Network Control Board Module


This chapter describes the Cisco ONS 15200 Network Control Board (NCB) module. For information about software configuration, refer to the Cisco ONS 15200 Command Line Interface Manual.

2.1 Functional Description

Figure 2-1 shows the front panel of the NCB module.


Figure 2-1   Network Control Board Front Panel


2.1.1 Module Function

The NCB module is the central processor unit with all of its peripherals.

The Subnetwork Manager (SNM) software on the NCB manges the Client Layer Interface Port (CLIP) modules on the internal bus. In addition to controlling all of the ONS 15200 system CLIP modules, the NCB module collects information about system status, alarms, parameters, and actions on the internal data bus. You can also store performance monitoring data from the CLIP on the NCB and upload the data to external media.

With certain limitations described below, you can configure one or two active NCBs as CLIP managers in a network; an NCB in a network that is not provisioned as an active manager of a CLIP can still inventory the CLIP. Both of these functions are limited to a distance of two controller area network (CAN) bus extensions and two Qeyton proprietary protocol (QPP) jumps.

Figure 2-3   Mounting an NCB Module


2.3.1 Back up Files from the Network Control Board

Complete the following steps to back up all of the NCB files to your PC:


Step 1   Open an MS-DOS command prompt window. To do so, select Start > Run. Open a command window by typing cmd (or command) in the Run dialog box.

Step 2   Create a directory to save the backup files.

    a. At the C:\> prompt, type mkdir foldername and press Enter, where foldername is the name of the directory you want to create.

    b. Go to the directory that will hold the backup files. At the C:> prompt, type cd foldername, where foldername is the destination folder. Press Enter.

Step 3   Open an FTP session to the NCB.

    a. At the C:\foldername> prompt, type ftp ipaddress, where ipaddress is the IP address of the 15200 system NCB. Press Enter.

    b. At the User prompt, type an ONS 15200 username with administrator privileges, followed by the password. If the username and password are correct you should see a message showing that the username is logged in.

Step 4   At the ftp> prompt, type dir and press Enter. You will see a list of all the files in the NCB.

Step 5   Copy all the files in the NCB to the backup directory in your PC. Start with the file that contains the snm.out NCB software file.

    a. At the ftp> prompt, type bin and press Enter.

    b. At the ftp> prompt, type get snm.out and press Enter.

Step 6   Back up the rest of the files that reside in the NCB to your PC.

    a. At the ftp> prompt type ascii and press Enter.

    b. At the ftp> prompt type get filename, where filename is one of the files that reside in the NCB, except snm.out. Press Enter.

    c. Repeat for each of the remaining files on the NCB.

Step 7   In your PC or laptop, open another command prompt window and verify that all of the files originally listed in the NCB are now in the backup directory.

Step 8   After you verify that you have copied all the NCB files to the PC backup directory, close the ftp window. To do so, at the ftp> prompt, type bye and press Enter. This will take you back to the C:\foldername> prompt.


Note    Always back up the qdbs.cfg file and the snm.out file together. Do not put files in Table 2-6 on the new NCB if used as replacement.

Table 2-6 lists the files that are not restored to the new NCB if used as a replacement.

Table 2-6   NCB Backup Files (not restored to a replacement NCB)

SNM Version Files

SNM 1.0(4)
SNM 1.0(5)

sys_inet.sys

SNM 1.1(1)
SNM 1.1(2)
SNM 1.1(3)

sys_inet.sys
network.cfg


Note    The file sys_inet.sys contains the ipaddress. Copying it onto the board will copy the old ipaddress onto the new NCB.
The file network.cfg contains info about the network, including the neid of the snm (NCB board). The new board will have a different neid than the old one; thus, a new network.cfg file needs to be created.
The file snm.out is the executable file.
The file qdbs.cfg is a configuration file used by snm.out, which is version specific, i.e., tied to a particular version of snm.out.




Note    Instead of using the old network.cfg file, create a new using the commit network command.

Complete the following steps to create a new network.cfg file from the command-line interface (CLI).


Step 1   At the login prompt (NCB:>) type configure network. Press Enter.

Step 2   At the configure network prompt (Network:>) type commit network. Press Enter.

Step 3   This command might take up to15 seconds to execute. This command creates a new network.cfg file, but depending on your configuration a number of intermediary files might also be created.

Step 4   Type exit and press Enter to get back to the login prompt.

Step 5   To remove any extra files, execute configure system from the login prompt (to get into the configure system mode), followed by defrag 0.



2.3.2 Determine the Parameters of the Existing Network Control Board

Follow the steps to determine the parameters of the NCB


Step 1   Open an MS-DOS command prompt window. To do so, select Start > Run. Open a command window by typing cmd (or command) in the Run dialog box.

