To move a
specified cable modem or a group of cable modems to another channel, or to test
Dynamic Channel Change (DCC) for load balancing on the Cisco CMTS, use the
following command in privileged EXEC mode.

Examples
The following
examples illustrate DCC verification, using the
test
cable
dcc command.
The following
example shows how to move a target cable modem, specified by MAC address, IP
address, or the primary SID value on the source interface to a target
downstream with the specified frequency using DCC intialization technique 0:
Router# test cable dcc [<mac-addr>|<ip-addr>|<cable-if-src><sid>] frequency <freq-value>
Frequency-value: <55000000-858000000> New Downstream Frequency in HZ.
The following
example shows how to move a target cable modem, specified by MAC address, IP
address, or the primary SID value on the source interface to a upstream channel
on a target downstream with the DCC-REQ TLV given in the specified HEX data.
Router# test cable dcc [<mac-addr>|<ip-addr>|<cable-if-src><sid>] TLV<Hex-data>
The following
example shows how to move all cable modems on a source interface to a target
downstream with the specified frequency using DCC intialization technique 0.
Router# test cable dcc <cable-if-src> frequency<frequency-value>
Frequency-value: <55000000-858000000> New Downstream Frequency in HZ.
The following
example shows how to force a cable modem to move to a modular-cable interface
7/0/0:2 with init-tech set to 0:
Router# test cable dcc 0023.4ed0.db25 modular-Cable 7/0/0:0 0 0 force
Router# show cable modem 0023.4ed0.db25
