We have recently upgraded our Arris C4 CMTSs from version 5 to version 7 Docsis3.0
We already have a large number of Dcosis2.0 emtas deployed and we have noticed that since the upgrade, the subscribers are not rate limited to their subscribed service according to the service flow definition in their CM config files (eg. 10M down, 20M down etc), but all emtas, irrespective of CM config, achieve download speeds in excess of 40Mbit
We have tested the same SFs in config files for Docsis3.0 emtas, and on Docsis3.0 emtas rate limiting works with no problem
Has anyone else observed a similar issue?
On the CMTS we are running version 7.03.01.41
