Hi,
I tried latest Openwrt release r13601-d93da0d016 and converting swconfig configuration to DSA.
I have problems with DSA configuration.

I have problem with communication between untagged and tagged interfaces ( lan1.201 and lan3 ) in bridge vlan201 .
This is tcpdump on openwrt when pinging something connected on lan1.201 from PC connected to lan3 .

- DSA setup 2 (router is not booting)
This setup is based on setup provided by dengqf6 in PR2942.
The difference from DSA setup 1 is that there is only one bridge.
I tried configuration based on that setup, but the router is dead (bricked) after reboot.
I don't have serial cable to see where is the problem.
I saw that there is setup in /etc/hotplug.d/iface/21-lan file (not in /etc/rc.local ).
Ports lan1 and lan2 are trunk ports (with vlans 201 , 202 , and 203 ), and ports lan3 and lan4 are untagged ports with vlan 201.
I can boot the previous partition with old swconfig configuration.
# vi /etc/config/network
config interface 'lan'
option type 'bridge'
option ifname 'lan1 lan2 lan3 lan4'
option proto 'none'
config interface 'vlan201'
option ifname '@lan.201'
option proto 'static'
option ipaddr '10.254.201.1'
option netmask '255.255.255.0'
config interface 'vlan202'
option ifname '@lan.202'
option proto 'static'
option ipaddr '10.254.202.1'
option netmask '255.255.255.0'
config interface 'vlan204'
option ifname '@lan.204'
option proto 'static'
option ipaddr '10.254.204.1'
option netmask '255.255.255.0'

# clear out vlan 1

bridge v del dev br-lan self vid 1
# set vlans lan1
bridge v add dev lan1 vid 201
bridge v add dev lan1 vid 202
bridge v add dev lan1 vid 204
# set vlans lan2
bridge v add dev lan2 vid 201
bridge v add dev lan2 vid 202
bridge v add dev lan2 vid 204
# set vlans lan1
bridge v add dev lan3 vid 201 pvid untagged
# set vlans lan2
bridge v add dev lan4 vid 201 pvid untagged
# set vlans cpu port
bridge v add dev br-lan self vid 201 pvid untagged
bridge v add dev br-lan self vid 202
bridge v add dev br-lan self vid 204
I hope somebody can find / locate the problem.
I am not sure where is is the problem, and is configuration in file /etc/hotplug.d/iface/21-lan correct, or it should go also in /etc/rc.local.
Best regards!
