I have a side client who's recently upgraded their internet service from a single T1 to a 100mb fiber line. TW Telecom brought the fiber line into their building and run it through a Cisco 3400 which hands it off to TW Telecom's Adtran 4430. If I take my laptop and assign it the appropriate IP and subnet and plug straight into the Adtran I get close to full speeds so I can rule out the ISP (I think).
It comes out of the Adtran to a Cisco RVS4000 setup as a gateway and then feeds off to a Cisco SG200-50 and Cisco 248G switches. Anything from the RVS4000 and beyond on the customer side will only receive a quarter of the speeds I get if I plug straight to the Adtran. I talked to the tech from TW Telecom and they have confirmed the Adtran is hard coded for 1GB Full Duplex speeds so I'm going to assume the RVS4000 needs to match that. I'm not 100% sure on how to make sure the RVS4000 is set to that. In the Admin GUI for the RVS I've gone under the L2 Switch Port Settings and set them to match the Adtran but it makes no difference. Not even too sure if it's where I should be looking but since there doesn't seem to be any other section for it I figured what the hell.
At this point I'm assuming I'm getting some sort of port duplex conflict and need to figure out where to make adjustments. Any help on this would be greatly appreciated.
