Hello everyone,
We are using ubr7246 with MC28 card. We would like to use docsis 3 cable modem, because our provider can't feed us with docsis 1. I or docsis 2.0 capable. I know we can use them easier on 1 channel like a docsis 1 cable-modem.
How can we do that ? I'm using the config file in the ubr7246 for cable-modem config. like the example below.
There is the config example we using for docsis 1 cable modem, but seem to doesnt work on docsis 3 cable modem.
cable config-file dhcp5m512u.cfg
service-class 1 max-upstream 512
service-class 1 max-downstream 5120
service-class 1 max-burst 3044
cpe max 1
timestamp
Thanks,
Wrangler
From memory only, it could be something like this :
When you use the CMTS to do all-in-one style where it provides the DHCP/TFTP/cm config file, it is DOCSIS 1.0 QoS. However DOCSIS 3.0 modems require DOCSIS 1.1 QoS.
Don't quote me on that, but I think it's correct.
If I am correct, then the solution would be to setup an external DHCP/TFTP server and host the cm config files there.
Most common solution would be a Linux server with ISC DHCPd and the open source "docsis project" config file compiler
