Advanced Settings Dialog Box
The Advanced Settings dialog box lets you configure additional failover settings for the selected FWSM.
Note The following reference table describes all fields that can be presented in the Advanced Settings dialog
box. The fields actually presented depend on operating mode (routed or transparent) and whether the
device is hosting single or multiple contexts.
Navigation Path
You can access the Advanced Settings dialog box by clicking the Settings button on the Failover Page
(FWSM), page 49-12.

Shared Key (FWSM 3.1.1+ only)
The options in this section let you encrypt the communications between the active and standby devices
by providing a shared encryption key.
Caution All information sent over the failover and Stateful Failover links is sent in clear text unless
you secure the communication with a failover key. If this device is used to terminate VPN
tunnels, this information includes any user names, passwords and shared keys used for
establishing the tunnels. Transmitting this sensitive data in clear text could pose a significant
security risk. We recommend securing the failover communications with a shared key.
Shared Key
Confirm
Enter any string of characters up to 63 numbers, letters and punctuation
characters. This string is used to generate the encryption key.
Re-enter this string the Confirm field.
If you select HEX, the entry in the Shared Key and Confirm fields must
be exactly 32 hexadecimal characters (0-9, a-f).
Interface Configuration
This table is presented on the Failover page for devices operating in single-context mode, or for
individual security contexts only.
The table lists all available named interfaces. To enable or disable monitoring of an interface, select it
in the list and click the Edit Row button to open the Edit Failover Interface Configuration Dialog Box,
page 49-23. Select or deselect Monitor this interface for failure.
