Startup-config File:

Exists in flash (non-volatile) memory and is used

to preserve the most recently-saved configuration as the “permanent”
configuration.

Rebooting the switch replaces the current running-config file with a new
running-config file that is an exact copy of the current startup-config file.

N o t e

Any of the following actions reboots the switch:

Executing the

boot

or the

reload command in the CLI

Executing the

Reboot

command in the menu interface

Pressing the Reset button on the front of the switch

Removing, then restoring power to the switch

Options for Saving a New Configuration.

Making one or more changes

to the running-config file creates a new operating configuration. Saving a new
configuration means to overwrite (replace) the current startup-config file with
the current running-config file. This means that if the switch subsequently
reboots for any reason, it will resume operation using the new configuration
instead of the configuration previously defined in the startup-config file. There
are three ways to save a new configuration:

In the CLI:

Use the

write memory

command. This overwrites the current

startup-config file with the contents of the current running-config file.

In the menu interface:

Use the

Save

command. This overwrites both the

running-config file and the startup-config file with the changes you have
specified in the menu interface screen.

In the web browser interface:

Use the [Apply Changes] button or other

appropriate button. This overwrites both the running-config file and the
startup-config file with the changes you have specified in the web browser
interface window.

Note that using the CLI instead of the menu or web browser interface gives
you the option of changing the running configuration without affecting the
startup configuration. This allows you to test the change without making it
“permanent”. When you are satisfied that the change is satisfactory, you can
make it permanent by executing the

write memory

command. For example,

suppose you use the following command to disable port 5:

SMC TigerSwitch 10/100(config)# interface ethernet 5

disable
