reload command
The
reload
CLI command provides you with a configuration rollback
mechanism to prevent loss of connectivity to a switch, typically for remote
configurations. The
reload
command allows you to temporarily disable the
autosave feature for a specified time period (1 to 60 minutes), allowing you to
make a number of configuration changes on remote switches without affecting the
current saved configuration.
During the interval in which the autosave feature is disabled by the
reload
command, you must use the
copy config nvram, write mem
, or
save config
command to force a manual save of your configurations.
Once the reload timer expires, the switch reloads the last saved configuration. To
abort the switch reload before the timer expires, you must enter the
reload cancel
command.
The
reload
command provides you with a safeguard against any
misconfigurations when you perform dynamic configuration changes on a remote
switch.
The following example describes how you can use the
reload
command to
prevent connectivity loss to a remote switch.
1
Enter the CLI command
reload force 30
. This instructs the switch to
reboot in 30 minutes, loading the configuration from NVRAM.
During this 30-minute period, autosave of the configuration to NVRAM is
disabled.
2 Execute dynamic switch configuration commands, which take effect
immediately. These configurations are not saved to NVRAM.
