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
