LevelOne AMG-2100 User Manual page 11

On-demand User is a type of user with its account credential stored in a database named
"On-demand" within AMG-2100/AMG-2101. The "On-demand" database of AMG-2100/AMG-2101
allows on-demand account records. On-demand User is used for short term usage purpose; it has an
expiration period. An on-demand account record will be recycled for creating new on-demand account
if it has expired for over certain days or has been modified by the Administrator/Manager manually.
External Authentication Database is a user account database that is not built inside
AMG-2100/AMG-2101. Besides Local database and On-demand database, AMG-2100/AMG-2101
allows up to three additional External Authentication databases simultaneously. The types of external
Authentication databases supported are RADIUS, POP3, LDAP (including ActiveDirectory), and
NTDomain (Win2K's NTDS). The database of another AMG Series device can be used as an external
RADIUS database. External Authentication Database is useful for implementing account roaming; for
example, multiple AMG-2100/AMG-2101 devices in multiple campuses can share one common external
database. A user needs only one account in the common database to access the network from different
campuses.
Service Zone is a logic partition of AMG-2100/AMG-2101's LAN network. The concept of Service Zone
is similar to the concept of virtual LAN (VLAN), which can be used to group the network traffic or
network services for clients on the same VLAN segment, regardless of the clients' physical locations.
That is, several VLAN segments may be in service at one physical network location while devices
belonging to one VLAN segment may appear in multiple physical locations.
Each Service Zone can also be viewed a virtual machine of AMG-2100/AMG-2101 because each Service
Zone can define its own customized login portal page, and its own gateway properties (such as LAN IP
address, DHCP on/off and address range). The feature of Multiple Service Zone is also useful to service
multiple hotspot franchises in shopping malls or airport terminals by a single AMG-2100/AMG-2101.
A Service Zone is uniquely defined by a VLAN tag id and an associated SSID attribute. When a managed
access point (MAP) is added to a Service Zone through AMG-2100/AMG-2101 by the administrator, the
associated SSID will be activated in the MAP along with the VLAN tag of the Service Zone.
For example, in the following Figure 2, the administrator plans three logical Service Zones for an
academic campus:
The first Service Zone (with SSID='Student", and VLAN tag=1) is for students.
The second (with SSID="Faculty" and VLAN tag=2) for faculties.
The third (SSID="Guest" and VLAN tag=3) for guests.
