Step 1 | enable
Example:
Router> enable
|
Enables
privileged EXEC mode.
- Enter your password if
prompted.
|
Step 2 | configure
terminal
Example:
Router# config t
|
Enters global
configuration mode.
|
Step 3 | cable submgmt
default active
Example:
Router(config)# cable submgmt default active
|
Enables the
Cisco CMTS Static CPE Override feature behind the subscriber’s cable modem.
Additional CPE devices (with additional MAC addresses) are supported behind the
subscriber’s cable modem, and they inherit the subscriber’s current SID
settings.
Note
| The
subscriber’s CPE device changes from dhcp cpe to static CPE in the CMTS host
table.
|
|
Step 4 | cable submgmt
default filter-group cm (downstream | upstream)
Example:
Router(config)# cable submgmt default filter group cm downstream
|
Enables one
or more temporary CPE devices behind a subscriber’s cable modem to operate
within the cable modem’s downstream or upstream filter group.
|
Step 5 | cable submgmt
default filter-group cpe {downstream | upstream}
Example:
Router(config)# cable submgmt default filter-group cpe upstream
|
Enables one
or more temporary CPE devices behind a subscriber’s cable modem to operate
within the subscriber’s CPE downstream or upstream filter group.
|
Step 6 | cable submgmt
default learnable
Example:
Router(config)# cable submgmt default learnable
|
Enables one
or more temporary CPE devices behind a subscriber’s cable modem to learn and
operate within the routing table defined on the Cisco CMTS.
|
Step 7 | cable submgmt
default max-cpe n
Example:
Router(config)# cable submgmt default max-cpe 1024
|
Sets the
maximum number of CPE devices to be allowed behind a subscriber’s cable modem.
- n—The number of allowable
CPE devices in addition to the subscriber’s CPE device(s), with a range from 0
to 1024 devices. Each device inherits the SID settings as defined by the
subscriber’s current SID.
|
Step 8 | interface
slot/[subslot]/port
Example:
Router(config)# interface 8/1/0
|
Enters
interface configuration mode for the specified interface. The subslot is
required syntax for the Cisco uBR10012 router, but is not used for the Cisco
uBR7246VXR or Cisco uBR7100 series routers.
|
Step 9 | (no) ip
address ip-address mask [secondary]
Example:
Router(config-if)# ip address 131.108.1.27 255.255.255.0
|
Sets a
primary or secondary IP address for a CPE device, use the ip address command in
interface configuration mode. To remove an IP address or disable IP processing,
use the no form of this command.
ip address
ip-address mask [secondary]
no ip address
ip-address mask [secondary]
- ip-address—Static IP address for the
CPE device.
- mask—Mask for the associated IP
subnet.
- secondary—(Optional) Specifies that
the configured address is a secondary IP address. If this keyword is omitted,
the configured address is the primary IP address.
|
Step 10 | Conduct
on-site CPE troubleshooting, as required.
|
For
additional troubleshooting guidelines, refer to the
Troubleshooting Tips.
|
Step 11 | Ctrl-Z
Example:
Router(config-if)# Ctrl^z
|
As required,
return to global configuration mode.
|
Step 12 | Do one of the
following:
- no cable
submgmt default
-
- clear
cable host
Example:
Router(config)# cable submgmt default
Example:
Router(config)# clear cable host
|
Disables
Static CPE override, and returns the on-site CPE device(s) and cable modem to
their original DHCP state (dynamic IP address with associated SID).
To clear the
CPE cable modem host from the Cisco router’s internal address tables, use the
clear cable host command in privileged EXEC mode.
clear cable
host {ip-address | mac-address}
-
ip-address—IP address for the device to be cleared.
-
mac-address—MAC address for the device to be cleared.
For
additional command information, refer to the clear cable command in the Cisco
Broadband Cable Command Reference Guide on Cisco.com.
|
Step 13 | exit
Example:
Router(config)# exit
|
Returns the
prompt to privileged EXEC mode.
|
Step 14 |
quit
|
Proper Telnet
reconnection to the Cisco router requires proper disconnect during the current
Telnet session.
Common
Telnet disconnect methods are as follows:
- Press
Ctrl+Break.
- Press
Ctrl+].
- Type
quit or send break.
Another
Telnet disconnect method is as follows:
Press
Ctrl+Shift 6 6 x.
For
additional Telnet break sequences, refer to the document
Standard
Break Key Sequence Combinations During Password Recovery
on Cisco.com.

Step 15 | Type disc 1
from the router command-line interface.
