CNA
    Converged Network
        Analyzer is an application suite available from Avaya that allows the server to determine
        the best possible network path. The CNA Agent is a software piece of the entire CNA
        application that you install on Extreme Networks devices. You use the CNA Agent software
        only if you are using the Avaya CNA solution, and the CNA Agent cannot function unless you
        also obtain the rest of the CNA application from Avaya.
