Is it possible for Spectrum Service Performance Manager (SPM) to do HTTP tests on ports outside of the default 80? Can I state the http://abc.com:1234/test ?
Yes. You can specify a port outside of the default 80 when entering the Destination URL when configuring an HTTP test with Spectrum Service Performance Manager.
Please reference the "Service Performance Manager" section of the documentation for more information on creating SPM tests in Spectrum.
