Setting up a Cisco uBr7246VXR

I have a small private RV resort we are working on. In 2006 we designed and built the TV side of the system, all underground cabling. Yes we kept the future in mind, using all 1 ghz passives, 2 way amps ect. Now that their wifi system is overloaded its time for a better alternative. To the point, we have everything ready to go but need assistance with the Cisco CMTS. I've decided on the Motorola 5000 surfboard as the only cm to be used in the system. But I have a startup config problem. Any advice would be greatly appreciated. This is our recently revised version yet to be loaded:

The CMTS sits behind a Sonicwall TZ210 which only routes between their computer room and the CMTS. We're getting a DNS error but all the lights on my test modem setup at the headend all light up. I switched 2 commands from ip name server to dns-server x.x.x.x. There will be only 200 users just a basic setup to start is all I need.

So I can tell you have been

So I can tell you have been looking at this doc :

"Configuring DHCP, ToD, TFTP services on Cisco's CMTS: All-In-One Configuration"
http://www.cisco.com/en/US/tech/tk86/tk804/technologies_configuration_ex...

You seem to have followed it pretty closely, but you look to have omitted the "dns-server x.x.x.x" from the pool pcs-c3. Without this the CPE devices wont be given a DNS server.

You can test if general networking is OK by jumping on a CPE and doing some ping by IP. If that works but you cant resolve any DNS then the fix is pretty simple.

If you dont have a DNS server of your own to point this to, set it to be the DNS server of your upstream ISP (208.76.222.222 and 208.76.222.220?), or last resort you could use the Google public DNS servers 8.8.8.8 and 8.8.4.4.

Its uBR- MC28C DOCSIS 3.0 compatible????

I need to know if uBR- MC28C card is DOCSIS 3.0 compatible.
I have a CISCO UBR-7246VXR with UBR7200-NPE-G1 card and 4 uBR- MC28C cards. Its that hardware configuration compatible with DOCSIS 3.0??
