Based on your other posts it looks like you are running a Cisco 10k

Here's the command-notes to "cable wideband auto-reset" per Cisco:
------------
Use this command to enable wideband auto-reset mode on the CMTS. If wideband auto-reset mode is enabled, wideband cable modems registered on a cable interface as traditional DOCSIS modems (DOCSIS 1.x/2.0 modems) are auto-reset when the cable interface becomes wideband-capable. When a wideband cable modem auto-resets, it deregisters on the CMTS as a traditional DOCSIS cable modem and immediately attempts to re-register as a wideband cable modem.
A cable interface is considered wideband-capable when at least one fully configured and operational wideband channel has been associated with the interface’s traditional DOCSIS (narrowband) channel.

For a fully configured wideband CMTS, wideband cable modems may register as traditional DOCSIS modems for a variety of reasons, such as cable interface line card boot order or line card online insertion and removal (OIR). Rather than defer wideband cable modem registration, wideband cable modems are permitted to register as traditional DOCSIS modems.
If a wideband-capable modem registers as a traditional DOCSIS modem, it registers on a primary downstream channel that has been assigned with the downstream cable command to the modem’s fiber node if the fiber node is configured. If the modem’s fiber node is not configured, the wideband-capable modem can register on any downstream channel that is visible to it (as a traditional cable modem does). When and if a cable interface becomes wideband capable, wideband cable modems that have registered as traditional DOCSIS modems are reset for CMTS routers with wideband auto-reset mode enabled. These modems are only reset when the interface first becomes wideband-capable and are not reset again if they subsequently fail to register as wideband cable modems.

yep is a 10k
Thanks a lot
