Replacing The Startup Configuration With The Running Configuration; Copying A Configuration File To Or From A Tftp Server - Foundry Networks FESX Manual

Foundry Configuration Guide for the FESX, FSX, and FWSX
To display this file, enter the show configuration command at any CLI prompt.
• Running configuration file – This file contains the configuration active in the system RAM but not yet saved
to flash. These changes could represent a short-term requirement or general configuration change. To
display this file, 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 file. The startup configuration
file is shared by both flash modules. The running configuration file resides in DRAM.
When you load the startup-config file, the CLI parses the file three times.
1. During the first pass, the parser searches for system-max commands. A system-max command changes
the size of statically configured memory.
2. During the second pass, the parser implements the system-max commands if present and also implements
trunk configuration commands (trunk command) if present.
3. During the third pass, the parser implements the remaining commands.

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 flash
memory. When you write configuration changes to flash memory, 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:
FESX424 Switch# write memory
Replacing the Running Configuration with the Startup Configuration
If 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:
FESX424 Switch# reload
Logging Changes to the Startup-Config File
You can configure a Foundry device to generate a Syslog message when the startup-config file is changed. The
trap is enabled by default.
The following Syslog message is generated when the startup-config file is changed:
startup-config was changed
If the startup-config file was modified by a valid user, the following Syslog message is generated:
startup-config was changed by <username>
To disable or re-enable Syslog messages when the startup-config file is changed, use the following command:
Syntax: [no] logging enable config-changed

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 a Foundry device, 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 using the CLI, enter one of the following
commands:
• copy startup-config tftp <tftp-ip-addr> <filename> – Use this command to upload a copy of the startup
configuration file from the Layer 2 Switch or Layer 3 Switch to a TFTP server.
