This command moves CMs by re-initializing the CM followed by a downstream frequency override and/or an upstream
channel override in the range response. It can be used to move all types of modems, including DOCSIS 1.0 modems.
CLI Modem Move via DCC Using MIBs
This feature provides an interface that supports the manual movement of a CM to a different upstream and/or
downstream channel via the Dynamic Channel Change (DCC) function. The CM’s original channel(s) and new channel(s)
must be on the same MAC Domain since cross-MAC Domain movement is not supported.
Note: The
configure cable modem move
command allows for this same functionality and is the preferred method.
An MSO can send a DCC command to a specific CM by setting the fields in the docsLoadbal3ChgOverGroup MIB. This Load
Balancing feature supports setting and acting on the following docsLoadBalChgOverGroup values:
docsLoadbal3ChgOverGroupMacAddress
docsLoadbal3ChgOverGroupInitTech
docsLoadbal3ChgOverGroupdownFrequency
docsLoadbal3ChgOverGroupMdlfIndex
docsLoadbal3ChgOverGroupUsChSet
docsLoadbal3ChgOverGroupCommit.
The DCC command accepts only a single upstream channel ID, therefore, the docsLoadbal3ChgOverGroupUsChSet MIB can
only be set to a single US channel ID. The range is 1-255.
DCC Init Technique: When setting docsLoadbal3ChgOverGroupInitTech in the MIB, use the following values:
