Redundant Ring
The most common industrial network redundancy is to form a ring or loop. Typically, managed switches are
connected in series and the last switch is connected back to the first one. In such connection, you can
implement Redundant Ring technology.

(Ring ID/Name)
To create a Redundant Ring enter the Ring ID, which has range from 0 to 31. If the name
field is left blank, the name of this ring is automatically named with the Ring ID. The
maximum number of rings is 32.
Note: Once a ring is created, you cannot change it.
Ring Configuration
ID
Once a Ring is created, the Ring ID appears, and cannot be changed. In multiple ring
environments, the traffic can only be forwarded under the same Ring ID. Remember to
check the Ring ID when there are more than one ring in existence.
Name
This field shows the name of the Ring. If it is not entered when creating, it is
automatically named by the rule RingID.
Version
The version of Ring can be changed here, the choices are Rapid Super Ring or Super
Ring.
Device Priority
The switch with highest priority (highest value) is automatically selected as the Ring
Master (RM). When one of the ring ports on this switch becomes a forwarding port and
the other one becomes a blocking port. If all of the switches have the same priority, the
switch with the highest MAC address is selected as the Ring Master.
Ring Port1
In a Rapid Super Ring environment, you should have two Ring ports. Whether this
switch is a Ring Master or not. When configuring Rapid Super Rings, two ports should
be selected to be Ring ports. For a Ring Master,
one of the Ring Ports becomes the
forwarding port and the other one becomes the blocking port.
