You can upload either the startup configuration file or the running configuration to
the TFTP server, or code flash and use in booting the system.
v
Startup configuration file - This file (startup-config) contains the configuration
information that is currently saved in the code flash. To display this file, enter
the
show configuration
command at any CLI prompt.
v Running configuration - This active configuration is in the system RAM but not
yet saved to code flash. These changes could represent a short-term requirement
or general configuration change. To display this configuration, enter the
show
running-config or write terminal command at any CLI prompt.
Each device can have one startup configuration file and one running configuration.
The startup configuration file is shared by both flash modules. The running
configuration resides in DRAM.
Replacing the startup configuration with the running
configuration
After you make configuration changes to the active system, you can save those
changes by writing them to code flash. When you write configuration changes to
code flash, you replace the startup configuration with the running configuration.
To replace the startup configuration with the running configuration, enter the
following command at any Enable or CONFIG command prompt:
NetIron# write memory
Replacing the running configuration with the startup
configuration
If you haven’t yet executed a write memory command to overwrite the startup
configuration with the running configuration and you want to back out of the
changes you have made to the running configuration and return to the startup
configuration, enter the following command at the Privileged EXEC level of the
CLI:
NetIron# reload
When the system detects differences between the running and startup
configurations, it prompts you as follows:
Running Config data has been changed. Do you want to continue
the reload without saving the running config? (enter 'y' or 'n'):
Enter
y
, and press the Enter key
Copying a configuration file to or from a TFTP server
To copy the startup-config or running-config file to or from a TFTP server, use one
of the following methods.
Note: You can name the configuration file when you copy it to a TFTP server.
However, when you copy a configuration file from the server to the switch,
the file is always copied as ”startup-config“ or ”running-config“, depending
on which type of file you saved to the server.
To initiate transfers of configuration files to or from a TFTP server, enter one of the
following commands at the Privileged EXEC level of the CLI:
v copy startup-config tftp <tftp-ip-addr> <filename>
- Use this command to
upload a copy of startup-config from the switch to a TFTP server.
