Does a target device need to be a router that supports IP SLA?
A. No. IPM supports target devices as long as they are reachable through IP. These target devices can be Web servers, PCs, printers, routers, switches, network devices, or any other device with an IP address. However, if you are measuring UDP Jitter statistics for applications such as Voice over IP or VPN monitoring, the target devices must be a Cisco router running a release of the Cisco IOS software that supports the IP SLA Responder feature Cisco IOS version 12.1(2)T or later. We recommend version 12.1 or later.
