C H A P T E R 42 Configuring Cisco Ios Ip Slas Operations - Cisco WS-CBS3032-DEL Software Configuration Manual

Understanding Cisco IOS IP SLAs
Because Cisco IP SLAs is Layer 2 transport independent, you can configure end-to-end operations over
disparate networks to best reflect the metrics that an end user is likely to experience. IP SLAs collects a
unique subset of these performance metrics:
Delay (both round-trip and one-way)
•
• Jitter (directional)
• Packet loss (directional)
• Packet sequencing (packet ordering)
Path (per hop)
•
Connectivity (directional)
•
Server or website download time
•
Because Cisco IOS IP SLAs is SNMP-accessible, it can also be used by performance-monitoring
applications like CiscoWorks Internetwork Performance Monitor (IPM) and other third-party Cisco
partner performance management products. You can find more details about network management
products that use Cisco IOS IP SLAs at this URL:

Using IP SLAs can provide these benefits:
• Service-level agreement monitoring, measurement, and verification.
• Network performance monitoring
–
–
IP service network health assessment to verify that the existing QoS is sufficient for new IP services.
•
Edge-to-edge network availability monitoring for proactive verification and connectivity testing of
•
network resources (for example, shows the network availability of an NFS server used to store
business critical data from a remote site).
Troubleshooting of network operation by providing consistent, reliable measurement that
•
immediately identifies problems and saves troubleshooting time.
• Multiprotocol Label Switching (MPLS) performance monitoring and network verification (if the
switch supports MPLS)
