Load Balancing Technique in CASA 3000

Although I have set configuration in CASA,we are seeing that some downstream are congested and some are free.Can any one help me out to resolve the issue.Currently I am using single mac-domain(2) for the cmts
I have following configuration in my CMTS.

your downstream interleaver should be down around 32, can email you a better config.
what's your email address?

Hello Carl

I'm putting together CASA 3000 for small ISP in SI. Could you please e-mail me your better config? My e-mail is peter@digitalno.net
Thank you for your help.

I'm wondering if that 'no enable' is causing an issue since it appears to be applied to the default settings; might need to test/check. "Show load-balance dynamic" should show you the load balance log of modems moving. Make sure you see activity there.

Hi

"dynamic minimum 10" is too low in my opinion.
Why lb cable modems, when utilization is around 10%? Set minimum to 50-70%.
