This article provides information on why the 'vlan-tags' option is not available for AE and Reth interfaces.

The VLAN-tags option is available for the physical interface but not for the AE interface. Please refer to the output below:

root@SRX1# set interfaces ge-0/0/0.0 vlan-?         
Possible completions:
 vlan-id       Virtual LAN identifier value for 802.1q VLAN tags (0..4094)
+ vlan-id-list     List of VLAN identifiers
 vlan-id-range    Virtual LAN identifier range of form vid1-vid2
> vlan-tags      IEEE 802.1q tags


root@SRX1# set interfaces ae0.0 vlan-?                 
Possible completions:
 vlan-id       Virtual LAN identifier value for 802.1q VLAN tags (0..4094)
+ vlan-id-list     List of VLAN identifiers
 vlan-id-range    Virtual LAN identifier range of form vid1-vid2

This is expected behavior, as dual tags are not supported on AE and RETH interfaces. For more information, please refer to the following document: Ethernet Port Switching Modes on Security Devices
