I'm trying to trunk ports on my S4048-ON switch and all documentation I can find tells me to use "switchport trunk", but this doesn't seem to be available. The switch is running Software Version: 9.14(2.16)

I only have 1 vlan (VLAN 2) which I need to be seen throughout the network (on all ports) and of course the native vlan 1.

I'm hoping someone can show me an idiots guide on how I will acheive this... Many thanks in advance!
