In ACX5448, only one (1) Tag Protocol Identifier (TPID) is supported.
Configuration for the TPID:

Model: acx5448 Junos: 19.3R2.9 JUNOS OS Kernel 64-bit [20191120.0ebd4bf_builder_stable_11] JUNOS OS libs [20191120.0ebd4bf_builder_stable_11] JUNOS OS runtime [20191120.0ebd4bf_builder_stable_11] JUNOS OS time zone information [20191120.0ebd4bf_builder_stable_11]
This behavior is expected. As the above configuration error suggests, this is a limitation with the ACX5448 device.
