i have switch 2960 and i made port 15 as trunk port. Encapsulation is dot1q. I have configured VLANs 10,20,30 on switch and of course there is VLAN 1 - nativ.
If im right in this trunked port ( 15 ), traffic is tagged for VLAN 10,20,30 and traffic for VLAN1 is untagged.
Is possible to tagg traffic for VLAN1 (nativ, default) and how?
