceed | hwmplsresourcetotalcountexceedclear } command is run to enable the device to generate an LDP resource insufficiency alarm and its clear alarm, note the following issues:

     • If the number of used LDP resources reaches the maximum number of LDP resources supported by a device, a maximum number-reaching alarm is generated.

     • If the number of used LDP resources falls to 95% or below of the maximum number of LDP resources supported by a device, a clear alarm is generated.

4. Run commit

   The configuration is committed.
