Hi all,
having 2 or more switches VLANs are automatically distributed/announced among
all switches. I mean if I want VLAN number
7 be present on different switches must I simply associate ports to that VLAN?
Thanks,
Alex.

If you have two switches that both have VLAN 7 on them, then the two
are *different* VLANs unless there is a tagged VLAN 7 trunk path
between the relevant ports.
For example, if ports 1, 2, 21, and 22 are all marked as being in
VLAN 7, and you have bridging (or IRB) set up between ports 1 and 2
(e.g., bridge group 30) and between 21 and 22 (e.g., bridge group 74),
but there is no bridge between the two groups, then they are effectively
-different- VLAN 7s... except when the switch gets them confused
for Spanning Tree or ARP table purposes.
Simply having two switch with ports in VLAN 7 is not enough to integrate
VLAN 7 between the two switches: the trunk that connects the switches
must carry VLAN 7. (If this were not the case, then the VLAN 7 that
I create here would be the same VLAN 7 that you create there.)

Assuming that your current setup
(trunking btw switches )is working for vlan7 on different switches then
Yes you just have to associate the port to vlan 7 .
