Configuring IP SLA Reactions and Threshold Monitoring
• trigger—When the trigger keyword is configured, one or more other operations can be started. As a
You can specify reaction events. The react command with the connection-loss keyword is used as an example.
SUMMARY STEPS
1. configure
2. ipsla reaction operation operation-number
3. react [connection-loss | jitter-average {dest-to-source | source-to-dest} | packet-loss [dest-to-source
| source-to-dest] | rtt | timeout | verify-error]
4. action [logging | trigger]
5. commit
DETAILED STEPS
Command or Action
Step 1

Step 2
ipsla reaction operation operation-number
Example:
RP/0/RSP0/CPU0:router(config)# ipsla reaction
operation 432
Step 3 react [connection-loss | jitter-average {dest-to-source
| source-to-dest} | packet-loss [dest-to-source |

Example:
RP/0/RSP0/CPU0:router(config-ipsla-react)# react

result, you can control which operations can be started with the ipsla reaction trigger op1 op2 command.
This command indicates when op1 generates an action type trigger and operation op2 can be started.
Implementing IP Service Level Agreements
Purpose
Configures certain actions that are based on events under the
control of the IP SLA agent. The operation-number argument is
the number of the IP SLA operations for the reactions that are
configured. The range is from 1 to 2048.
Specifies a reaction if there is a connection-loss for the monitored
operation.
Specifies what action or combination of actions the operation
performs when you configure the react command or when
threshold events occur. The following action types are described:
• logging—Sends a logging message when the specified
violation type occurs for the monitored element. The IP
SLA agent generates a syslog and informs SNMP. Then,
it is up to the SNMP agent to generate a trap or not.
• trigger—Determines that the operational state of one or
more operations makes the transition from pending to active
when the violation conditions are met. The target operations
to be triggered are specified using the ipsla reaction
trigger command. A target operation continues until its
life expires, as specified by lifetime value of the target
