Merging saved and running configurations
How to merge saved and running configurations, and other configuration details.
You can merge a saved configuration with the active (running) configuration by using the merge command. An example is provided in merge.
The merger adds new configuration entries and applies any modifications to existing active entries to produce a new working configuration. This merged configuration must be committed before it becomes the active configuration.
Configuration can be loaded from a hard disk (including a Flash disk or USB device), a TFTP server, an FTP server, an SCP server, or an HTTP server. Note that you cannot load an empty configuration file; the configuration file must contain at least one configuration node.
