Chapter 69 Configuring Cisco IOS IP SLA Operations
Configuring IP SLAs Operations
• One-way packet loss
• One-way jitter
• 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 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 the Cisco IOS IP SLAs Configuration Guide:
