I have an EX2200 switch that I have configured 4 vlans on - 203, 204, 209 and 215. I used the JWeb to configure it since I am not very familiar with the Junos CLI language.
I assigned vlan 209 to port 0, 204 to port 1, 203 to port 2 and 215 to port 3. My trunk port is port 47 and all vlans are get an ip address and can see the network on vlans 203 and 204 with no issue. I cannot get an ip address for vlans 209 and 215. They are all configured the same way.
