Command Usage
â—†
When enabled, the VLAN identifiers returned by the RADIUS server through the
802.1X authentication process will be applied to the port, providing the VLANs
have already been created on the switch.
â—†
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.
â—†
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.
â—†
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)#
