MAC-based Access Control (MAC)
MAC-based access control is a method to authenticate and authorize access using either a port or host. For port-
based MAC-based access control, the method decides port access rights, while for host-based MAC-based access
control, the method determines the MAC access rights.
A MAC user must be authenticated before being granted access to a network. Both local authentication and remote
RADIUS server authentication methods are supported. In MAC-based access control, MAC user information in a
local database or a RADIUS server database is searched for authentication. Following the authentication result,
users achieve different levels of authorization.
Notes about MAC-based Access Control
There are certain limitations and regulations regarding MAC-based access control:
1. Once this feature is enabled for a port, the Switch will clear the FDB of that port.
2. If a port is granted clearance for a MAC address in a VLAN that is not a Guest VLAN, other MAC
addresses on that port must be authenticated for access and otherwise will be blocked by the Switch.
3. Ports that have been enabled for Link Aggregation and Port Security cannot be enabled for MAC-based
Authentication.
4. Ports that have been enabled for GVRP cannot be enabled for Guest VLAN.
MAC-based Access Control Settings
This window is used to set the parameters for the MAC-based access control function on the Switch. The user can
set the running state, method of authentication, RADIUS password, view the Guest VLAN configuration to be
associated with the MAC-based access control function of the Switch, and configure ports to be enabled or
disabled for the MAC-based access control feature of the Switch. Please remember, ports enabled for certain other
features, listed previously, and cannot be enabled for MAC-based access control.
To view this window, click
Security > MAC-based Access Control (MAC) > MAC-based Access Control
