Which interfaces can be configured with BFD sessions
In V200R001C00, only Ethernet interfaces support BFD sessions. In V200R001C01 and later versions, the following interfaces support common BFD sessions: -Physical interfaces: Layer 3 Ethernet interfaces, serial interfaces (including synchronous SA interfaces, E1/T1 interfaces, CE1/CT1/PRI interfaces, CE3 interfaces, and CPOS interfaces), POS interfaces, ATM interfaces (including ADSL interfaces, VDSL interfaces, E1-IMA interfaces, and G.SHDSL interfaces). -Logical interfaces: Ethernet sub-interfaces (including Dot1q sub-interfaces and QinQ sub-interfaces), dialer interfaces, VLANIF interfaces, Layer 3 Eth-Trunk interfaces, IP-Trunk interfaces, MP-Group interfaces, MFR interfaces, IMA-group interfaces, serial sub-interfaces, channelized serial sub-interfaces, IMA-group sub-interfaces, POS sub-interfaces, ATM sub-interfaces, MFR sub-interfaces, and Eth-Trunk sub-interfaces (Dot1q sub-interfaces). NOTE: When a physical Ethernet interface consists of multiple sub-interfaces, a BFD session can be established on the physical Ethernet interface or each sub-interface. In V200R001C01 and later versions, the following interfaces support multicast BFD sessions: -Physical interfaces: Layer 2 and Layer 3 Ethernet interfaces -Logical interfaces: Layer 2 Eth-Trunk interfaces and Layer 3 Eth-Trunk interfaces NOTE: -Multicast BFD sessions cannot be established on Layer 2 Ethernet interfaces, Layer 2 Eth-Trunk interfaces, or Layer 3 Eth-Trunk interfaces of AR120&AR150&AR160&AR200 or AR1200's SRUs. -When a physical Ethernet interface consists of multiple sub-interfaces, a BFD session can be established on the physical Ethernet interface or each sub-interface.

Which interfaces support NAT
The following interfaces support NAT: -Physical interfaces Layer 3 Ethernet interface, Layer 3 GE interface, G.SHDSL interface, VDSL interface, PON interface, serial interface, POS interface, asynchronous interface, ATM interface, BRI interface, and cellular interface -Logical interfaces Dialer interface, tunnel interface, Layer 3 Eth-Trunk interface, VE interface, VT interface, MP-group interface, MFR interface, and IMA-Group interface -Sub-interfaces Ethernet sub-interface, Eth-Trunk sub-interface, ATM sub-interface, serial sub-interface, MFR sub-interface, IMA-Group sub-interface, and POS sub-interface

Does an AR support MPLS TE
Support for MPLS TE: - The AR120&AR150&AR160&AR200&AR500&AR510 do not support MPLS TE. - The AR120-S&AR150-S&AR160-S&AR200-S do not support MPLS TE. Other -S models support MPLS TE starting from V200R005C10. - The AR530 and AR550 do not support MPLS TE. - Other models support MPLS TE starting from V200R002C01.
