Purpose
Merges the startup configuration with the running configuration. A merge
adds any new commands from the new configuration to the running
configuration. If the configurations are the same, no changes occur. If
commands conflict or if commands affect the running of the context, then
the effect of the merge depends on the command. You might get errors, or
you might have unexpected results.
Reloads the ASA, which loads the startup configuration and discards the
running configuration.
Loads the startup configuration and discards the running configuration
without requiring a reload.
Purpose
Views the running configuration.
Views the running configuration of a specific command.
Views the startup configuration.
Purpose
Clears all the configuration for a specified command. If you only want to
clear the configuration for a specific version of the command, you can
enter a value for level2configurationcommand.
For example, to clear the configuration for all aaa commands, enter the
following command:
hostname(config)# clear configure aaa
To clear the configuration for only aaa authentication commands, enter
the following command:
hostname(config)# clear configure aaa authentication
Disables the specific parameters or options of a command. In this case, you
use the no command to remove the specific configuration identified by
qualifier.
For example, to remove a specific nat command, enter enough of the
command to identify it uniquely as follows:
hostname(config)# no nat (inside) 1
