Network Access (MAC Address Authentication)
– 299 –
P
ARAMETERS
These parameters are displayed in the web interface:
u
MAC Authentication
n
Status
– Enables MAC authentication on a port. (Default: Disabled)
n
Intrusion
– Sets the port response to a host MAC authentication
failure, to either block access to the port or to pass traffic through.
(Options: Block, Pass; Default: Block)
n
Max MAC Count
6
– Sets the maximum number of MAC addresses
that can be authenticated on a port via MAC authentication; that is,
the Network Access process described in this section.
(Range: 1-1024; Default: 1024)
u
Network Access Max MAC Count
– 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)
u
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
). Also, when used with 802.1X authentication,
intrusion action must be set for “Guest VLAN” (see
Settings for 802.1X" on page 349
).
u
Dynamic VLAN
– Enables dynamic VLAN assignment for an
authenticated port. When enabled, any VLAN identifiers returned by the
RADIUS server 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, 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 are cleared from the secure MAC address
table.
u
Dynamic QoS
– Enables dynamic QoS assignment for an
authenticated port. (Default: Disabled)
u
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
6.
The maximum number of MAC addresses per port is 1024, and the maximum number of
secure MAC addresses supported for the switch system is 1024. When the limit is
reached, all new MAC addresses are treated as authentication failures.
