Hi,


You can't do this statically by configuring a port to be a member in more than VLAN, but you can use dynamic VLANs (With the VMPS, you can assign switch ports to VLANs dynamically, based on the source Media Access Control (MAC) address of the device connected to the port):

What kind of access are you looking for ? If it's layer 3 access, you should have a device that routes between these 20 Vlans and any access port on any of the Vlans should be able to access all the remaining Vlans via the L3 device.


If it's layer 2 access, you can purchase a NIC (for the intended devices) that support do1tq trunking and configure the switchport as trunk.


HTH,
