To verify that the DBGs are created:
Check the modem’s primary wideband interface by using the show cable modem wideband channel command:
Router# show cable modem 4800.33ee.ebee wideband channel
MAC Address IP Address I/F MAC DSxUS Primary
State WB

Router# scm 4800.33ee.ebee ver
Check the modem’s downstream tuner capability by using the show cable modem verbose | in DS Tuner command.
Router# show cable modem 4800.33ee.ebee verbose | in DS Tuner
DS Tuner Capability : 32
Check the related RCC by using the show cable mac-domain rcc command:Router# show cable mac-domain c3/0/1 rcc

Check the dynamically created bonding groups, use the show cable dynamic-bonding-group summary command as shown in the example below:

Table 3. Dynamic Bonding Group States
|
|
CREATE_WAITING_SUP
|
Line card sends request to create DBG and waits for SUP to create the bonding group.
|
HOLD
|
DBG is created from SUP, or bonding group reverts from reclaim to ready for use.
|
OPERATIONAL
|
If modem is used on the bonding group after the HOLD state times out, the DBG state changes to OPERATIONAL.
|
RECLAIM_HOLD
|
Ready for reclaim.
If no modem is used on the bonding group or match the reclaim in two minutes, the bonding group is reclaimed. The DBG state
changes to RECLAIM_HOLD.
|
RECLAIM_MODEM_MOVING
|
Ready for reclaim.
The modem is moved out of the bonding group.
|
RECLAIM_WAITING_SUP
|
Line card sends DBG reclaim request and waits for SUP to reclaim the BG.
|
To show the detailed channel list information of dynamic bonding group, use the show derived-config interface wideband command.
Router# show derived-config interface wideband-Cable 3/0/1:1

Check the usage of bonding group resource by using the show cable dynamic-bonding-group quota summary | slot | controller command.
Router# show cable dynamic-bonding-group quota controller 3/0/1
slot/subslot/ctrlr: 3/0/1
Total BG number: 128
Used BG number (static/dynamic): 6(1/5) Available BG number: 122
Available BG list port: 0, 6-29, 31-127
Note
|
128 BGs can be configured on one controller, but only 896 BGs are supported per CLC. All controllers share the 896 BG resources.

Check the reclaimed bonding group by using the show cable dynamic-bonding-group reclaim-history summary command:
