Hello!
Has anyone worked before with those features (DBWS and ACFE)??
I am new at this forum and I am trying to set up a Docsis 3.0/1.1 environment taking advantage of those features. Specifically what I am trying to do is to configure in a single service group all the DS channels as primary and as bonded channels as well, and share the bandwidth among them as fairly and load balanced as possible. This will allow me to get the legacy modems online as well as the 3.0 modems. Does this makes sense to you guys?
I have read about DBWS and I guess that something like this will allow me to achieve what I want:
*This configuration example is based on a 20x20 line card for a single service group:
//Definition of primary channels (for legacy modems):
interface Integrated-Cable5/0/0:0
cable bundle 1
cable rf-bandwidth-percent 1 remaining ratio 100
!
interface Integrated-Cable5/0/0:1
cable bundle 1
cable rf-bandwidth-percent 1 remaining ratio 100
!
interface Integrated-Cable5/0/0:2
cable bundle 1
cable rf-bandwidth-percent 1 remaining ratio 100
!
interface Integrated-Cable5/0/0:3
cable bundle 1
cable rf-bandwidth-percent 1 remaining ratio 100
//Definition of wideband channel (for docsis 3.0 modems):
interface Wideband-Cable5/0/0:0
cable bundle 1
cable rf-channel 0 bandwidth-percent 1 remaining ratio 100
cable rf-channel 1 bandwidth-percent 1 remaining ratio 100
cable rf-channel 2 bandwidth-percent 1 remaining ratio 100
cable rf-channel 3 bandwidth-percent 1 remaining ratio 100
But does any body know if this will share "fairly" the available bandwidth between primary and bonded channels?? or it is mandatory to enable ACFE?, if so could you help me a little bit setting up ACFE?.
In addition, could somebody help me with the best practices for DBWS and ACFE??
Thank you in advance for your help!
The way I do it which results in a pretty good distribution is:
interface Integrated-Cable5/0/0:0
cable bundle 1
cable rf-bandwidth-percent 20 remaining ratio 100
!
interface Integrated-Cable5/0/0:1
cable bundle 1
cable rf-bandwidth-percent 20 remaining ratio 100
!
interface Integrated-Cable5/0/0:2
cable bundle 1
cable rf-bandwidth-percent 20 remaining ratio 100
!
interface Integrated-Cable5/0/0:3
cable bundle 1
cable rf-bandwidth-percent 20 remaining ratio 100
interface Wideband-Cable5/0/0:0
cable bundle 1
cable rf-channel 0 bandwidth-percent 20 remaining ratio 100
cable rf-channel 1 bandwidth-percent 20 remaining ratio 100
cable rf-channel 2 bandwidth-percent 20 remaining ratio 100
cable rf-channel 3 bandwidth-percent 20 remaining ratio 100
What this does is reserves 20% of each downstream for docsis 1.1 modems and 20 % of each downstream for docsis 3.0 modems and then shares the remaining 60%. I found it was better to allocate a little bandwidth to each type than to leave it all open for sharing, because in that case the docsis 3.0 modems were getting the lions share of the bandwidth. You can adjust the first number to balance out the usage if you need to.
Thank you for your advice!!... What about the ACFE feature? has someone worked or configured it before???
