Anyone knows about this switch Aruba 2530, and how I can make vlans with the nethserver.
Did you try and had some issues?
Which steps did you followed?
Did you read the documentation?
https://docs.nethserver.org/en/v7/base_system.html?highlight=vlan#logical-interfaces
The VLAN config options on the switch are (IMO) a lot more powerful than the options by NethServer.
If you configure your VLAN’s on the switch isn’t that sufficient?
