Obtaining Technical Assistance
CBOS is the common operating system for Cisco customer premises equipment (CPE). The CBOS is modeled after Cisco IOS software and features a similar command syntax and format. This operating system is bundled with the CPE products listed below and can also be downloaded from Cisco Connection Online.
The CBOS Release 2.4.2 supports the following Cisco CPE products:
 |
Note Auto-provisioning has not been tested with the 673 platform. |
The following items are new features in CBOS 2.4.2.
Three new CLI commands have been added to CBOS 2.4.2:
The set mmi command requires at least one of the following arguments:
enabled—enable auto-provisioning
disabled—disable auto-provisioning
vpi1 n vci1 n1—set mmi primary VC parameters
vpi2 n vci2 n2—set mmi secondary VC parameters
user user name—set mmi user name
context name—set the mmi context name
retry n—set the mmi retry count
timeout n—set the mmi timeout in milliseconds
poll n—set mmi default poll interval in seconds
search_timeout—set the maximum time in seconds for the CPE to transition from the searching state to the training state
training_period—set the maximum time in seconds for the CPE to transition from the training state to the trained state
line_stable_time—set the minimum time in seconds for the line to be considered stable
The following example shows the status that the show mmi command now returns:
Is enabled
primary vpi = 0, primary vci = 16
secondary vpi = 1, secondary vci = 3
current vpi = 0, current vci = 16
User Name = mmi
Context Name = mmi
Retry Count = 2
Timeout In msec = 5000
Default Poll Interval = 300
Current Poll Interval = 0
Current Search Timeout in sec = 10
Current Line Stable Time in sec = 10
Current Training Period in sec = 120
Passwords are now stored in MD5 encryption. See the "Encryption and Upgrading" section for more information.
The CBOS can detect which VPI/VCI to use for MMI communication. CBOS first attempts to use the primary channel. (The default is 0/16.) If no response is received on the primary channel, the CPE attempts to use the secondary channel. (The default is 1/3.) If no response is received after the time set for the Retry Count, an error message is returned.
Support for autoprovisioning is now set to off by default. There is an image of CBOS 2.4.2 with autoprovisioning enabled by default available on CCO. This image is v2.4.2ap. Consult your Cisco representative for details.
For information on upgrading your software from a previous version, see the Release Notes for the Cisco Broadband Operating System 2.3.5.

Caution Before you upgrade, make sure your running configuration and NVRAM configuration match. Otherwise, any running config commands that have not been saved to NVRAM will be lost. |
This section contains important information regarding password encryption.
|
Caution CBOS 2.4.2 has MD5 password encryption enabled by default. |
If you are upgrading from a previous release and you are not using a password, you will not need to use passwords. If you are upgrading but you were using passwords, CBOS 2.4.2 will encrypt those passwords and save them into NVRAM. There is no change visible to the end user.
To disable encryption, enter:
set password encrypt disableCBOS will return the following statements:
MD5 password encryption Disabled.
Since the old passwords can not be recovered,
the Enable and Exec passwords have been cleared.
To assign new passwords, use the CLI commands.
You must type "write" to persist encryption mode into memory.
You must then use the write command to make the change permanent. You can then add passwords, but they will not be encrypted.
To enable encryption, enter the following command:
set password encrypt enableCBOS will return the following statements:
MD5 password encryption Enabled.
You must type "write" to persist encryption mode into memory.
You must then use the write command to make the change permanent.
|
Caution If you forget an encrypted password, you must contact your Service Provider or TAC. |
The following issues have been resolved in CBOS 2.4.2.
This section lists open issues for CBOS 2.4.2.
|
Caution Before you upgrade to CBOS release 2.4.2 or higher, make sure your running configuration and NVRAM configuration match. Otherwise, any running config commands that have not been saved to NVRAM are lost. |
