Example IP SLA Configuration

IP SLA requires an ICMP timing probe to test the connection to a destination IP address. You can assign the default ICMP timing probe, $ipsla_default, which uses the default ICMP timing probe settings, or you can create and assign a custom ICMP timing probe.

This example:

• Creates IP SLA entry 2
• Sets the destination IP address for the ICMP requests
• Sets the ICMP timing probe to the default ICMP timing probe, $ipsla_default
• Sets the number of collections to 2
• Sets the distribution count to 4 and the interval to 20 milliseconds
• Sets the history ageout time to 18 minutes
• Sets the history buckets to 10 buckets with 22 samples in each bucket
• Sets the history collections to 2 and enables collection wrapping
• Sets the hops and paths to monitor (8 hops, 2 paths)
• Exits the IP SLA configuration mode
• Enters the IP SLA schedule mode
• Schedules IP SLA entry 2 to start test cycles 60 seconds after the command is entered. Each test cycle includes five tests that are each 60 seconds long. The interval between the tests in the test cycle is set to 60 seconds. The next test cycle will begin one second after the current test cycle ends.
