Vlans should be tagged on switch to switch links.

Untagged will determine the dhcp address you get back from the server.

Tagged is also good for your elrp vlan. We tend to run a vlan called No_loop on tagged on all ports and use it for our elrp config.

End user devices will need to be on an untagged vlan to get to the internet.

I think you also need to 'untag' the native vlan (not default vlan) on any trunk ports.

Using a "native VLAN" on a trunk means not tagging this VLAN. This is not needed for Extreme EOS nor ExtremeXOS. I would recommend to tag every VLAN on any inter-switch-link. Note that some special configurations (e.g. RSTP on EXOS) do require a native VLAN, but those situations can usually be avoided (e.g. using MSTP instead of RSTP).

this is what I actually do:

Tagged = T = trunk for VLAN
Untagged = U = untrunk = switchport for VLAN
