Hi,
Did some body already "play" with the DOCSIS options 24 with 22 and 25 with 23?
I try and try to fix somes priorisation and I got many problem to tweak the options and finished by having 3 definitions:
1- Voice Provosionning

No voice issue, but it mixed with my Traffic shaping service flows for Data. I think I've missing something into our BSR2000 CMTS, but I'm not sure...
I've made other test using, examples:
Restrict substain trafic at 64K for the destination IP address 10.25.2.3 (provisionning) and 10Mbps for anything else. I can't going up more than 64K for anything.
