By default, max. packet length supported by interfaces is 1668 bytes. When traffic flo

ws from service access side of PE device to network side, new Ethernet header and two TMPLS labels need to be added for service packets, which may increase the packet length by()bytes. When UNI side receives packets with length over 1642 bytes, packets will be dropped due to the addition of header at NNI side, affecting service performance. Therefore, jumbo frame. forwarding function on all service related interfaces should be enabled.
