• Ingress-tunnel accounting with exclude-ethernet-overhead:
• The exclude-ethernet-overhead option, lets the user exclude the Ethernet header (14
bytes) and Ethernet overhead (20 bytes) and CRC overhead (4 bytes) when collecting the
byte statistics. In other words, it counts only the size of MPLS packet. The
exclude-ethernet-overhead option does not work with untagged ports carrying q-in-q
packets for IP over MPLS, nor does it count multiple tags in a packet.
NOTE
This feature is applicable only on LSPs for which the devices are an ingress LER.
NOTE
LSP tunnel statistics are not supported when an ingress LER is a two node LSP (PHP), or when traffic
is forwarded to a directly connected Provider Edge Router (PE).
