VLANs – OpenWRT

[sjose]

I am trying configure VLANs on the Marvell switch so that I can use the LAN port as access ports such that lan0 and lan1 interfaces are on separate VLANs.
With /etc/config/network file as below, I am unable to ping the LAN ports. What could I be missing here? Also what interface should I be running tcpdump on to verify the the packets are getting internally tagged?

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config interface 'wan'
        option proto 'dhcp'
        option ifname 'wan'

config 'switch' 'eth0'
        option 'enable' '1'
        option 'enable_vlan' '1'
        option 'reset' '1'

config 'switch_vlan'
        option 'vlan' '2'
        option 'device' 'eth0'
        option 'ports' '2 5t'

config 'switch_vlan'
        option 'vlan' '3'
        option 'device' 'eth0'
        option 'ports' '1 5t'

config 'switch_port'
        option 'port' '1'
        option 'pvid' '3'

config 'interface' 'lan0'
        option 'ifname' 'eth0.2'
        option 'proto' 'static'
        option 'ipaddr' '192.168.22.1'
        option 'netmask' '255.255.255.0'

config 'interface' 'lan1'
        option 'ifname' 'eth0.3'
        option 'proto' 'static'
        option 'ipaddr' '192.168.24.1'
        option 'netmask' '255.255.255.0'

Hello sjose,

please consult the latest dts for correct physical interface names (ifname):

https://github.com/MarvellEmbeddedProcessors/openwrt-kernel/blob/openwrt_17.02_release/arch/arm64/boot/dts/marvell/armada-3720-community.dts#L138

e.g. try replacing ‘eth0.2’ with ‘lan0’ and ‘eth0.3’ with ‘lan1’.
