CM8200 bonding issues on BSR 64000

CMTS: Motorola BSR 64000
Firmware: 8.1.0.1
Supervisor cards: SRM10G
Downstream cards: TXPlus
Upstream cards: RX48
Bonding groups: 32x4

We are seeing some CM8200 modems getting stuck in dhcp(ack) when registering. We see the following in the logs:

RCP Ignored: BondingCapable Modem xxxx.xxxx.xxxx can't register as bonded

If I reset the modem and clear out offline modems it will register fine and bond all channels on the upstream and downstream. We have not seen these issues on our newer CMTS (Casa C100G). I am wondering if I am missing a setting somewhere on the BSR. Has anyone had any experience with this log message on the BSR 64000?

Hi Bob
Can you post your cable interface config?

try adding

seems to be missing mdrc enable and cable t4-multiplier 4.
if that doesn't do the trick, I would try different modem firmware

Thanks

Will give these a try. Thanks for the tips.
