Check the amount of free memory on the ASA by doing the following:
•
•
In a failover configuration, the two units must have the same hardware configuration. They must be the

Management 0/0 Interface on the ASA 5500-X Series
You manage the ASA through the Management 0/0 interface on the ASA 5512-X through ASA 5555-X
models. The Management 0/0 interface has the following characteristics:

By default, the Management 0/0 interface is configured for management-only traffic, and you cannot
disable management-only for the Management interface. Also, the ASA 5500-X models do not allow
subinterfaces on the Management interface, so for per-context management, you must connect to a data
interface.
The Management 0/0 interface is configured for ASDM access as part of the default factory
configuration.
