 | Caution Restoring configurations to BPX/IPX nodes should ONLY be done by a System Administrator. |
This appendix contains descriptions of the following configuration save and restore commands:
This command displays the status for the configuration save/restore processes on all nodes in the network.
The display lists the various nodes, the backup ID name of the saved configuration, the time and date saved, and the StrataView Plus workstation it is saved on. See Figure A-1 for an example.
If 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.

loadcnf, runcnf, savecnf
This command is used to load a configuration image from StrataView Plus into a node.
loadcnf <backup_id | clear> <node_name|*> <source_SV_node>
where:
| backup_id | the name of the backup configuration file to be loaded. |
| clear | clears the NPC buffer area before the config. file is loaded. |
| node_name | indicates the target node where the backup config. file is to be loaded. |
| * | specifies that the backup config. file is to be loaded to all nodes. |
| source_SV_node | node connected to the SV+ where the config. file is stored. |
This command causes the specified IPX configuration to be loaded from StrataView Plus and stored 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.
If 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 "clear" option of either the savecnf or loadcnf command. This clearing of the buffer permits it to be used for future downloading processes.
Refer to the savecnf command for details on how to store a configuration onto the StrataView Plus.

dspcnf, runcnf, savecnf
This command is used restore a network configuration image at a node.
runcnf <backup_id> <node_name| *>
where:
| backup_id | the name of the backup configuration file loaded from StrataView Plus. |
| node name | indicates the target node to rebuild with the new configuration. |
| * | rebuilds all the nodes using the new configuration. |
| Caution Restoring configurations to BPX/IPX nodes should ONLY be done by the System Administrator with StrataCom ISC assistance. Care must be taken to run all network nodes with the same configuration or abnormal network operation will be experienced. |
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) will rebuild 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. If 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 nodes buffer area with the loadcnf command.
There are two warnings that the system may display 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.
If a single node is not reachable, responding with a yes does not affect the operation of the network. If node(s) do not all have the specified configuration or all are unreachable, it is not recommended that you continue until after the problem is resolved.

loadcnf, savecnf
This command is used to save a node configuration image on StrataView Plus.
savecnf <backup_id | clear> <node_name|*> <dest_SV_node>
where:
| backup_id | Name of configuration to be saved on StrataView Plus. The Backup ID must be 1-8 alphanumeric characters with the first character being alphabetic. |
| clear | may be specified to clear the buffer area. |
| node_name | Node name on which to save configuration. |
| * | may be specified to indicate all nodes. |
| dest_SV_node | Node name where StrataView Plus is connected, which will receive the specified backup_id. |
This command causes the specified BPX/IPX node configuration to be saved on StrataView Plus. Once saved, the configuration may be restored into BRAM using the loadcnf and runcnf commands. This command should be executed periodically and after making any configuration changes on a network.
If 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.
The savecnf command takes a "snapshot" of the IPX BRAM and sends this to a buffer in the node. Each node in turn transmits the snapshot of its BRAM from the buffer to the StrataView Plus workstation to be stored. 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. This clearing of the buffer permits it to be used for future downloading processes.
