Example 6: Secondary FWSM System Configuration

You do not need to configure any contexts, just the following minimal configuration for the system.
You must first enable multiple context mode using the mode multiple command. Then enter the
activation key to allow more than two contexts using the activation-key command. The mode and the
activation key are not stored in the configuration file, even though they do endure reboots. If you view
the configuration on the FWSM using the write terminal, show startup, or show running commands,
the mode displays after the FWSM Version (blank means single mode, "<system>" means you are in
multiple mode in the system configuration, and <context> means you are in multiple mode in a context).

Example 6: Switch Configuration

The following lines in the Cisco IOS switch configuration on both switches relate to the FWSM. For
information about configuring redundancy for the switch, see the switch documentation.
