+   * - ``rs.printSecondaryReplicationInfo()``
+
+     - Returns the status of the secondary members of the replica set. This 
+       is identical to the ``db.printSecondaryReplicationInfo()`` method. 
+       The server :method:`rs.printSlaveReplicationInfo()` method is referred 
+       to as ``rs.printSecondaryReplicationInfo()`` in ``mongosh``.
+
+       The following is an example output from the 
+       ``rs.printSecondaryReplicationInfo()`` method issued on a replica set with two secondary members:

+
+   * - :method:`db.getReplicationInfo()`
+
+     - Returns the status of the replica set from the oplog data.
+
+   * - ``rs.isMaster()``
+
+     - Returns the replica set configuration, role, and status for 
+       the ``mongod`` instance that ``mongosh`` is connected to. The ``mongosh`` ``rs.isMaster()`` method is identical to the server :manual:`isMaster </reference/command/isMaster/>` command.
+
+   * - :method:`rs.printReplicationInfo()`
+
+     - Returns the oplog of the replica set member that ``mongosh`` is 
+       connected to. This is identical to the 
+       :method:`db.printReplicationInfo()` method.
+
+   * - :method:`db.printReplicationInfo()`
+
+     - Returns the oplog of the replica set member that ``mongosh`` is 
+       connected to. This is identical to the 
+       :method:`rs.printReplicationInfo()` method.
+
+   * - :method:`rs.status()`
+
+     - Returns the status of the replica set member that ``mongosh`` is 
+       connected to.
