Understanding TWAMP
To remove an IP SLAs operation, enter the no ip sla operation-number global configuration command.
Understanding TWAMP
TWAMP consists of two related protocols. Use the TWAMP-Control protocol to start performance
measurement sessions. Use TWAMP-Test to send and receive performance-measurement probes. You
can deploy TWAMP in a simplified network architecture, with the control-client and the session-sender
on one device and the server and the session-reflector on another device.
The Cisco IOS software TWAMP implementation supports a basic configuration. Figure 15-3 shows a
sample deployment.
Figure 15-4 shows the four logical entities that comprise TWAMP.
Step 11
ip sla schedule operation-number [ageout seconds]
[life {forever | seconds}] [recurring] [start-time
