Cross-Connect (XC)
This chapter contains the cross-connect configuration examples to connect the two cross connection ports. 
The cross connect is bi-directional. The traffic which is received on the first interface is transmitted out to the second interface and the traffic which is received on the second interface is transmitted out to the first interface.
It is point-to-point and same end points (EP) cannot be used for another cross connect.
This following are the types of end points supported by this port based on cross connect.
1.	Native Ethernet interface
2.	LAG interface
