These restrictions apply to dynamic-access ports:

The software implements the VLAN Query Protocol (VQP) client, which can query a VMPS such

as a Catalyst 6000 series switch. The Catalyst 3750-X and 3560-X switches are not VMPS servers.

The VMPS server must be configured before a port is configured as dynamic.

Use dynamic-access ports only to connect end stations. Connecting them to switches or routers (that

use bridging protocols) can cause a loss of connectivity.

Configure the network so that STP does not put the dynamic-access port into an STP blocking state.

The Port Fast feature is automatically enabled on dynamic-access ports.

Dynamic-access ports can only be in one VLAN and do not use VLAN tagging.

Dynamic-access ports cannot be configured as

Members of an EtherChannel port group (dynamic-access ports cannot be grouped with any

other port, including other dynamic ports).

Source or destination ports in a static address entry.

Monitor ports.

This example shows how to change a switched port interface that is operating in access mode to operate

in VLAN 2 instead of the default VLAN:

Switch(config-if)# switchport access vlan 2

You can verify your setting by entering the show interfaces interface-id switchport privileged EXEC

command and examining information in the Administrative Mode and Operational Mode rows.
