Configuring IP SLA Reactions and Threshold Monitoring
If you want IP SLA to set some threshold and inform you of a threshold violation, the ipsla reaction operation
command and the ipsla reaction trigger command are required. Perform the following procedures to configure
IP SLA reactions and threshold monitoring:
Configuring Monitored Elements for IP SLA Reactions
IP SLA reactions are configured to be triggered when a monitored value exceeds or falls below a specified
level or a monitored event (for example, timeout or connection-loss) occurs. These monitored values and
events are called monitored elements. You can configure the conditions for a reaction to occur in a particular
operation.
The types of monitored elements that are available are presented in the following sections:
Configuring Triggers for Connection-Loss Violations
You can configure a reaction if there is a connection-loss for the monitored operation.

Step 1
Configures certain actions that are based on events under
the control of the IP SLA agent. The operation-number

Step 2
argument is the number of the IP SLA operations for the
reactions that are configured. The range is from 1 to 2048.
Specifies an element to be monitored for a reaction.react [connection-loss]
Step 3
Example:
RP/0/RSP0/CPU0:router(config-ipsla-react)# react
Use the connection-loss keyword to specify a reaction that
occurs if there is a connection-loss for the monitored
operation.