Step 2   Telnet to the NCB. To do so, at the C:\> prompt, type telnet ipaddress where ipaddress is the IP address of the NCB. Press Enter. You should get a login prompt from the NCB.

Step 3   Log into the 15200 as an administrator user:

    a. At the NCB login prompt type a username with administrator privileges and press Enter.

    b. At the password prompt type the password for the administrator user and press Enter.

If the login is successful, you should see the NCB:> prompt.


Note    More than one user with the same username cannot be logged in at the same time. A user can not launch multiple sessions.

Step 4   Determine the current software and hardware version.

    a. At the NCB:> prompt type configure system and press Enter. You should now see the NCB:= prompt.

    b. At the NCB:= prompt type version and press Enter. Write down the NCB Part number, Revision number, and the SNM Version number.

Step 5   List the files that reside on the NCB. To do so, at the NCB:= prompt, type list 0 and press Enter. You will see the names of all the files that currently reside on the NCB. Write down the number of files and names.

Step 6   Determine if you need to defrag the NCB, i.e., if any of the files listed have the word deleted next to them. If none of the files listed have the word deleted next to the file name, skip this step.

    a. To remove files marked as deleted, at the NCB:= prompt, type defrag 0 and press Enter. You will see the message "Defragmentation in progress..." This command may take up to 30 seconds to complete.


Note    You must wait for this command to complete.

    b. When the process is complete, you will see the NCB:= prompt again. Type list 0 and press Enter. Verify that no file shows the word deleted next to it.

Step 7   Verify the IP configuration. To do so, at the NCB:= prompt type ipconf and press Enter. You will see the current NCB IP address, the subnet mask, and the gateway. Record this information for later use.

Step 8   Log out of the NCB. To do so, at the NCB:= prompt, type exit and press Enter.
At the NCB:> prompt, type exit and press Enter.

Table 2-8   NCB Backup Files

SNM Version Files that are not Backed Up Remarks

SNM 1.0(4)
SNM 1.0(5)

sys_inet.sys

 

SNM 1.1(1)
SNM 1.1(2)

sys_inet.sys
network.cfg

 

SNM 1.0(4)
SNM 1.1(1)
SNM 1.1(2)
SNM 1.1 (3)

snm.out
qdbs.cfg

This assumes that the version of the new NCB and the old one are identical. If this is not the case, these files must be replaced on the new NCB unless a downgrade or upgarde is desired.

SNM 1.0(5)

snm.out
qdbs.cfg

These files should be put onto the NCB. The old files should replace whatever is on the NCB, as the assumption is that a replacement is to be made later, going from SNM version 1.0(5) to SNM version 1.1(1) or SNM version 1.1(2).

SNM version 1.1(1) or SNM version 1.1(2) require support from two different upgrade files, both stored in CCO.

Table 2-6 lists the files that are not restored to the replacement NCB.


Note    The file sys_inet.sys contains the ipaddress. Copying it onto the board will copy the old ipaddress onto the new NCB.
The file network.cfg contains info about the network, and the neid of the snm (NCB board). The new board will have a different neid than the old one; thus, a new network.cfg file will have to be created.
The file snm.out is the executable file.
The file qdbs.cfg is a configuration file used by snm.out, which is version specific.


Note    For the network.cfg file create a new one by 'commit network' instead.

Complete the following steps to create a new network.cfg file from CLI (Command Line Interface)

Step 10   Verify that the new NCB shows the same files as the original NCB. To do so, at the ftp> prompt, type dir and press Enter. Verify that you count the same number of files as were in the original NCB.

Step 11   Close the ftp window. At the ftp> prompt, type bye.

Step 12   Reboot the NCB for the downloaded configuration to take effect.

    a. Telnet to the NCB using the administrator or operator username and password you created earlier. (See the "Create a User and Set the IP Address" procedure.)

    b. At the NCB:> prompt, type configure system and press Enter.

    c. At the NCB:= prompt, type reboot and press Enter.


Note    The NCB reboot takes approximately 1 minute.

    d. Telnet to the new NCB with an administrator or operator username that existed previously in the original NCB.


Note    The user name you created in the "Create a User and Set the IP Address" procedure is no longer valid after the reboot, because only users defined in users.cfg will be valid. After reboot the users.cfg that is copied on the NCB contains all the user settings from the previous NCB.

Step 13   Check the new NCB software version.

    a. At the NCB:> prompt, type configure system and press Enter.

    b. At the NCB:= prompt, type version and press Enter. Verify that the software version is the same as in the original NCB. In case it is not, the old snm.out and qdbs.cfg should be downloaded onto the NCB, as wanted
