Warning: statement ignored: unsupported platform (ex3400-48t) on Juniper Junos

If you’re seeing this problem when you try to create a VLAN;

ge-0/0/20 {

flexible-vlan-tagging;

native-vlan-id 201;

unit 0 {

vlan-id 201;

family ethernet-switching {

interface-mode trunk;

vlan {

members [ 3 5 35 52 201 ];

}

##

## Warning: statement ignored: unsupported platform (ex3400-48t)

##

native-vlan-id 201;

How to Fix?

You need to try without flexible-vlan-tagging
Exemple:

interface ge-1/0/46 {
native-vlan-id xxx;
unit 0 {
family ethernet-switching {
interface-mode trunk;
vlan {
members [ xx xx xx ];
}
}
}
}
