> Cisco IOS IP SLAs allows you to analyze IP service levels for IP applications and services, to increase productivity, to lower operational costs, and to reduce occurances of network congestion or outages. IP SLAs uses active traffic monitoringthe generation of traffic in a continuous, reliable, and predictable manner with proactive notification capabilitiesfor measuring network performance. IP SLAs can be used for network troubleshooting, network assessment, and health monitoring.
> The ability to schedule hundreds of operations at once allows service providers with large networks to monitor service levels for mulitple environments.
> In addition to allowing you to schedule multiple IP SLAs operations with a single command, IP SLAs can be used to schedule operations to run at equal intervals, automatically distributing the operations over a specified time frame. This distribution helps to minimize the CPU utilization, thereby enhancing the scalability of the IP SLAs monitoring solution.
