3. Observe the switch's performance with the new parameter settings to
verify the effect of your changes.
4. When you are satisfied that you have the correct parameter settings, use
the command to copy the changes to the startup-config file.
write memory
Syntax: write memory
Saves the running configuration file to the startup-config.
The saved configuration becomes the boot-up configuration
of the switch on the next boot.
For example, the default port mode setting is
uses Cat 3 wiring and you want to connect the switch to another autosensing
device capable of 100 Mbps operation. Because 100 Mbps over Cat 3 wiring
can introduce transmission problems, the recommended port mode is
which allows the port to negotiate full- or half-duplex, but restricts speed to
10 Mbps. The following command configures port A5 to auto-10 mode in the
running-config file, allowing you to observe performance on the link without
making the mode change permanent.
ProCurve(config)# interface e a5 speed-duplex auto-10
After you are satisfied that the link is operating properly, you can save the
change to the switch's permanent configuration (the startup-config file) by
executing the following command:
ProCurve(config)# write memory
The new mode ( auto-10 ) on port A5 is now saved in the startup-config file, and
the startup-config and running-config files are identical. If you subsequently
reboot the switch, the auto-10 mode configuration on port A5 will remain
because it is included in the startup-config file.
How To Cancel Changes You Have Made to the Running-Config File.
If you use the CLI to change parameter settings in the running-config file, and
then decide that you don't want those changes to remain, you can use either
of the following methods to remove them:
■ Manually enter the earlier values you had for the changed settings. (This
is recommended if you want to restore a small number of parameter
settings to their previous boot-up values.)
Update the running-config file to match the startup-config file by reboot­
■
ing the switch. (This is recommended if you want to restore a larger
number of parameter settings to their previous boot-up values.)
