I have some Juniper switches (Model: ex4550-32f) connected together with trunk ports.
I want to allow VLAN 6 on all below interfaces because it is the main switch and connected to other switches in other locations with one connection only. Why it is blocked on some interfaces? How can I solve it?
You can see the results below:
