450 CCNP SWITCH 642-813 Official Certification Guide
The recurring keyword can be used to schedule the test operation to run at
the same time each day, as long as you have defined the starting time withhh:mm:ss, too.
Using IP SLA
After you have configured an IP SLA operation, you can verify the configuration with theshow ip sla configuration [operation-number] command. As an example, the followingconfiguration commands are used to define IP SLA operation 100an ICMP echo testthat pings target 172.25.226.1 every 5 seconds.
Switch(config)# ip sla 100
Switch(config-ip-sla)# icmp-echo 172.25.226.1
Switch(config-ip-sla)# frequency 5Switch(config-ip-sla)# exit
Switch(config)# ip sla schedule 100 life forever start-time now
Example B-3 shows the output of the show ip sla configuration command.
Example B-3 Displaying the Current IP SLA Configuration

Tip: Be aware that the IP SLA operation command syntax has changed along the way. InCisco IOS releases 12.2(33) and later, the syntax is as shown in steps 2 through 4.
Prior to 12.2(33), the commands in steps 2 through 4 included additional keywords, asfollows:
Step 2. ip sla monitoroperation-number
Step 3. typetest-type
Step 4. ip sla monitor scheduleoperation-number
It isnt clear which version of the IP SLA commands are used in the SWITCH exam; just beprepared to see the syntax in either form.
