When enabled, the VLAN identifiers returned by the RADIUS server will be 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 same VLAN configuration, or they are treated as an authentication failure.
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 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.
Example
The following
Example enables dynamic VLAN assignment on port 1.
Console(config)#interface ethernet 1/1
Console(config-if)#network-access dynamic-vlan
Console(config-if)#
network-access guest-vlan
Use this command to assign all traffic on a port to a guest VLAN when network access (MAC authentication) or 802.1X
authentication is rejected. Use the no form of this command to disable guest VLAN assignment.
Syntax
network-access guest-vlan vlan-id
no network-access guest-vlan
Default Setting
Disabled
Command Mode
Interface Configuration
Command Usage
The VLAN to be used as the guest VLAN must be defined and set as active (see “vlan database” on page 4-225).
When used with 802.1X authentication, the intrusion-action must be set for “guest-vlan” to be effective (see “dot1x
intrusion-action”).
Example
Console(config)#interface ethernet 1/1
Console(config-if)#network-access guest-vlan 25
Console(config-if)#
