Rapid Super Ring
The checkbox is for you to enable the Rapid Super Ring. Enable this and then configure
Priority and Hello Time for Ring Master selecting. Select Ring Ports (for both Rapid Super
Ring or Super Ring) and Version.
Ring Master (R.M.)
In Rapid Super Ring environment, you should have one Ring Master. The ring master has
the rights to negotiate and decide the forwarding port and blocking port of the ring. One of
the ring ports will become blocking port to prevent data loop from happening. When
detecting a topology change, the ring master will automatically change the blocking port to
forwarding so that the traffic transmitting will not be terminated.
Not like JetNet 4000/4500 series, there is no additional DIP switch to enable R.M. in JetNet
5008G-P. The Ring Master of JetNet 5008G-P is automatically selected by the RSR engine.
The parameter
Priority
is provided to change the Ring Master if need.
Priority:
The switch with highest priority (lowest value) will be automatically selected as
the Ring Master. Then one of the ring ports in this switch will become Forwarding, the other
become Blocking port. If all of the switches have the same priority, the switch with the
lowest MAC address will be selected as the Ring Master.
