I want help for setting up a vlan between two canopy sm’s

Hi I have a client who wants a vlan connection.
So the point is here, he have an canopy Motorola AP and two SM?s, the point is that i don?t know anything about this wireless devices.
I have looked at Motorola product page and support but as I was trying to set up the vlan I have lost the first time the connection and the second the management console from the public air interface.
So if anyone knows how to set up this connection between the sm?s from the beginning i will be grateful.

SM————–>AP<--------------SM Vlan Vlan
