How do I connect a 3750 with vlans to a 3750 without vlan?

       I suppose the question is in the title. Not a very good idea, but I have to switch a server stack between different networks occasionally. At the moment my client switch has a vlan on the upstream port and my server downstream port does not. Both ends are complaining about vlan mismatch. Can I tidy this up at all.

Put the uplinks into a dot1q trunk.

upstream:

           switchport trunk enc dot

           switchport mode trunk

downstream:

           switchport trunk enc dot

           switchport mode trunk

           switchport trunk allow vlan 200

result is no link, as I expected, what am I missing?

Maybe downstream went into error-disable?

I have error disable off on both switches.

The vlan 200 stuff must come out of the upstream switch and fail to route - no vlan 200 upstream. I need it to go everywhere.

connect switches as access ports

sw1:

           switchport mode access

sw2:

           switchport mode access

           switchport access vlan 200

so all pc in sw2 in vlan 200 will be connected to all pc in sw1 in native vlan 1
