pair." If the current port is the fiber port, the output includes "Media type is optical fiber." You can
use the display this command in combo interface view to determine whether the fiber port or
copper port of the combo interface is active. If the combo enable fiber command exists in the output,
the fiber port is active. Otherwise, the copper port is active.
Changing the active port of a combo interface
Step
1. Enter system view.
2. Enter Ethernet interface view.
3. Activate the copper combo
port or fiber combo port.

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, as follows:
LAN mode—In LAN mode, the 10-GE interface transmits Ethernet packets, providing access to an
•
Ethernet network.
WAN mode—In WAN mode, the 10-GE interface transmits SDH packets, providing access to an
•
SDH network. In this mode, the interface supports only point-to-point connections.
A 10-GE interface in WAN mode encapsulates Ethernet packets in SDH frames, and a 10G Packet over
SDH (POS) interface encapsulates PPP packets in SDH frames. However, these two types of interfaces
cannot communicate with each other, because the framing formats used by them are different.
Introduction to J0 and J1 overhead bytes
SDH frames have diversified overhead bytes, which accomplish the operation and maintenance
functions such as hierarchical management of the transmission network.
J0 and J1 are used to provide internetworking support between devices of different countries, regions, or
vendors.
The regenerator section trace byte J0 is usually set to a section access point identifier. The sending end
keeps the connection with the receiving end by sending this byte repeatedly.
The path trace byte J1, a byte in the high-order path overhead and usually set to a high-order path access
point identifier, functions in a similar way to keep the connection with the receiving end of the path.
To ensure smooth communication, the J0 and J1 bytes should be matched at, respectively, the sending
and receiving ends. For more information about SDH and SDH overhead bytes, see relevant technical
documentation.
