I am trying to get my HWIC-Cable-D-2 going with my ISP. It syncs up fine, but remains unauthorized. The ISP validates the serial number of "the modem", but I need to know which serial number to send them.
From what I see, there are 3 possibilities:
Router Chassis serial number (not likely)
HWIC card serial number (show inventory)
CM daughter card serial number (only available through show diag)
Which is it?
And befor you ask, my ISP is a pain and I can't just cycle through it with them to find the right one.
I am using a cisco 1841 with IOS 15.1(4) with all the commands I have displayed here:
when you do a
show int cable-modem 0/0/0
I have removed the actual mac address form this device and replaced it with "x". As you can see from this out put you have both a HFC MAC and a hardware mac for the hwic-cable-d-2. Bye the way HFC is short for Hybird fiber coaxial--might want to do a little reading on this. Anyway, back on track here, the HFC MAC address or serial number is what most cable isps require to register the device on their network. This is a spare hwic-cable-d-2 that I keep in the event my 1841 v05 go's down that is why all the lines are showing down.
So call your isp back provide them with the HFC MAC address so they can register the device on their network. Here is a link to ciscos offical page for the HWIC-cable-d-2 at the end of the PDF Book you can download on this page ( link for PDF is on right side of screen) are a number of very good troubleshooting tools that might help with your sitiuatuion. Good luck and the link you need:
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
