Running a Cisco UBR10k MC20x20V cards.
One mac domain works perfect and modems bond to all upstreams and you can see SNR CER and UCER on the interface. A second mac domain doesn't show SNR CER or UCER and does not report any modems on it, but when I look specifically at the interface it does. Is it a docsis 2 thing?

Not enough info
Perhaps provide a show cable modem verbose of one of these partial-mode modems
Probably also need to see your running config
