Summary Boot Sequence for ASA Evaluating BIOS Options.

This CLI help is useful, quickly becoming part of everyday life for anyone who works with Cisco equipment.

Typing ? after a command, such as show ?, displays the supported parameters for this command. The use of the question mark ( ?), as illustrated in Example 3-2, shows the available commands in a given CLI mode. The symbol > characterizes that the EXEC or nonprivileged mode is in place, meaning that a limited set of tasks can be accomplished. The initial prompt after boot completion is ciscoasa>, in which ciscoasa is the default hostname for the equipment. You do not need to analyze this option because it provides little flexibility. Following a successful load of the OS image, a prompt offering an interactive preconfiguration of the device using menus is presented. Example 3-1 shows a summary of the boot process for an ASA 5505 appliance whose factory settings have not been changed yet. Before dealing with any specific configuration procedure for the Adaptive Security Appliance (ASA), you need to understand a set of basic concepts.
