Arris SB8200 Provision - Incompatible SW file
I just upgraded from 250mbps to 1gbps and purchased a new modem, Arris SB8200. I was on the phone twice last night with Xfinity support and the modem is still not provisioned correctly. I am receiving the same speed as prior to upgrading. In checking the modem logs, it appears the provision is failing due to an incompatible SW file.

| 2-25-2021, 2:9:55 | Notice(6) | "SW Download INIT - Via Config file d11_m_sb8200_gigabit_c01.cm" |

Similar issue here. Repeated ""Config File Rejected due to Invalid or Unexpected TLV 11 encoding;CM-MAC=" messages.

It's a bug in the latest firmware. Doesn't seem to cause any issues, though.

Hmmm..... The original poster wrote this;
