This article provides brief information and steps view ASA multiple context.
In ASA multi-context firewalls, there is one admin context and multiple user contexts. The admin context only specifies the interface assignments to each user context, no firewall rule/object definition. The user context contains the firewall rules/object definition and works as a separate firewall. FSM only analyzes the user context.
The admin context also has one special interface for firewall management purpose. The FSM connector can access each user context directly or access the user context through the admin context, for example, connecting to the admin context via the management interface, then switch from the admin context to the user context.
Basically, the FSM connector uses the admin context as a jumper.
FSM treats each user context as a separate firewall. Each user context consumes one license seat.
FSM does NOT analyze the admin context. The admin context config does NOT consume any license seat.
See FSM FAQ for more information.

Use the Cisco Security Appliance using Admin Context only for devices that have multiple devices that are accessible only through the system context. In this instance, the device name or ip address must refer to the Admin context, because that is to which a connection is being sought.
