Configuring Failover with the High Availability and Scalability Wizard
Although you can create security contexts on this screen, you cannot assign interfaces to those contexts
or configure any other properties for them. To configure context properties and assign interfaces to a
context, you need to use the System > Security Contexts pane.
Fields
• Name—Displays the name of the security context. To change the name, click the name and type a
new name.
• Failover Group—Displays the failover group the context is assigned to. To change the failover group
for a security context, click the failover group and select the new failover group number from the
drop-down list.
Modes
The following table shows the modes in which this feature is available:
Failover Link Configuration
The Failover Link Configuration screen only appears if you are configuring LAN-based failover; it does
not appear if you are configuring a PIX 500 series security appliance for cable-based failover.
Fields
• LAN Interface—Choose the interface to use for failover communication from the drop-down list.
• Logical Name—Type a name for the interface.
• Active IP—Type the IP address used for the failover link on the unit that has failover group 1 in the
active state.
• Standby IP—Type the IP address used for the failover link on the unit that has failover group 1 in
the standby state.
• Subnet Mask—Type or select a subnet mask for the Active IP and Standby IP addresses.
• Secret Key—(Optional) Enter the key used to encrypt failover communication. If this field is left
blank, failover communication, including any passwords or keys in the configuration sent during
command replication, is in clear text.
