Network Access (MAC Address Authentication)
– 301 –
◆ Network Access Max MAC Count
5
– Sets the maximum number of
MAC addresses that can be authenticated on a port interface via all
forms of authentication (including Network Access and IEEE 802.1X).
(Range: 1-1024; Default: 1024)
◆ Guest VLAN – Specifies the VLAN to be assigned to the port when
802.1X Authentication fails. (Range: 0-4093, where 0 means disabled;
Default: Disabled)
The VLAN must already be created and active (see "Configuring VLAN
Groups" on page 170). Also, when used with 802.1X authentication,
intrusion action must be set for “Guest VLAN” (see "Configuring Port
Authenticator Settings for 802.1X" on page 345).
◆ Dynamic VLAN – Enables dynamic VLAN assignment for an
authenticated port. When enabled, any VLAN identifiers returned by the
RADIUS server through the 802.1X authentication process are applied
to the port, providing the VLANs have already been created on the
switch. (GVRP is not used to create the VLANs.) (Default: Enabled)
The VLAN settings specified by the first authenticated MAC address are
implemented for a port. Other authenticated MAC addresses on the
port must have the same VLAN configuration, or they are treated as
authentication failures.
If dynamic VLAN assignment is enabled on a port and the RADIUS
server returns no VLAN configuration (to the 802.1X authentication
process), the authentication is still treated as a success, and the host is
assigned to the default untagged VLAN.
When the dynamic VLAN assignment status is changed on a port, all
authenticated addresses mapped to that port are cleared from the
secure MAC address table.
◆ Dynamic QoS – Enables dynamic QoS assignment for an
authenticated port. (Default: Disabled)
◆ MAC Filter ID – Allows a MAC Filter to be assigned to the port. MAC
addresses or MAC address ranges present in a selected MAC Filter are
exempt from authentication on the specified port (as described under
"Configuring a MAC Address Filter"). (Range: 1-64; Default: None)
WEB INTERFACE
To configure MAC authentication on switch ports:
1. Click Security, Network Access.
2. Select Configure Interface from the Step list.
3. Click the General button.
4. Make any configuration changes required to enable address
authentication on a port, set the maximum number of secure addresses
supported, the guest VLAN to use when MAC Authentication or 802.1X
Authentication fails, and the dynamic VLAN and QoS assignments.
