Please read the manual.
We are not your "do my work" guys
switchport trunk native vlan X OR switchport access vlan X = vlan X port default 1/y (define vlan X as untagged)
switchport trunk allowed vlan add X = vlan x 802.1q 1/y (have VLAN x as tagged on that port)
There is no vtp in Alcatel and you must configure all allowed vlans on a trunk by hand (or use MVRP/GVRP - don't ask me i never used it)

So,
Any different in "native vlan" and "access vlan" ??From your example, it seem they are the same !!!
Please advise....

What (in your experience) should be the difference?
There is none.
In Cisco you specify either "mode access" then you have to configure (the only vlan/) the untagged vlan with
"switchpart access vlan X"
If you want a trunk you have to specify the native (untagged) vlan with "switchport trunk native vlan X"
In Alcatel you don't differentiate between a trunk or a access port. if you need a vlan tagged you just tag it to this port (or linkagg)

@devnull i highly doubt that that is correct. he native-vlan is NOT the same as an access vlan. On cisco, i define a native vlan that is different from the default vlan 1, in order to close a security thread in trunking. I am looking for a similar thing here on alcatel. How do you define the native vlan on a trunk? I understand that you have to allow every TAGGED vlan on a trunk, but UNTEGGED traffic would still be forwarded in the default vlan, right? If not, what happens to untagged traffic arriving on a Trunk-Port?

correct - all incomming traffic without a tag will be forwarded to the default vlan. And outgoing traffic in this vlan will be sent untagged.
