Hi!
I´m new to DOCSIS 3.0/3.1 and I have an uBR7246VXR which should be run in docsis 3 mode ! I went through forums already and compared to other router configs but somehow no modem will go online in Docsis 3 mode . Here is my config maybe someone can help me out a bit . Btw I disabled the load balance at the moment cause the modems currently running in DOCSIS 2.0 mode start to switch between frequencies .Thanks in advance !

Hello,
If you need more help, you can contact me direct docsishotline@gmail.com.
I guess you are using mc88 linecards on the vxr?
A quick glance shows you don't have any fiber nodes.
You need to add fiber nodes, like this:
cable fiber-node 1
downstream Integrated-Cable 3/0 rf-channel 0-3
upstream Cable 3 connector 0
!
cable fiber-node 2
downstream Integrated-Cable 3/0 rf-channel 0-3
upstream Cable 3 connector 1
!
cable fiber-node 3
downstream Integrated-Cable 3/0 rf-channel 0-3
upstream Cable 3 connector 2
!
cable fiber-node 4
downstream Integrated-Cable 3/0 rf-channel 0-3
upstream Cable 3 connector 3
!
cable fiber-node 5
downstream Integrated-Cable 3/1 rf-channel 0-3
upstream Cable 3 connector 4
!
cable fiber-node 6
downstream Integrated-Cable 3/1 rf-channel 0-3
upstream Cable 3 connector 5
!
cable fiber-node 7
downstream Integrated-Cable 3/1 rf-channel 0-3
upstream Cable 3 connector 6
!
cable fiber-node 8
downstream Integrated-Cable 3/1 rf-channel 0-3
upstream Cable 3 connector 7
!
Follow that format for all of your linecards and cable interfaces, that should help.
@ OLdDocisisGuy Thank you very much for your help , I owe you some drinks ;-) It worked out !
I'm glad I could help out!
I have 2 of the 7246 boxes out there with mc88. They are really nice for our smaller hub sites!
ODG
Thanks a lot ! Got my smaller 7225 boxes running too now !
