The DCC movable checks listed above are evaluated for a CM to be considered movable/non-movable via DCC. In addition,
for a bonded CM to be considered movable via DCC, the load balance type associated with its load balance group must
include bonded-dcc.
The DBC movable checks listed above are evaluated for a CM to be considered movable/non-movable via DBC. In addition,
for a bonded CM to be considered movable via DBC, the load balance type associated with its load balance group must
include bonded-ds-dbc and/or bonded-us-dbc.
Manual Modem Moves
This section provides information on how to move modems manually via DCC or DBC.
CLI Modem Move via DCC
The following CLI command is used to manually move a CM to a new upstream and/or downstream channel via the
Dynamic Channel Change (DCC) function. It can be used even if load balancing is disabled. This does not work for D1.0
modems.
configure cable modem move <mac-addr> cable-downstream <slot/dsport> cable-upstream
<slot/uport[.lchan]> method {reinit-mac | broadcast-ranging | unicast-ranging |ranging | direct}
Before a modem is manually moved via DCC, the following cross-checks are performed:
Has no Unsolicited Grant Services (UGS) service flows or any service flows that are dynamically created (e.g.
packetcable multimedia gates).
Has no dynamic multicast service flows, such as IP Video, unless the specified method is reinit-mac.
Is not under electronic surveillance, unless the specified method is reinit-mac.
Is not running on battery power.
Note: When using the manual move command to DCC a bonded modem, the reinit-mac technique will always be used,
regardless of the method identified in the command. The exception to this is in the case of a DCC of a bonded Nx1 modem
that is not changing DS channels and has no Transmit Channel Set (TCS) associated with the US channel, the command
supports the method specified on the command line and does not force the reinit-mac initialization technique.
