vlan without ip address

[Alexander Lunev]

first of all, you should name and number you vlan same, if it's clan10
on the one side, then it's vlan10 on the other side and in betweeen.
then (though you have to do it first of all), you should understand
how vlan's work, and after that connect ports to each other according
to your scheme.
