[solved] Where vlan-ID tagged/untagged

my system:

LeMaker Banana Pi
OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.228.31946-f64b152)
aditional a USB-ethernet-adapter (eth1)

On eth0 is defined eth0.2, eth0.3, eth0.4, eth0.5, eth0.6.
On eth1 works the WAN fine.

my problem:

the system have not switch. Where can I define the vlan-ID and tagged/untagged mode for the eth0.2, … ?

eth0 is untagged
eth0.2 is same port tagged with VLAN ID #2
