well here's the topology:-

SW1 <---> SW2

the trunks are on port 19,20 and we are using dot1q with MST. Vlans
1,2,3 are configured on both of them.
Now I want interface 19 to carry vlans 1,2 and interface 20 to carry vlan 3.

So my question is again do i need to configure the spanning-tree mst 1
port-priority on both the switches or just one will work.

thanks
