1 The outer MAC of the Ethernet packet that encapsulates an MPLS packet
2 Three MPLS labels deep
3 Only applies if there are 3 or fewer MPLS labels when an IP header follows the MPLS header
4 In the standalone-VC mode, the IP traffic packet fields are used for null and dot1q tagged traffic; only source and destination MACs are used for qinq tagged traffic. In the standalone operating mode, source and destination MACs and MPLS label stacks (two labels deep) are used for qinq tagged traffic.
5 Two MPLS labels deep
6 In the standalone-VC operating mode, Ethertype is used only for null and dot1q tagged traffic; it is not used for qinq tagged traffic.
7 Outer MACs inside the payload just after the MPLS header
8 Used when the IP header follows the MPLS header
9 Source and destination IPv6 address
