Guidelines
These guidelines and restrictions apply to dynamic port VLAN membership:

The VTP management domain and the management VLAN of VMPS clients and the VMPS server

Configuring VMPS and Dynamic Port VLAN Membership

These sections describe how to configure VMPS and define dynamic ports on clients:

You must configure VMPS before you configure ports as dynamic.
When you configure a port as dynamic, spanning tree PortFast is enabled automatically for that port.
Automatic enabling of spanning tree PortFast prevents applications on the host from timing out and
entering loops caused by incorrect configurations. You can disable spanning tree PortFast mode on
a dynamic port.
If you reconfigure a port from a static port to a dynamic port on the same VLAN, the port connects
immediately to that VLAN. However, VMPS checks the legality of the specific host on the dynamic
port after a certain period.
Static secure ports cannot become dynamic ports. You must turn off security on the static secure
port before it can become dynamic.
Static ports that are trunking cannot become dynamic ports. You must turn off trunking on the trunk
port before changing it from static to dynamic.
