ET PORT MASTERING

Use the port set port mastering command to configure port master/slave settings of the currently selected TAP
module. The command sets the port's master/slave relationship with the link partner on a 1G RJ/copper link when
in TAP mode. In effect, it determines which end of the link is responsible for the synchronization clock. The link
will only work if there is one master and one slave.
For example, if port pairing AB are operating in TAP mode, you are advised to force the partner of A to have the
same settings as B, and vice versa, which (in the case of Mastery) is done by setting A to
