Cisco WAN Manager Operations

These topics describe how to manage Cisco WAN Manager (CWM) operations by saving and restoring node configuration files, and downloading software and firmware images:

• Saving and Restoring Configurations

• Downloading Software and Firmware

• Deleting Images

Saving and Restoring Configurations

You can save and restore node configuration files.

The Configuration Save and Restore (CSR) utility saves and restores configurations for the following node platforms:

CHA PTER

• Cisco MGX PXM45-based products (Cisco MGX 8880, Cisco MGX 8950, and Cisco MGX 8850

(PXM45))

• Cisco MGX PXM1E-based products (Cisco MGX 8830 and Cisco MGX 8850 (PXM1E))

• Cisco MGX PXM1-based products (Cisco MGX 8230, Cisco MGX 8250, and Cisco MGX 8850

(PXM1))

• Cisco SES PNNI Controller

• Cisco IGX 8400 series

• Cisco BPX 8600 series

• Cisco MGX 8220 products

Note Release 15 of CWM ConfigSave and Restore does not support HP OpenView.

Each network node stores configuration information in battery RAM (BRAM) or on the controller’s hard drive, which depends on the type of node. The node configuration includes service module-related and topology information for trunks, circuit lines, jobs, connections, and so forth. Periodically, you should make a backup copy of the node configuration to facilitate recovery in the event of a node failure. Backup configurations are restored to the node from Cisco WAN Manager (CWM).

Note For Cisco IGX and Cisco BPX nodes, the save and restore capability is a licensed feature. You must use

the cnfswfunc command on each node where you want to save and restore configurations.

Managing with the Configuration Save and Restore Utility

These tasks are used to manage the CSR utility:

• Launching the Configuration Save and Restore Utility

• Saving Node Configurations from CWM

• Saving Node Configurations for Cisco BPX and Cisco IGX Nodes

• Restoring Node Configurations from CWM

• Restoring Node Configurations for Cisco BPX or Cisco IGX Nodes

Launching the Configuration Save and Restore Utility

To launch the Configuration Save and Restore application, you can:

• Choose Tools > Administration > Configuration Save and Restore from any application.

• Right-click within any application and choose Administration > Configuration Save and Restore.

The Configuration Save and Restore: In-Progress window monitors the current save and restore operations (see Figure 10-1).

and stored in CWM. The maximum number of characters is less than 255. You must follow the UNIX filename limitation rule.

Note For Cisco BPX 8600 and Cisco IGX 8400 series nodes, the maximum number of characters is

eight.

Step 5 Depending upon the node type, enter a username in the User ID field.

The Save button is greyed out until a username and password are entered.

The PXM1-based switches (Cisco MGX 8230, Cisco MGX 8250, and PXM1-based Cisco MGX 8850) use TFTP to upload and download configurations. You must enter the correct username in the User ID field.

When you are managing your configuration files for any non-PXM1-based switches, you are required to enter a valid username in the User ID field. For information about the access privileges for Configuration Save and Restore, see Chapter 2, “Getting Started with Cisco WAN Manager.”

Step 6 Enter the password in the ConfigSave Password field.

Chapter 10 Cisco WAN Manager Operations

The PXM1-based switches (Cisco MGX 8230, Cisco MGX 8250, and PXM1-based Cisco MGX 8850) use TFTP to upload and download configurations. You must enter the correct password in the ConfigSave Password field.

When you are managing your configuration files for any non-PXM1-based switches, you are required to enter a valid password in the ConfigSave Password field that has sufficient privileges to be able to execute a configuration save operation. For information about the access privileges for Configuration Save and Restore, see Chapter 2, “Getting Started with Cisco WAN Manager.”

Step 7 Enter the timeout period in the Time Out field.

The timeout defines the period that CWM waits for the save operation to complete. Depending upon the node type, the default is between 900 sec and 5400 sec.

Step 8 Select a node or nodes from the Unselected node list pane.

