Configuring mac based vlans on cisco/3550
- Thread starter FWHATER

This isn't possible directly on the switch. You can achieve this though by using VMPS (VLAN Management Policy Server). This requires either a CatOS based switch such as a Catalyst 4000 or 5000 (I don't think this feature was added to the Catalyst 6000 series?). The CatOS switch TFTP copies a file that contains a list of MAC to VLAN entries, the VMPS Client switches query the VMPS Server (the CatOS switch) when a port goes active and it has read the MAC address. The VMPS Client switches put the port in the VLAN it receives from the VMPS Server.
There are also some UNIX VMPS Server applications available (free I think as well).
This is all quite old though now and isn't the way forward. I wouldn't deploy dynamic VLAN's anywhere and the preferred network 'model' is now to constrain your VLAN's instead of spanning them over multiple switches. What are your reasons for wanting a MAC-based VLAN anyway? it is possible alternative solutions will fit better.
You can also use 802.1x to assign VLAN's although this requires your client PC's to have an 802.1x supplicant installed. You would also need a RADIUS Server configured with the appropriate Radius attributes to assign the VLAN.

Thanks for the info. I saw mac-based vlans available on the 6500 series and higher. I guess I just wanted to know if the 3550 had this same capablity. The reason for the mac-based vlan as opposed to port based was to save a trip to the wiring closet in the event of a move. While very tedious, using a mac-based vlan would allow the user to move about freely and still belong to the vlan it was assigned to. It's all experimental. Just testing.
