Creating a New Context
Each security context will have a unique case-sensitive name, using alphanumeric characters
no longer than 32 characters. The context names are case sensitive, and a context cannot be
assigned either “System” or “Null” as names, as these are reserved by the system. To create
a context, use the context command in global configuration mode:
context [name]
The context command, when executed, will enter into a context configuration submode. In
this configuration mode, interface assignments and the location of the context firewall
configuration file are input.
