Network Access (MAC Address Authentication)

– 334 –

P

ARAMETERS

These parameters are displayed:

MAC Authentication

Status – Enables MAC authentication on a port. (Default: Disabled)

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)

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)

Network Access Max MAC Count

6

– 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 200

). Also, when used with 802.1X authentication,

intrusion action must be set for “Guest VLAN” (see

"Configuring Port

Settings for 802.1X" on page 385

).

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.

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

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.
