Security Context Overview

You can partition a single FWSM into multiple virtual devices, known as security contexts. Each context
has its own security policy, interfaces, and administrators. Multiple contexts are similar to having
multiple standalone devices. Many features are supported in multiple context mode, including routing
tables, firewall features, and management. Some features are not supported, including most dynamic
routing protocols.
