Configuring IP SLAs Operations
To disable the IP SLAs operation, enter the no ip sla operation-number global configuration command.
This example shows how to configure a UDP jitter IP SLAs operation:
Switch(config)#
ip sla 10
Switch(config-ip-sla)#
udp-jitter 172.29.139.134 5000
Switch(config-ip-sla-jitter)#
frequency 30
Switch(config-ip-sla-jitter)#
exit
Switch(config)#
ip sla schedule 5 start-time now life forever
Switch(config)#
end
Switch#
show ip sla configuration 10

Analyzing IP Service Levels by Using the ICMP Echo Operation
The ICMP echo operation measures end-to-end response time between a Cisco device and any devices
using IP. Response time is computed by measuring the time taken between sending an ICMP echo
request message to the destination and receiving an ICMP echo reply. Many customers use IP SLAs
ICMP-based operations, in-house ping testing, or ping-based dedicated probes for response time
measurements between the source IP SLAs device and the destination IP device. The IP SLAs ICMP
echo operation conforms to the same specifications as ICMP ping testing, and the two methods result in
the same response times.
