Property Value
dbo:abstract VMPS (VLAN Management Policy Server) ist ein Cisco-Switch, welcher die Zuordnung zwischen MAC-Adresse und VLAN von Netzwerkendgeräten verwaltet. Für Anfragen von dezentralen Switches an den VMPS-Master wird das verwendet. Mit Hilfe von VMPS werden Ports basierend auf der MAC-Adresse des angeschlossenen Gerätes dynamisch einem VLAN zugeordnet. Somit kann ein Gerät an einem beliebigen Punkt des Netzwerkes angebunden werden und wird vom Switch automatisch dem zugeordneten VLAN zugeordnet. Die Administration erfolgt im einfachsten Fall mittels Textdatei, die via TFTP auf den VMPS-Master hochgeladen wird. Switchports, an denen ein Gerät mit unbekannter MAC-Adresse angeschlossen ist, können entweder gesperrt oder einem speziellen Fallback- oder Guest-VLAN zugeordnet und so vom Produktivnetzwerk isoliert werden. (de) A VLAN Management Policy Server (VMPS) is a network switch that contains a mapping of device information to VLAN. The primary goal of VMPS is VLAN assignment for general network management purposes, but can also be used for providing security through segregating clients with an unknown MAC address, or through further extension of the protocol to provide login for Cisco ACLs. This last functionality is now deprecated by Cisco, in favour of 802.1X, and as the VMPS technology is Cisco proprietary, the VLAN assignment can now be carried out in the 802.1X framework. Client switches query the VMPS server using the VLAN Query Protocol, or VQP. Only Cisco produces hardware with VMPS client functionality, and is currently fully supported across their IOS switching lines. Cisco officially only supports the use of Catalyst 4000, 5000 and 6500 switch platforms (with appropriate firmware) as VMPS servers, but these have limited functionality, and only support a static text file transferred into them using tftp. vmps helps with the dynamic allocation of vlan across the network.
