"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:

HP4108(config)# interface ethernet 5 disable

The above command disables port 5 in the running-config file, but not in the
startup-config file. Port 5 remains disabled only until the switch reboots. If
you want port 5 to remain disabled through the next reboot, use

write memory

to save the current running-config file to the startup-config file in flash
memory.

HP4108(config)# write memory

Storing and Retrieving Configuration Files.

You can store or retrieve a

backup copy of the startup-config file on another device. For more informa-
tion, see appendix A, "Transferring an Operating System or Startup-Config
File"

Using the CLI To Implement
Configuration Changes

The CLI offers these capabilities:

Access to the full set of switch configuration features

The option of testing configuration changes before making them perma-
nent

How To Use the CLI To View the Current Configuration Files.

Use

show

commands to view the configuration for individual features, such as port

status or Spanning Tree Protocol. However, to view either the entire startup-
config file or the entire running-config file, use the following commands:

show startup-config

: Displays the current startup-config file.

write terminal

: Displays the current running-config file.

N o t e

The

show startup-config

and

write terminal

commands display the configuration

settings that differ from the switch’s factory-default configuration.
