This is true. But note that flexible-ethernet-services is not the same as
stacked-vlan-tagging or flexible-vlan-tagging.

Afraid you'll be disappointed then. This is from an M7i:
FPC 0 E-FPC
PIC 1 REV 08 750-010238 PB7782 1x G/E SFP, 1000 BASE
Xcvr 0 NON-JNPR PR05014273 SFP-T
ge-0/1/0 {
stacked-vlan-tagging;
encapsulation flexible-ethernet-services;
unit 1 {
vlan-tags outer 2 inner 3;
family inet {
address 10.0.0.1/30;
}
}
}
JunOS lets you configure it - but it doesn't work, and there are a couple
of nasty error message logged:
May 30 14:58:34 xyzzy /kernel: ether_iflconfig:ge-0/1/0 (porttype 57) does not
support vlan-tags outer <vlan-id> inner <vlan-id> option
May 30 14:58:34 xyzzy dcd[4326]: DCD_CONFIG_WRITE_FAILED: Interface ge-0/1/0,
configuration write failed for an IFL ADD: Operation not supported
I'd argue that you shouldn't be allowed to configure this at all, since
it doesn't work.
