Setup with swconfig:

#!/usr/bin/bash


INTERFACE=eth0

# Delete all IP addresses and get link up
ip addr flush dev ${INTERFACE}
ip link set ${INTERFACE} up

# Lamobo R1 aka BPi R1 Routerboard
#
# Speaker | LAN1 | LAN2 | LAN3 | LAN4 || LAN5 | HDMI
# SW-Port |  P2  |  P1  |  P0  |  P4  ||  P3  |
# VLAN    |  11  |  12  |  13  |  14  ||ALL(t)|
#
# Switch-Port P8 - ALL(t) boards internal CPU Port

# Setup switch
swconfig dev ${INTERFACE} set reset 1
swconfig dev ${INTERFACE} set enable_vlan 1
swconfig dev ${INTERFACE} vlan 101 set ports '3 8t'
swconfig dev ${INTERFACE} vlan 102 set ports '4 0 1 2 8t'
swconfig dev ${INTERFACE} set apply 1

How to achieve this setup CURRENTLY with DSA?

And in the future (time plan)?

Thank you.

Ciao,
