EX3300 - Sub Interface (New to Junos)

I'm new to JUNOS and trying to understand sub-interfaces; what I'm trying to source is how to use ge-0/1/3 as a trunk port for VLAN 24 & 25 traffice while adding a Sub-Interface IP address to VLAN 25 to manage the device.  Unlike Cisco, I'm finding this not so easy with the unit 0 family ethernet-switching.

interfaces {
interface-range Mail {
member-range ge-0/0/0 to ge-0/0/12;
unit 0 {
family ethernet-switching {
vlan {
members Mail;
}
}
}
}
interface-range MGT {
member-range ge-0/0/13 to ge-0/0/23;
unit 0 {
family ethernet-switching {
vlan {
members IMP;

 ge-0/1/3 {
unit 0 {
family ethernet-switching {
port-mode trunk;
vlan {
members [ Mail IMP ];
}
}
}
}
xe-0/1/3 {
unit 0 {
family ethernet-switching {
port-mode trunk;
vlan {
members [ Mail MGT ];
 

vlans {
MGT {
vlan-id 24;
}
Mail {
vlan-id 25;
}
default {
l3-interface vlan.0;
