IP SLA (Service Level Agreement) Commands

The IOS IP Service-Level Agreement (IP SLA) feature measures the ongoing behavior of
the network. The measurement can be as simple as using the equivalent of a ping to determine if an IP address responds, or as sophisticated as measuring the jitter (delay variation)
of VoIP packets that flow over a particular path. To use IP SLA, an engineer configures IP
SLA operations on various routers, and the routers will then send packets, receive responses, and gather data about whether a response was received, and the specific characteristics of the results, such as delay and jitter measurements.

Tracking:
#track 2 ip sla 11 state/reachability
#delay up 90 down 90 - optional
#ip route  10.0.0.0 255.255.255.0 s0/0 track 2

#ip next-hop verify-availability 10.0.0.1 25 track 2

#show track

#show ip sla configuration

#show ip sla statistics 11
Latest operation return code: OK/ No connection
