Chapter 37 Configuring Cisco IOS IP SLAs Operations
Configuring IP SLAs Operations
• One-way mean opinion score (MOS)
• One-way latency
An IP SLAs threshold violation can also trigger another IP SLAs operation for further analysis. For
example, the frequency could be increased or an ICMP path echo or ICMP path jitter operation could be
initiated for troubleshooting.
Determining the type of threshold and the level to set can be complex, and depends on the type of IP
service being used in the network. For more details on using thresholds with Cisco IOS IP SLAs
operations, see the “IP SLAs—Proactive Threshold Monitoring” chapter of the Cisco IOS IP SLAs
Configuration Guide at this URL:

Configuring IP SLAs Operations
This section does not include configuration information for all available operations as the configuration
information details are included in the Cisco IOS IP SLAs Configuration Guide. It does include several
operations as examples, including configuring the responder, configuring UDP jitter operation, which
requires a responder, and configuring ICMP echo operation, which does not require a responder. For
details about configuring other operations, see he Cisco IOS IP SLAs Configuration Guide at this URL:
http://www.cisco.com/en/US/docs/ios/ipsla/configuration/guide/12_4t/sla_12_4t_book.html
This section includes this information:
• Default Configuration, page 37-6
• Configuration Guidelines, page 37-6
• Configuring the IP SLAs Responder, page 37-7
• Analyzing IP Service Levels by Using the UDP Jitter Operation, page 37-8
• Analyzing IP Service Levels by Using the ICMP Echo Operation, page 37-11
Default Configuration
No IP SLAs operations are configured.
Configuration Guidelines
For information on the IP SLAs commands, see the Cisco IOS IP SLAs Command Reference, Release
12.4T command reference at this URL:
http://www.cisco.com/en/US/docs/ios/ipsla/command/reference/sla_book.html
For detailed descriptions and configuration procedures, see the Cisco IOS IP SLAs Configuration Guide,
Release 12.4T at this URL:
http://www.cisco.com/en/US/docs/ios/ipsla/configuration/guide/12_4t/sla_12_4t_book.html
Note that not all of the IP SLAs commands or operations described in this guide are supported on the
switch. The switch supports IP service level analysis by using UDP jitter, UDP echo, HTTP, TCP
connect, ICMP echo, ICMP path echo, ICMP path jitter, FTP, DNS, and DHCP, as well as multiple
operation scheduling and proactive threshold monitoring. It does not support IP SLAs VoIP service
levels using the gatekeeper registration delay operations measurements.
