Syntax

where:

<backup_id>	The name of the backup configuration file to be loaded.
clear	Clears the NPC buffer area before the configuration file is loaded.
<node_name>	Indicates the target node where the backup configuration file is to be loaded.
*	Specifies to load the backup configuration file on all nodes.
<source_SV_node>	The node connected to CWM where the configuration file is stored.

Function

This command loads the specified IPX configuration from CWM and stores it in a buffer area in PCC memory. The load configuration process runs in the background and may take several minutes depending on configuration file size.

When the status displays "Reserved for Firmware", a firmware image is present or being loaded. Use the getfwrev 0.0.0 command to clear a firmware image.

Once loaded, the configuration may be restored into the NPC's BRAM main memory using the runcnf command.

After using the loadcnf and runcnf commands to restore a configuration to a node(s), the PCC buffer area used for this purpose, should be cleared using the clear option of either the savecnf or loadcnf commands. This clearing of the buffer permits it to be used for future downloading processes.

Syntax

where:

<backup_id>	The name of the backup configuration file loaded from CWM. The <backup_id> must be 1-8 alphanumeric characters with the first character alphabetic.
<node_name>	Indicates the target node to rebuild with the new configuration.
*	Rebuilds all nodes using the new configuration.

Caution Restoring configurations to BPX 8600 series and IPX wide-area switch nodes should only be done by the System Administrator with Customer Service assistance. Care must be taken to run all network nodes with the same configuration or abnormal network operation will occur.

Function

This command causes the specified IPX network configuration to be restored into the BRAM memory of the specified node(s), overwriting the current configuration. Once restored, the specified node(s) are rebuilt with the restored configuration image. The rebuilding process takes a few minutes for each node.

This command is usually run after a previous configuration has been lost and the specified node needs to be reconfigured. When in doubt as to the configuration being run at other nodes in the network, load the new configuration into all nodes by specifying "*" for the node name. The new configuration must have previously been loaded into the node's buffer area with the loadcnf command.

The system may display two warning messages in response to the runcnf command. When a single node is specified:

Warning - node_name not reachable. Continue? Y/N.
 
Warning - node_name does not have the specified configuration.   Continue? Y/N.
 

When all nodes are specified:

Warning - all nodes not reachable. Continue? Y/N.
 
Warning - all nodes do not have the specified configuration.   Continue? Y/N.
 

When a single node can not be reached, responding with a yes does not affect the operation of the network. When all node(s) do not have the specified configuration or are unreachable, we recommend you do not continue until the problem is resolved.

Syntax

savecnf <backup_id> | clear <node_name> | * <dest_SV_node>

where:

<backup_id>	Name of configuration to be saved on CWM. The <backup_id> must be 1-8 alphanumeric characters with the first character alphabetic.
clear	Clears the buffer area.
<node_name>	Node name on which to save configuration.
*	Indicates all nodes.
<dest_SV_node>	Node name where CWM is connected, which will receive the specified <backup_id>.

Function

This command causes the specified BPX 8600 series and IPX node configuration to be saved on a CWM workstation. Once saved, the configuration may be restored into BRAM using the loadcnf and runcnf commands. This command should be executed periodically, as well as after making any configuration changes on a network.

When the status displayed is "Reserved for Firmware", a firmware image is present or being loaded. Use the getfwrev 0.0.0 command to clear a firmware image.

The savecnf command takes a snapshot of the IPX BRAM and sends it to a buffer in the node. Each node, in turn, transmits the snapshot of its BRAM from the buffer to the CWM workstation for storage. This process takes a few minutes per node.

After loading and restoring a network configuration, the PCC/NPC buffer area used for this purpose should be cleared using this command's clear option. Clearing the buffer permits it to be used for future downloading processes.
