Configuring MAC Authentication for Ports
Configures MAC authentication on switch ports, including setting the maximum MAC
count, applying a MAC address filter, and enabling dynamic VLAN assignment.
Command Attributes
• Mode – Enables MAC authentication on a port. (Default: None)
• Maximum MAC Count – Sets the maximum number of MAC addresses that can
be authenticated on a port. The maximum number of MAC addresses per port is
2048, 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 failed. (Default: 2048; Range: 1 to 2048)
• Guest VLAN – Specifies the VLAN to be assigned to the port when MAC
Authentication of 802.1X Authentication fails. The VLAN must already be created
and active. (Default: Disabled; Range: 1 to 4094)
• 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.) 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. (Default: Enabled)
