Note The CLI uses similar syntax and other conventions to the Cisco IOS CLI, but the ASA operating system
is not a version of Cisco IOS software. Do not assume that a Cisco IOS CLI command works with or has
the same function on the ASA.
Firewall Mode and Security Context Mode
The ASA runs in a combination of the following modes:
• Transparent firewall or routed firewall mode
The firewall mode determines if the ASA runs as a Layer 2 or Layer 3 firewall.
• Multiple context or single context mode
The security context mode determines if the ASA runs as a single device or as multiple security
contexts, which act like virtual devices.
Some commands are only available in certain modes.
