Configuring VMPS
Default VMPS Client Configuration
Table 11-6 shows the default VMPS and dynamic-access 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-access ports.
• IEEE 802.1x ports cannot be configured as dynamic-access ports. If you try to enable IEEE 802.1x
on a dynamic-access (VQP) port, an error message appears, and IEEE 802.1x is not enabled. If you
try to change an IEEE 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.
• Dynamic-access ports cannot be monitor ports.
• Secure ports cannot be dynamic-access ports. You must disable port security on a port before it
becomes dynamic.
• Private VLAN ports cannot be dynamic-access ports.
• Dynamic-access ports cannot be members of an EtherChannel group.
• Port channels cannot be configured as dynamic-access ports.
Configuring the VMPS Client
You configure dynamic VLANs by using the VMPS (server). The switch can be a VMPS client; it cannot
be a VMPS server.
