C HAPTER 24 | General Security Measures
Network Access (MAC Address Authentication)
– 670 –
◆ While a port has an assigned dynamic QoS profile, any manual QoS
configuration changes only take effect after all users have logged off of
the port.
N OTE : Any configuration changes for dynamic QoS are not saved to the
switch configuration file.
EXAMPLE
The following example enables the dynamic QoS feature on port 1.
Console(config)#interface ethernet 1/1
Console(config-if)#network-access dynamic-qos
Console(config-if)#
network-access
dynamic-vlan
Use this command to enable dynamic VLAN assignment for an
authenticated port. Use the no form to disable dynamic VLAN assignment.
SYNTAX
[no] network-access dynamic-vlan
DEFAULT SETTING
Enabled

Interface Configuration
COMMAND USAGE
◆ 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. 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.
