Network Access (MAC Address Authentication)

Configuring Network Access for Ports
Use the Security > Network Access (Configure Interface - General) page to configure MAC
authentication on switch ports, including enabling address authentication, setting the maximum
MAC count, and enabling dynamic VLAN or dynamic QoS assignments.

Parameters
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 17 – 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
17
– 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: 1-2048; 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 722).
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 890).
• 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, 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)
17. 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.
