VMPS Database Configuration File Example

This example shows a sample VMPS database configuration file as it appears on a VMPS server. A

VMPS database configuration file is an ASCII text file that is stored on a TFTP server accessible to the

switch that functions as the VMPS server.

! The VMPS domain must be defined.

!vmps mode { open | secure }

! The default mode is open.

!vmps fallback <vlan-name>

!vmps no-domain-req { allow | deny }

! The default value is allow.
