operation is similar to configuring threshold monitoring for a standard IP SLAs operation. For more 
information about proactive threshold monitoring for Cisco IOS IP SLAs, see the 

With the introduction of the LSP Health Monitor feature, a new operation parameter has been added that 
allows you to specify a secondary frequency. If the secondary frequency option is configured and a 
failure (such as a connection loss or timeout) is detected for a particular LSP, the frequency at which the 
failed LSP is remeasured will increase to the secondary frequency value (testing at a faster rate). When 
the configured reaction condition is met (such as n consecutive connection losses or n consecutive 
timeouts), an SNMP trap and syslog message can be sent and the measurement frequency will return to 
its original frequency value.

Multioperation scheduling support for the LSP Health Monitor feature provides the capability to easily 
schedule the automatically created IP SLAs operations (for a given LSP Health Monitor operation) to 
begin at intervals equally distributed over a specified duration of time (schedule period) and to restart at 
a specified frequency. Multioperation scheduling is particularly useful in cases where the LSP Health 
Monitor is enabled on a source PE router that has a large number of PE neighbors and, therefore, a large 
number of IP SLAs operations running at the same time.

Newly created IP SLAs operations (for newly discovered BGP next hop neighbors) are added to the same 
schedule period as the operations that are currently running. To prevent too many operations from 
starting at the same time, the multioperation scheduling feature will schedule the operations to begin at 
random intervals uniformly distributed over the schedule period.

Configuring a multioperation schedule for the LSP Health Monitor is similar to configuring a standard 
multioperation schedule for a group of individual IP SLAs operations. For more information about 
scheduling a group of standard IP SLAs operations, see the

 (optional)

Perform this task to configure the operation parameters, reaction conditions, and scheduling options for 
an LSP Health Monitor operation. The IP SLAs measurement statistics are stored on the source PE 
router.

The LSP Health Monitor must be configured on a PE router.
