Default VMPS Configuration
Table 12-7 shows the default VMPS and dynamic port configuration on client switches.
VMPS Configuration Guidelines
These guidelines and restrictions apply to dynamic access port VLAN membership:
• You should configure the VMPS before you configure ports as dynamic.
• The communication between a cluster of switches and VMPS is managed by the command switch
and includes port-naming conventions that are different from standard port names. For the
cluster-based port-naming conventions, see the “VMPS Database Configuration File” section on
page 12-28.
• When you configure a port as a dynamic access port, the spanning-tree Port Fast feature is
automatically enabled for that port. The Port Fast mode accelerates the process of bringing the port
into the forwarding state.
• 802.1X ports cannot be configured as dynamic access ports. If you try to enable 802.1X on a
dynamic-access (VQP) port, an error message appears, and 802.1X is not enabled. If you try to
change an 802.1X-enabled port to dynamic VLAN assignment, an error message appears, and the
VLAN configuration is not changed.
• Trunk ports cannot be dynamic access ports, but you can enter the switchport access vlan dynamic
interface configuration command for a trunk port. In this case, the switch retains the setting and
applies it if the port is later configured as an access port. You must turn off trunking on the port
before the dynamic access setting takes effect.
