Which of the following statements best describes the output of the command: show xc 1?
A.
OCH trail name, ITU channel, administrative/operational states, protection states, and Wave Keys for both directions.
B.
A list of cross-connections, including A-end, Z-end, frequency, ID number, OCH trail name, and administrative/operational states.
C.
A list of boards that this cross-connection passes through on the local node, along with administrative/operational states, expected power levels, and measured power levels.
D.
A list of all boards on all nodes that this cross-connection passes through, along with expected power levels, measured power levels, and allowed power deviations.
The command show xc 1 displays a list of cross-connections, including A-end, Z-end, frequency, ID number, OCH trail name, and administrative/operational states. A cross-connection is a logical connection between two ports on an optical network element that allows the transmission of an optical signal from one port to another. The command can be used to view the configuration and status of the cross-connections on a node or a network. The other options are incorrect because they either describe a different command or provide incorrect information.
