ASA and FXOS Management
The ASA and FXOS operating systems share the Management 1/1 interface. This interface has separate IP addresses for connecting to ASA and to FXOS.
This interface is called Management 1/1 in the ASA; in FXOS, you might see it displayed as MGMT, management0, or other similar names. This guide refers to this interface as Management 1/1 for consistency and simplicity.
Some functions must be monitored on FXOS and others on the ASA, so you need to make use of both operating systems for ongoing maintenance. For initial configuration on FXOS, you can connect to the default 192.168.45.45 IP address using SSH or your browser (https://192.168.45.45).
For initial configuration of the ASA, you can connect using ASDM to https://192.168.45.1/admin. In ASDM, you can later configure SSH access from any interface.
Both operating systems are available from the console port. Initial connection accesses the FXOS CLI. You can access the ASA CLI using the connect asa command.
You can also allow FXOS management from ASA data interfaces; configure SSH, HTTPS, and SNMP access. This feature is useful for remote management.
