Cisco IOS IP Service Level Agreements User Guide

Cisco IOS IP Service Level Agreements User Guide (Cisco Systems)
Cisco IOS IP Service Level Agreements (SLAs) allow users to monitor network performance between Cisco routers or from either a Cisco router to a remote IP device.
This user guide focuses on Cisco IOS IP SLAs features, and it covers usage and configuration guidelines, and explains how to retrieve data from Cisco IOS IP SLAs functionality. Configuration examples include both Command Line Interface (CLI) and Simple Network Management Protocol (SNMP). This document is a supplement to Cisco IOS Software technical documentation.
Cisco IOS IP SLAs capabilities:
• Voice-over-IP (VoIP), video, and VPN network monitoring
• SLA monitoring
• Network performance monitoring and network performance visibility
• IP service network health readiness or assessment
• Edge-to-edge network availability monitoring
• Troubleshooting of network operation
• Multiprotocol Label Switching (MPLS) network monitoring
Cisco IOS IP SLAs Benefits
• Measure end-to-end IP layer network
• Deploy new applications and services with complete confidence
• Verify and monitor quality of service (QoS) and differentiated services
• Increase end user confidence and satisfaction
• Implement SLA measurement metrics
• Notify users about network issues proactively
• Measure network performance continuously, reliably, and predictably
Cisco IOS IP SLAs Feature Overview
• Measurement capabilities
– User Datagram Protocol (UDP) response time, one-way delay, jitter, and packet loss and connectivity
– ICMP response time and connectivity
– Hop-by-hop ICMP response time and jitter
– Performance metric including DNS lookup, TCP connect, and HTTP transaction time
– Packet loss statistics
– DHCP response time measurements
– Response times from a Cisco network devices to network servers
– MOS/ICPIF Voice Quality scoring and simulation of VoIP codec's
– DLSw+ peer tunnel performance
• Proactive Notification
– Ability to define rising and falling thresholds to monitor SLAs
– Ability to generate SNMP Traps when a performance threshold is violated
– Ability to trigger another operation for more detailed analysis
• Flexible scheduling
– Measure at any given time, or continuously at any time interval
– Sequential activation for a large number of IP SLAs operations by utilizing multioperation scheduler
