Hi Swen
Mr. Osio war genau richtig. Du kannst einen VMPS Server aber auch mit CISCO WORKS realisieren. Auch andere Größere Switche (5000 5500) können VMPS. Ohne VMPS geht die dynamische zuordnung VLAN-MAC bei CISCO nicht. (Beim Link nach VMPS suchen)

Understanding VMPS
When the VMPS receives a VQP request from a client switch, it searches its database for a MAC-address-to-VLAN mapping. The server response is based on this mapping and whether or not the server is in secure mode. Secure mode determines whether the server shuts down the port when a VLAN is not allowed on it or just denies the port access to the VLAN
Dynamic Port VLAN Membership
A dynamic (nontrunking) port on the switch can belong to only one VLAN, with a VLAN ID from 1 to 1005. When the link comes up, the switch does not forward traffic to or from this port until the VMPS provides the VLAN assignment. The VMPS receives the source MAC address from the first packet of a new host connected to the dynamic port and attempts to match the MAC address to a VLAN in the VMPS database
VMPS Database Configuration File
The VMPS contains a database configuration file that you create. This ASCII text file is stored on a switch-accessible TFTP server that functions as a VMPS server. The file contains VMPS information, such as the domain name, the fallback VLAN name, and the MAC-address-to-VLAN mapping. The switch cannot act as the VMPS, but you can use a Catalyst 5000 or Catalyst 6000 series switch as the VMPS
