IPLink Software Configuration Guide
7 • Configuration file handling
When you log in to an IPLink by using the CLI, all commands you enter directly modify the running configu-
ration located in the volatile memory region system: (or RAM) of your IPLink. Because it is located in volatile
memory, to be made permanent, your modifications must be copied to the persistent (non-volatile) memory.
In most cases you will store it as the upcoming startup configuration in the persistent memory region nvram:
under the name startup-config. On the next start-up the system will initialize itself using the modified configu-
ration. After the startup configuration has been saved to persistent memory, you have to restart the IPLink by
using the
reload
command to cause the system to initialize with the new configuration.
The execution command
reload
has been enhanced with the following options:
•
graceful
—reloads the system only if no voice calls are ongoing. If there are voice calls, the system waits until
they all are closed to reload.
•
forced
—reloads the system without prompting for confirmation or for saving the running-configuration
(no need to type yes or no). The question whether to save the running-configuration is automatically
answered with no, the question whether to reload or not with yes.
Mode: Administrator execution
Example:
Modifying the running configuration at the CLI
The following example shows how to modify the currently running configuration via the CLI and save it as the
startup configuration.
IPLink#configure
IPLink(cfg)#…
IPLink(cfg)#copy running-config startup-config
IPLink(cfg)#reload
Press 'yes' to restart, 'no' to cancel : yes
The system is going down
Modifying the running configuration offline
In cases of complex configuration changes, which are easier to do offline, you may store an IPLink’s running
configuration on a TFTP server, where you can edit and save it. Since the IPLink is acting as a TFTP client, it
initiates all file transfer operations.
First, upload the running configuration, named running-config, from the IPLink to the TFTP server. You can
then edit the configuration file located on the TFTP server by using any regular text editor. Once the configu-
ration has been edited, download it back into the IPLink as upcoming startup configuration and store it in the
persistent memory region nvram: under the name startup-config. Finally, restart the IPLink by using the
reload
command to activate the changes.
