You must have an SLA Monitor server in your network to use the SLA Monitor feature. Most of the SLA Monitor configuration occurs on the server. Configuration on the SLA Monitor agent is minimal. The SLA Monitor server initiates the SLA Monitor functions on one or more agents. The agents run specific QoS tests at the request of the server. Agents exchange packets between one another to conduct the QoS tests. SLA Monitor uses Real Time Protocol (RTP) and New Trace Route (NTR) tests to determine QoS benchmarks.
