Network Access (MAC Address Authentication)
– 261 –
■
Max MAC Count
5
– 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
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: 1-2048;
Default: 1024)
◆ Guest VLAN – Specifies the VLAN to be assigned to the port when 802.1X
Authentication or MAC authentication fails. (Range: 0-4094, where 0 means
disabled; Default: Disabled)
The VLAN must already be created and active (see “Configuring VLAN Groups”
on page 153). 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 302).
A port can only be assigned to the guest VLAN in case of failed authentication,
and switchport mode is set to Hybrid. (See “Adding Static Members to VLANs”
on page 156.)
◆ 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. (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)
5. 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.
