Hello,
My problem is that I don't understand the difference between access vlan mode and trunk vlan mode. Could you please explain it to me or send me a simple course to understand?
Thank you

Hello,
It's not very complicated, the concept of trunk is different at Cisco and HP for example.
At Cisco:
An Access Port has access to a VLAN which means it will only receive packets that are intended for it.
A Trunk port is used to physically connect two switches, switch/router, etc... so that all packets can pass.
Basically, that's what I understood =) (novice).
A good course on VLANs in FRENCH (hallelujah!)

At HP, however, I don't really know, you have to search the net!

If someone helps you, a thank you and a resolved!!

That is indeed the case for Cisco; in access mode, only the configured VLAN will be visible, while in trunk mode, all VLANs will be visible.
Just a little extra information = it is possible to specify the VLAN encapsulation mode (802.1Q or other) to broaden compatibility for exchanges.
There you go.
