Hello everone, I wonder if VLAN is all insure. for exemplo, I wish add a new VLAN for my DMZ network. but I'm afraid there will be others VLAN traffic on these VLAN DMZ. I think that sometimes the Switch makes broadcast flow traffic to all ports regardless what VLAN the port belong.
I'm mistaken ?? it is possible confirm that every VLAN is independent and never receive any type traffic from others VLANs ??
any tips about traffic forwarding between VLANs is welcome.

VLANs are, by definition, totally separated in traffic.

Hi everyone,
You're right – VLANs are designed to be isolated by default, independent of any other VLANs on the network. This means ports belonging to one VLAN won't normally see traffic from other VLANs. Think of it as creating separate virtual networks within your physical infrastructure.
In your example, adding a new VLAN for your DMZ network will keep its traffic isolated from other VLANs like production or management. The switch shouldn't be flooding broadcast traffic to all ports regardless of their VLAN membership.
