I hope everyone had a Great Christmas and New Years'

Yes, it's 48Qams because there's very few 3.1 modems. Qams 40,41,42 are high utilization wise, but the Qams are secondary. other ports are fine.

I can only think of scm phy | in 1/3/41, but it's 59 modems to go though. is there a way to see what modems are eating up the bandwidth on a secondary channel/Qam?

Find webhog per Service-Group

There is a nice command at Casa-CMTS to find the heavy users per Service-Group:

Sorted by downstream:

show cable modem docsis-mac [mac-domain-id] service-group [Service-Group-Name] downstream throughput

Sorted by upstream:

show cable modem docsis-mac [mac-domain-id] service-group [Service-Group-Name] upstream throughput

appreciate your help

what are your load balance

what are your load balance settings?

show load-balance running config

probably need to tweak them so that the downstream usage is more balanced.

What software version are you

What software version are you running? show version
and what does your downstream channel plan look like? show interface docsis-mac [num] topology
and show cable modem partial-service downstream?

I see successful balancing
a0c5.6282.7e20 6->6 1,3->2,3 26,25,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48->- direct dbc Success BAL 2022-01-17 09:35:32

but a ton of failed partial service recovery as well
acb3.1332.7882 1->1 1,2,3,4->2,3,4 21,17,18,19,20,22,23,24->- direct dbc cmRejected PSR 2022-01-17 09:35:21

but the partial service recovery is not being accepted at the modem side... Could be several reasons but lets tackle the easy ones first though.

do you have
cable mdd rcp verbose support
and
cable mdd rcp fragment support
on?

These control whether the CMTS can send the whole RCP (Receive Channel Profile) to the modem, especially with 48 downstream channels you need verbose. And the fragment allows it to send in multiple parts for when you have lots of channels.
