Configuring the operating mode for a 10-GE interface
Introduction to the operating modes
A ten-GigabitEthernet (10-GE) interface operates in LAN or WAN mode:
•
In LAN mode, the 10-GE interface transmits Ethernet packets, providing access to an Ethernet
network.
•
In WAN mode, the 10-GE interface transmits synchronous digital hierarchy (SDH) packets,
providing access to an SDH network. In this mode, the interface supports only point-to-point
connections.
NOTE:
A 10-GE interface operating in WAN mode cannot communicate with a 10G POS interface. Both kinds
of interfaces encapsulate packets as SDH frames, but the SDH frames have incompatible formats.
Introduction to the J0 and J1 overhead bytes
SDH frames have diversified overhead bytes, which perform the operation and maintenance functions
such as hierarchical management of the transport network. J0 and J1 are used to provide internetworking
support between different countries, regions, or network devices of different manufacturers.
The regenerator section trace byte J0 is usually set to a section access point identifier. The sending end
stays connected with the receiving end by sending this byte.
The path trace byte J1, usually set to a high-order path access point identifier, functions in a similar to
keep the connection with the receiving end of the path.
To ensure smooth communication, the J0 and J1 bytes should be matched at the sending and receiving
ends.
