Quick Reference Guide

Getting Started | 57
When the switch is booted, its configuration is managed by the startup configuration (“startup-config”) file
that is stored in non-volatile memory (NVRAM). As you make configuration changes, those changes are
stored in volatile system memory as the “running config” until you copy them to the startup-config. The
quickest way to do that is to use the
write memory command (executed from the Privileged Exec mode).
You can also use the command
copy system:running-config nvram:startup-config. For more detail, see
Saving the Running Configuration on page 49.
Beginning with SFTOS Version 2.3, making changes to the startup-config file causes that file to be stored
as a text file. A major benefit of that text file, in addition to faster reboots, is that you can edit the file after
you copy it to a TFTP server. You can then download the edited file to any switch to use as the
startup-config file.
Clearing the Running Configuration
When downloading the startup-config file to the system from a TFTP server, the file will not take effect as
the startup configuration of the switch until a reboot (
reload) is performed. However, you have the option
of using the
clear config command, followed by the script apply startup-config command to use the newly
downloaded startup-config without rebooting the switch. For details in this chapter on using script
commands, see Using Configuration Scripts on page 60.
The following example shows the
clear config command for clearing the running-config from memory:
Figure 3-28. Clearing the Running Configuration
Saving the Startup Configuration to the Network
The following is an example of how to save the startup configuration to a TFTP site on the network.
Caution: Beginning with Version 2.3, the following commands must be present and occur in the same
relative locations in the startup-config file as if they had been automatically generated. Failure to do so will
result in unpredictable behavior:
interface vlan vlan id
vlan configuration commands
exit
configure
stack member commands (for example
member unit switchindex)
exit
