Adding a Security Context
For more information about security contexts, see the “Security Context Overview” section on
page 10-1.
To add a security context, perform the following steps:
Step 1 If you are not already in the System configuration mode, in the Device List pane, double-click System
under the active device IP address.
Step 2 On the Context Management > Security Contexts pane, click Add.
The Add Context dialog box appears.
Step 3 In the Security Context field, enter the context name as a string up to 32 characters long.
This name is case sensitive, so you can have two contexts named “customerA” and “CustomerA,” for
example. “System” or “Null” (in upper or lower case letters) are reserved names, and cannot be used.
Step 4 In the Interface Allocation area, click the Add button to assign an interface to the context.
