Configuring Cisco SAA CAC

Configuring Cisco SAA CAC

Cisco SAA is an application-aware synthetic operation agent that monitors network performance by measuring response time, network resource availability, application performance, jitter (interpacket delay variance), connect time, throughput, and packet loss. Performance can be measured between any Cisco device that supports this feature and any remote IP host (server), Cisco routing device, or mainframe host. Performance measurement statistics provided by this feature can be used for troubleshooting, problem analysis, and designing network topologies.

The SAA Responder, enabled using the rtr responder command, is a component embedded in the target Cisco routing device that allows the system to anticipate and respond to SAA request packets. The SAA Responder can listen on any user-defined port for UDP and TCP protocol messages. In client/server terminology, the SAA Responder is a concurrent multiservice server.

The global configuration mode commands to configure Cisco SAA CAC are as follows:

• call fallback active Enables a call request to fall back to alternate dial peers in case of network congestion

• mgcp rtrcac Enables MGCP SAA CAC

• rtr responder Enables the SAA Responder functionality on a Cisco device

The configuration shown in Example 7-6 enables all three types of MGCP VoIP CAC: SRC, RSVP, and SAA. Notice that CAC configuration commands are highlighted in the output. Comments are provided in the example in the lines preceding the CAC commands to help you identify the commands needed for a particular CAC type.
