Re: 6 modems listed, how do I fix this? said by plencnerb:On the bottom of each STB is a sticker that says "DOCSIS MAC" and the corresponding MAC. However, what is on the boxes and what is posted to the web page don't match.

The MAC mismatch wont be a big deal. The boxes that comcast uses (minus DTA's) have the ability to actually act like a Modem. That is use and upstream and downstream channel in a constantly connected state. This is opposed to a box monitoring an OOB channel and then only sending requests as needed. Ordering PPV, starting an ON demand stream, etc. The DOCSIS Mac you see listed would be the MAC the system would use to speak to your box. If you look in the diag page ( turn off box, press select) you should see something similiar to DOCSIS status. It should all be N/A or so.
There used to be some systems (Charter ? Moxi boxes?) that would actually let you use the box as the modem for internet access.
Your EMTA has multiple MAC address of those 1 is typically the CDV side and 1 is internet. The box kinda works the same way. It has different MAC addys depending on how it is being accessed. The one your seeing on the website is VOD access.
I think, could be wrong, but the DOCSIS Mac may be used more in areas using the Tru-Two way system. I've never worked with that system.
I wouldnt worry about the MAC's not matching. | |

I figured as much, as all three STB's have an RJ45 plug on the back of them. I figured it was either for that, or for some future use to somehow tie the STB into the internet side of things. Never did try to plug it in to see what would actually happen.

I did see that on my modem's status page, as well as listed on a sticker on the back. The status page lists 3 (LAN, CABLE, MTA) while the sticker actually lists 4 (EMAC, CMAC, MAT-MAC, USB-MAC)
Is that the reason why the modem actually shows up 3 times on Comcast's site? If that is why, then that answers my question, and I can understand why it would do that, as it does have a different MAC for each function the modem performs.
However, that still leaves one question unanswered. Why am I'm seeing 3 different Serial numbers for my eMTA modem? All three on Comcast's site match each other. However, if you look on the actual sticker on the back of the modem, there is a different number listed. Then, if you look on my modem's status page, you get a third number. I would think those should all match!
