Hello,
i want to enable more DS RF channels into one service group and mac domain to have more capacity that basich 32 primary channels offers.
Is there any way to set up / add more RF channels and include them to same service group/ docsis mac?
I can see the QAM interface provides to configure 48 chanels, but i cant add more than 32 into service group.
I am receiving this error message:
CASA-C100G(conf-if-mac 9)# downstream 33 interface qam 0/7/32
Invalid channel id 33 as primary, channel should be 0-31.
how to add more channels to the same RP ports pls?
Thank you
BR

Maybe you need to check the amount of licensed channels?
#show system
Module 0 QAM_8x192 Running (8 ports, 64 channels/port, 128 shared channels, 2 ofdm channel/port)
Docsis channel: 128 --> In my case, 16 channels per DS port.
Casa only allows 32 primary channels, any other channels you add will need to be secondary
Not only does Casa only allow 32 primary channels, but they have to be assigned to indexes 0-31 as well when you add to your mac-domain.
so in your case
downstream 33 interface qam 0/7/32 secondary
will allow you to add the 33rd channel to the mac-domain.
Thank you, i was able to add few more channels as secondary. Added them also int service groups. But after 2 hours i still cant see any modem connected to this channel. Is that normal?
I am also monitoring channels via grafana ant there was not added any new DS frequencys automaticly...
Any idea?
This is really going to depend on a few things:
What are you monitoring to see if modems are connected? Secondary channels, will not show modems in traditional columns, they will only show up in the secondary column when you run show cable modem for example.
i.e. 200:0/0.0w is a secondary only channel, so it shows a total of 1 modem and it shows a 1 in secondary column only

200:0/0.2/0 2 0 0 0 2 0 0 node 1 - node 1 - Port A & B
200:0/0.3/0 0 0 0 0 0 0 0 node 1 - node 1 - Port A & B
200:0/0.0w 1 0 0 0 1 0 0 ofdma
Total: 6 1 1 0 5 0 1
The other thing that matters is your load-balance settings.
These load-balance settings will balance modems based on 2 criteria:
- method modem balances the modems when they register
- method utilization dynamic balances the modems from channel set to channel set based on the load, which will start balancing the channels when they hit 15% utilization.
