Simple question about vlans

Installing and Using OpenWrt

I would like to know what is the difference between

config bridge-vlan
        option device 'br-lan'
        option vlan '1'
        list ports 'lan1'
        list ports 'lan2'
        list ports 'lan3'
        list ports 'lan4'
        list ports 'wan'

and

config bridge-vlan
        option device 'br-lan'
        option vlan '1'
        list ports 'lan1:u'
        list ports 'lan2:u'
        list ports 'lan3:u'
        list ports 'lan4:u'
        list ports 'wan:u'

or

config bridge-vlan
        option device 'br-lan'
        option vlan '1'
        list ports 'lan1:u*'
        list ports 'lan2:u*'
        list ports 'lan3:u*'
        list ports 'lan4:u*'
        list ports 'wan:u*'

I assume none

Thanks for the attention

Yes, they should all have the same effect. Untagged frames on vlan1 for all ports.

Are you sure? From what I understand lan1:u means the egress packets are untagged but the ingress packets are still required to be tagged, as there is no PVID.

Quite sure, if the lan1:u receives a tagged frame it should be discarded.

A thousand thanks
