Description

This command is to be sent to the slave DataHub in a mirroring relationship. It tells the slave all the information it needs about its connection to the master DataHub. This command corresponds to the entries in the Tunnel Master dialog that opens when you click the Add button in the Tunnel/Mirror option of the Properties window.

The DataHub uses mirroring to do tunnelling, so the term 'mirror' is used to name the command.
