Configuring Conditions That Trigger CSPF Resource Threshold-Reaching Alarms

Procedure

1. Run the system-view command to enter the system view.
2. Run the mpls command to enter the MPLS view.
3. Run the mpls { cspf-link-number | cspf-node-number | cspf-nlsa-number | cspf-srlg-number } threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value command to set the upper and lower alarm thresholds for proportion of used CSPF resources to the maximum number of CSPF resources that device supports.

   Configure the following parameters in the preceding command:

   • upper-limit-value specifies the upper alarm threshold (percent) for the proportion of used CSPF resources to the maximum number of CSPF resources that a device supports.
   • lower-limit-value specifies the lower alarm threshold (percent) for the proportion of used CSPF resources to the maximum number of CSPF resources that a device supports.
   • 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%, which are recommended.

   

   • The mpls cspf 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 mpls_lspm trap-name { hwmplsresourcethresholdexceed | hwmplsresourcethresholdexceedclear } command is run to enable the device to generate an MPLS 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 maximum number-reaching alarms and their clear alarms, the following situations occur:

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

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