The mpls autoprimary-tunnel-number threshold-alarm command configures the conditions that trigger the threshold-reaching alarm and its clear alarm for Auto primary tunnel number. The conditions include the upper and lower alarm thresholds (percent) for the proportion of configured Auto primary tunnels to all supported ones.
The undo mpls autoprimary-tunnel-number threshold-alarm command restores the default upper and lower alarm thresholds (percent) for the proportion of configured Auto primary tunnels to all supported ones.
By default, the upper alarm threshold is 80%, and the lower alarm threshold is 75%.
| Parameter | Description | Value |
|---|---|---|
| lower-limit lower-limit-value |
Sets the lower alarm threshold for the proportion of configured Auto primary tunnels to all supported ones. |
The value is a percent integer ranging from 1 to 100. The lower limit must be less than the upper limit. The default value 75 is recommended. |
| upper-limit upper-limit-value |
Sets the upper alarm threshold for the proportion of configured Auto primary tunnels to all supported ones. |
The value is a percent integer ranging from 1 to 100. Set the value less than 95. Using the default value 80 is recommended. |
Usage Scenario
If the number of Auto primary tunnels reaches a specified upper limit, new Auto primary tunnel cannot be configured due to insufficient resources. To alert the administrator in operation and maintenance, enable a device to generate an alarm when the proportion of configured Auto primary tunnels to all supported ones reaches a specified upper alarm threshold. The following parameters can be configured in the mpls autoprimary-tunnel-number threshold-alarm command:
upper-limit-value: upper alarm threshold. If the proportion of configured Auto primary tunnels to all supported ones reaches the upper alarm threshold, an alarm can be generated.
upper-limit-value = Number of established Auto primary tunnels/Configured total number of Auto primary tunnels that can be establishedlower-limit-value: lower alarm threshold. If the proportion of configured Auto primary tunnels to all supported ones falls below the lower alarm threshold, a clear alarm can be generated.
lower-limit-value = Number of established Auto primary tunnels/Configured total number of Auto primary tunnels that can be establishedPrecautions
If the mpls autoprimary-tunnel-number threshold-alarm command is run more than once, the latest configuration overrides the previous one.
The mpls autoprimary-tunnel-number threshold-alarm 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 MPLS resource insufficiency alarm and its clear alarm.