Step 9 Use the arrow keys to move the node or nodes over to the Selected node list pane.

Step 10 If there are too many nodes of the same type to select from, enter a character string that defines a subset

of the complete list for selection in the Filter field.

Step 11 Click Save to initiate the process.

You receive a confirmation message in the Results pane, which indicates whether the save operation is initiated properly or not. After several minutes the system confirms a successful operation with the following message:

Config Save...done

Saving and Restoring Configurations

Note Depending upon the node type and network load, the save process can take 10 to 20 min to

complete.

If you attempt to initiate a configuration save operation on a node that is already saving configurations from a previous attempt, a message indicates that your request conflicts with another request.

For Cisco MGX nodes, you do not need to establish a telnet session for conflicting requests on the same node.

For Cisco BPX and Cisco IGX nodes, if you have downloaded a configuration and executed a configuration save immediately without executing the runcnf command first, you must:

• Right-click a node and choose Administration > Telnet to establish a telnet session with the node.

Or select a node from the Hierarchical Tree and choose Tools > Administration > Telnet.

• Enter the savecnf clear <nodename> <nodename> command to cancel the existing savecnf command

by executing the loadcnf clear command.

To cancel an existing save operation that originated from CWM:

• Click the In-Progress tab.

• Select the entry.

• Click Abort to cancel the save operation.

The files are saved to the usr/users/svplus/ConfigData/<backup ID>_<node name> directory.

For additional details, click the In-Progress tab to display an ongoing summary of the save operation.

Saving and Restoring Configurations

Note Cisco has various restore commands for the different switching platforms.

Saving Node Configurations for Cisco BPX and Cisco IGX Nodes

Chapter 10 Cisco WAN Manager Operations

You can save node configurations for Cisco BPX or Cisco IGX nodes.

The standard TFTP protocol backs up the Cisco BPX and Cisco IGX node configuration to a network server other than CWM. The network server is any machine that is connected to a LAN attached to the network, a TFTP server and disk, and stores configuration files. The configuration files are saved by using the TFTP method and are restored by using the proprietary method, and so forth. The files are stored in the correct directory with the correct filenames assumed by the proprietary protocol.

For more information about the TFTP Configuration Save and Restore facility and about the cnfswfunc command, refer to the Cisco WAN Switching Command Reference, Release 9.3.30.

Note The CWM ConfigSave and Restore feature must be enabled on the BPX and IGX nodes. When this

option is not enabled, you can not save or restore the configuration from the node.

Procedure

To save a node configuration for Cisco BPX or Cisco IGX nodes, complete the following procedure:

Step 1 Open a terminal window.

Step 2 When you establish a CLI session, you must:

a. Enter the username at the prompt.

b. Enter the password at the prompt.

Step 3 Enter the cnfswfunc command to enable or verify the Configuration Save/Restore function for a

Cisco BPX node or Cisco IGX node.

Step 4 For the Cisco BPX node, enter index number 1 for the Configuration Save/Restore function.

For the Cisco IGX node, enter index number 4 for the

Configuration Save/Restore function.

Step 5 Enter e to enable the Configuration Save/Restore function for both the Cisco BPX and Cisco IGX nodes.

Note While executing the cnfswfunc command, you are prompted for a password.

Name Description

backup ID Specifies the partial name to identify the configuration file to be saved. The name

must be 1-8 alphanumeric characters, and the first character must be alphabetic. Configuration names are case-sensitive.

clear Specifies an optional parameter that clears the buffer space in RAM of any old

configuration files before the new configuration snapshot is taken.

Note You must explicitly clear the buffer before it is loaded with a new file.

nodename Specifies the name of the node that needs to have the configuration saved. The

wildcard option, specified by an asterisk (*), is used in place of nodename to indicate all nodes are to have their configuration saved.

A directory with the name /usr/users/svplus/<backup_id>_Cfgdir is created under /usr/users/svplus/ConfigData/<backup_id>_Nodename directory.
