Step 1 | enable
Example:
Router> enable
|
Enables
privileged EXEC mode.
- Enter your password if
prompted.
|
Step 2 | configure
terminal
Example:
Router# configure terminal
|
Enters global
configuration mode.
|
Step 3 | l2tp-class
l2tp-class-name
Example:
Router(config)# l2tp-class class1
|
Creates an
L2TP class template. The template must be configured but the optional settings
are not mandatory.
Note
|
If all the
control channels have the same parameters then one template must be created for
the Cisco RFGW-10.
|
|
Step 4 | hello
seconds
Example:
Router(config-l2tp-class)# hello 15
|
(Optional)
Configures the interval used to exchange the “hello” keepalive packets in a
Layer 2 control channel.
Note
|
The “hello”
value on the Cisco RFGW-10 can be different from what is configured on the
M-CMTS router. We recommend that you specify 15 seconds on the Cisco RFGW-10. A
value of less than 10 seconds might subject the system to session flaps and may
trigger line card switchover, if the M-CMTS router experiences loss of network
connectivity.
|
|
Step 5 | retransmit
retries
max-retransmissions
Example:
Router(config-l2tp-class)# retransmit retries 5
|
(Optional)
Configures the retransmission retry settings of the control packets.
Note
|
We
recommend that you specify 5 on the Cisco RFGW-10.
|
|
Step 6 | retransmit
timeout [max |
min]
retransmit-timeout
Example:
Router(config-l2tp-class)# retransmit timeout max 1
|
Specifies
maximum and minimum retransmission intervals (in seconds) for resending the
control packets.
Note
|
We
recommend that you specify 1 second on the Cisco RFGW-10.
|
|
Step 7 | exit
Example:
Router(config-l2tp-class)# exit
|
Exits the
L2TP class configuration mode.
|
Step 8 | depi-class
depi-class-name
Example:
Router(config)# depi-class SPA0

DEPI class template.
|
Step 9 | exit
Example:
Router(config-depi-class)# exit
|
Exits the
DEPI class configuration mode.
|
Step 10 |
depi-tunnel
working-depi-tunnel-name
Example:
Router(config)# depi-tunnel SPA0
|
Creates a
DEPI tunnel template.
|
Step 11 | l2tp-class
l2tp-class-name
Example:
Router(config-depi-tunnel)# l2tp-class class1
|
Specifies
the L2TP control channel parameters to be inherited.
|
Step 12 | depi-class
depi-class-name
Example:
Router(config-depi-tunnel)# depi-class SPA0
|
Specifies
the DEPI control channel parameters to be inherited.
|
Step 13 |
dest-ip
dest-ip-address
Example:
Router(config-depi-tunnel)# dest-ip 192.0.2.155
|
Specifies
the destination IP address of the M-CMTS Gigabit Ethernet port.
|
Step 14 | exit
Example:
Router(config-depi-tunnel)# exit
|
Exits the
DEPI configuration mode.
|
Step 15 |
interface {qam |
qam-red}
slot/port[.channel]
Example:
Router(config)# interface qam 6/4.1
|
Specifies a
QAM interface or redundancy-configured (QAM-red) interface.
- slot—The
QAM or QAM-red slot for the line card on Cisco RF Gateway 10. If line card
redundancy is configured on the QAM, the interface is QAM-red. The valid range
is from 3 to 12.
- port—Interface number on the line card. The valid
range is from 1 to 12.
- .channel—(Optional) Specifies the channel on the
port. The valid range is from 1 to 4.
|
Step 16 |
cable
mode
{depi |
video} {local |
remote} [learn]
Example:
Router(config-subif)# cable mode depi remote learn
|
Sets the
mode of the QAM channel.
- depi—Specifies the DEPI mode of the QAM channel.
- video—Specifies the video mode of the QAM channel.
- local—Specifies that the QAM channel is manually
configured.
- remote—Specifies that the QAM channel is remotely
configured.
-
learn—(Optional) Specifies that the QAM channel is
in “learn” mode and the Cisco RFGW-10 can learn the channel configuration from
the M-CMTS router. All QAM channels on a single port must be in “learn” mode
for this configuration to work.
Note
|
When the
QAM is in “learn” mode, there is no need to configure all the QAM channel
parameters.
Step 17 to
Step 24 should not be executed as the parameters in these steps
cannot be changed when the Cisco RFGW-10 is in “learn” mode.
|
|
Step 17 |
cable downstream
stacking
stacking
Example:
Router(config)# cable downstream stacking 4
|
Configures
the stacking level. Stacking level can be 1, 2, or, 4.
- QAM
channel 1 is enabled on the specified RF port for stacking level 1.
- QAM
channels 1, and 2 are enabled on the specified RF port for stacking level 2.
- QAM
channels 1, 2, 3, and 4 are enabled on the specified RF port for stacking level
4.

Note
|
This
command is for Annex B only.
|
|
Step 22 |

depth
Example:
Router(config-subif)# cable downstream interleave-depth 5
|
Configures
the interleave depth.
Note
|
This
command is for Annex B only.
|

configure various combinations of the I/J values for Annex B, the input for
this command is the fee-code that is derived from the I/J values. The default
I/J values are 32/4.

modems are disconnected. The default modulation is set to 64 QAM on all cable
interface cards.
|
Step 24 | cable downstream
rf-power
power
Example:
Router(config-subif)# cable downstream rf-power 50
|
Configures
the RF power output level on an integrated upconverter.
-
