Controlling Failover
–
Active MAC Address—Identifies the MAC address on the active ASA (usually primary).
–
Standby MAC Address—Identifies the MAC address on the standby ASA (usually secondary).
•Add—Displays the Add/Edit Interface MAC Address dialog box.
•Edit—Displays the Add/Edit Interface MAC Address dialog box for the selected interface.
•Delete—Removes the currently selected interface from the MAC addresses table. There is no
confirmation or undo.

Add/Edit Interface MAC Address

Use the Add/Edit Interface MAC Address dialog box to define the active and standby virtual MAC
addresses for an interface.
Fields
•Physical Interface—Specifies the physical interface for which you are defining failover virtual MAC
addresses. Because the MAC addresses do not change for the LAN failover and Stateful Failover
interfaces during failover, you cannot choose these interfaces.
•MAC Addresses—Contains the fields for specifying the active and standby virtual MAC addresses
for the interface.
–
Active Interface—Specifies the MAC address of the interface on the active ASA (usually
primary). Enter the MAC address in hexadecimal format (for example, 0123.4567.89AB).
–
Standby Interface—Specifies the MAC address of the interface on the standby ASA (usually
secondary). Enter the MAC address in hexadecimal format (for example, 0123.4567.89AB).

Configuring Asymmetric Routing Groups in Multiple Context Mode

Note To configure asymmetric routing (ASR) groups, you must be in the admin context and it must be active.
To configure ASR groups, perform the following steps:
Step1 Choose Configuration > Device Management > Routing > ASR Groups.
Step2 Specify the ASR group IDs of the configured interfaces from the ASR Group ID drop-down list. The
maximum number of groups that you can assign to one interface is eight. If other contexts have assigned
interfaces, to a group, you may assign fewer groups to this context,
Step3 Click Apply to save your changes to the running configuration.
