yes, because otherwise the contention (it's a shared access media, after all) and RF channel bonding/allocation wouldn't work. Configuration depends on what the exact CMTS configuration is on your last mile coax segment.

however it's also possible to have the cable MSO push an update to cablemodems which locks out a read-only diagnostics/info page that would otherwise be available.

Even if you own your modem, the DOCSIS specs require that it be
completely controlled by the MSO, right?
