Re: Cisco uBR924 and Internet problems... [7:61754]
Yes, you're write. I called them to confirm the issue and I provided my MAC address so they will research and see if it's allowed according to their policy. There's one more question, if you don't mind: I am able to change the MAC address of my Ethernet interface, using the mac-address command through IOS. But the same command is not available to the cable-modem interface. I'm not sure if it is not allowed at all or if it's a limitation of my IOS version. Do you know if it's possible to manually set up a MAC address on the cable-modem interface? Thank you!!

Hi Leonardo, Basically, you're answering your own question: the provider lets you download a file that disables your service. Normally, this file specifies the Class Of Service you get from your provider, like upstream and downstream bandwidth. Now for some reason, the provider doesn't want to give you any service and therefore let you download a file which denies access. There is one thing that I don't understand, though. If you didn't buy this modem from your provider (or did you?) then the modem's MAC address is not registered with them. Therefore, why would they allow the DHCP server to give your modem an IP address? That doesn't make sense. On the other hand, if you did buy the modem from the ISP, then like I said, they just doesn't want to give you access for some reason (not paying your subscription fee springs to mind ;)) Bottom line: you have to contact them.

Re: Cisco uBR924 and Internet problems... [7:61754]
Leonardo, You shouldn't be able to change the MAC address on the Cable Interface. That's how the cable modem is associated to the customer and receives it's correct address scope for Class of Service, etc. The reason your 924 is receiving the disabled.bin config file is because your MAC address is unconfigured in the provisioning system. Unfortunately, the last I heard, none of the MSOs allow Cable Modem Routers on residential service. Maybe you'll get lucky. Peter, to answer your question, if the Cable Modem/Router remains 'unregistered' it will continue to range and seek an uplink. This takes up RF space and precious CPU cycles on several upstream elements. Using the disabled.bin allows the MSO to sync the Cable Modem/Router and thereby stop it from ranging and taking up bandwidth.
