Mesh on wan on vlan

[albialbi]

How can I do Mesh on vlan port on wan port?
Following does not work, what is wrong?
uci set gluon.iface_wan_vlan9=interface
uci set gluon.iface_wan_vlan9.name='eth0.9'
uci add_list gluon.iface_wan_vlan9.role='mesh'
uci commit gluon
gluon-reconfigure
reboot

Please post the full config output. You need to remove the pseudointerface from the default roleset if eth0 is enslaved in there.
