Configuring Alarm Thresholds for LDP LSPs

Procedure

1. Run system-view

   The system view is displayed.

2. Run mpls

   The MPLS view is displayed.

3. Run mpls ldp-lsp-number threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

   The upper and lower thresholds of alarms for LDP LSP usage are configured.

   The parameters in this command are described as follows:

   • upper-limit-value specifies the upper threshold of alarms for LDP LSP usage. An alarm is generated when the proportion of established LDP LSPs to total supported LDP LSPs reaches the upper limit.
   • lower-limit-value specifies the lower threshold of clear alarms for LDP LSP usage. A clear alarm is generated when the proportion of established LDP LSPs to total supported LDP LSPs falls below the lower limit.
   • The value of upper-limit-value must be greater than that of lower-limit-value.
   

   • This command configures the alarm threshold for LDP LSP usage. The alarm that the number of LSPs reached the upper threshold is generated only when the snmp-agent trap enable feature-name mpls_lspm trap-name { hwmplslspthresholdexceed } command is configured, and the actual LDP LSP usage reaches the upper limit of the alarm threshold. The alarm that the number of LSPs fell below the lower threshold is generated only when the snmp-agent trap enable feature-name mpls_lspm trap-name { hwmplslspthresholdexceedclear } command is configured, and the actual LDP LSP usage falls below the lower limit of the clear alarm threshold.

   • After the snmp-agent trap enable feature-name mpls_lspm trap-name { hwmplslsptotalcountexceed | hwmplslsptotalcountexceedclear } command is run to enable LSP limit-crossing alarm and LSP limit-crossing clear alarm, an alarm is generated in the following situations:

     • If the total number of LDP LSPs reaches the upper limit, a limit-crossing alarm is generated.

     • If the total number of LDP LSPs falls below 95% of the upper limit, a limit-crossing clear alarm is generated.

4. Run commit

   The configuration is committed.
