Cisco's Medianet is an end-to-end architecture that is capable analyzing voice, video and data traffic and report on loss, latency and jitter thereby helping you optimize rich media applications.It enables you to monitor the flow of packets in your network and become aware of any issues that might impact the flow before it starts to significantly impact the performance of the application in question. Performance monitoring is especially important for video traffic because high quality interactive video traffic is highly sensitive to network issues. Even minor issues that may not affect other applications can have serious effects on video quality.
The Medianet performance monitoring capability(Mediatrace) gives network administrators the ability to view video performance on a specific router to isolate poor video performance. NetFlow Analyzer uses Cisco Medianet to generate reports on the voice and video performance helping network administrators to isolate specific hop of network problem and support quality of service classification or policies.
Mediatrace feature in NetflowAnalyzer uses Web Service Management Agent(WSMA) to import data from the router. To enable wsma in your router please do the following steps :
Enabling http
Router#enable Router#config terminal Router(config)#ip http server Router(config)#ip http authentication local Router(config)#end
Troubleshoot
Router#show ip http server status
Enabling Service Listener
The service listener is a type of WSMA profile that listens for incoming connections and accepts devices from allowed addresses or accepted user IDs.
Router#enable Router#config terminal Router(config)#wsma profile listener mylistener Router(config-wsma-listen)#encap soap11 Router(config-wsma-listen)#transport http path /wsma Router(config-wsma-listen)#transport http Router(config-wsma-listen)#wsse Router(config-wsma-listen)#exit Router(config)#end
Troubleshoot
Router#show wsma profile connections
Enable WSMA agents that provide access to exec
Router#enable Router#config terminal Router (config)#wsma agent exec profile mylistener Router(config)#end
TroubleShoot WSMA "%format unable to get tty"
If The Max connection for the router is reached it will throw %format unable to get tty For that you have to check the total users connected by "show users" Clear an unwanted line by using "clear line lineno"
cisco2081_routerss#show users cisco2081_routerss#show line cisco2081_routerss#clear line lineno [confirm]y [OK]

Enable Mediatrace
Before implementing a Mediatrace session, you have to enable Mediatrace on each network interface that you want to collect flow information from. The steps to enable meidatrace are given below:
SUMMARY STEPS
1. enable 2. configure terminal 3. mediatrace initiator {source-ip ip-address | source-interface interface-name} [force] [max-sessions number] 4. mediatrace responder [max-sessions number] 5. end
The Medianet Initiator must be enabled on the network interface that you will use to configure, initiate, and control the Mediatrace sessions. You can configure a Initiator using the NetFlow Analyzer web interface.
In the new pop-up window that appears
Cisco Mediatrace provides pre-packaged system-data monitoring profiles, video monitoring profile and system data profile, that contain all of the parameter settings you need to start a system-data monitoring session or video-monitoring session. The Profile configuration in NetFlow Analyzer allows you to configure a Mediatrace a monitoring profile for both system-data and video-monitoring using the web interface. In order to configure a Mediatrace Profile do the following:
The Parameters profile defines the characteristics of a Cisco Mediatrace session and help it to operate smoothly.
A flow-specifier profile defines the source IP address, destination IP address, source port, destination port, and protocol that identifies a flow. A Mediatrace session configuration requires a flow specifier to identify the flows. The session configuration in NetFlow Analyzer allows you to configure a flow profile using the web interface. In order to configure a flow specifier do the following:
The Mediatrace session allows you to link the profiles created, to a session. Only one of each type of profile can be associated with a Cisco Mediatrace session. The session configuration in NetFlow Analyzer allows you to link the profiles and sessions using the web interface. In order to configure a session do the following:
The start session configuration allows you to schedule a mediatrace session to begin when you want to start collecting the data. The session performs according to the profiles it is associated with. If the Cisco Mediatrace session is designed to collect performance monitoring metrics, it goes out to enable the Performance Monitor when the session begins. NetFlow Analyzer allows you to start a session using the using the web interface. In order to start a session do the following:
