We have an x480 with a 10g connection to our provider. Optics are 10g multi-mode to our providers equipment. What would be methods of testing this circuit? My laptop only has a gig nic. There are no rx, tx, collisions or congestions on the port on the x480 that our provider connects to. Optic level when you do show port transceiver info look within the normal range. Complaints of slow internet browsing. Provider shows hardly any utilization for us and no errors. Pings and trace routes and dns all look good. How can you test a 10 gig Internet circuit? Does some hardware exist or are there any sites I could test that would accommodate 10gig testing? Thank you
