Modes in saving the configuration
z
Fast saving mode. This is the mode when you use the
save
command without the
safely
keyword.
The mode saves the file quicker but is likely to lose the original configuration file if the switch
reboots or the power fails during the process.
z
Safe mode. This is the mode when you use the
save
command with the
safely
keyword. The mode
saves the file slower but can retain the original configuration file in the switch even if the switch
reboots or the power fails during the process.
When you use the
save safely
command to save the configuration file, if the switch reboots or the
power fails during the saving process, the switch initializes itself in the following two conditions when it
starts up next time:
z
If a configuration file with the extension
.cfg
exists in the Flash, the switch uses the configuration
file to initialize itself when it starts up next time.
z
If there is no
.cfg
configuration file in the Flash, but there is a configuration file with the
extension
.cfgbak
(backup configuration file containing the original configuration information)
or/and a configuration file with the extension
.cfgtmp
(temporary configuration file containing the
current configuration information) in the Flash, you can change the extension
.cfgbak
or
.cfgtmp
to
.cfg
using the
rename
command. The switch will use the renamed configuration file to initialize
itself when it starts up next time.
For details of the
rename
command, refer to the
File System Management
part of the manual.
Three attributes of the configuration file
z
Main attribute. When you use the
save
[ [
safely
] [
main
] ] command to save the current
configuration, the configuration file you get has main attribute. If this configuration file already
exists and has backup attribute, the file will have both main and backup attributes after execution of
this command. If the filename you entered is different from that existing in the system, this
command will erase its main attribute to allow only one main attribute configuration file in the
switch.
z
Backup attribute. When you use the
save
[
safely
]
backup
command to save the current
configuration, the configuration file you get has backup attribute. If this configuration file already
exists and has main attribute, the file will have both main and backup attributes after execution of
this command. If the filename you entered is different from that existing in the system, this
command will erase its backup attribute to allow only one backup attribute configuration file in the
switch.
z
Normal attribute. When you use the
save
cfgfile
command to save the current configuration, the
configuration file you get has normal attribute if it is not an existing file. Otherwise, the attribute is
dependent on the original attribute of the file.
