sections:

• Firewall Mode and Security Context Mode, page C-1

• Command Modes and Prompts, page C-2

Note The CLI uses similar syntax and other conventions to the Cisco IOS CLI, but the security appliance

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 security appliance.

Firewall Mode and Security Context Mode

The security appliance runs in a combination of the following modes:

• Transparent firewall or routed firewall mode

The firewall mode determines if the security appliance runs as a Layer 2 or Layer 3 firewall.

• Multiple context or single context mode

The security context mode determines if the security appliance runs as a single device or as multiple

security contexts, which act like virtual devices.

Some commands are only available in certain modes.
