Redundant Ring

Redundant Ring
The most common industrial network redundancy is to form a ring or loop. Typically, the 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. The RocketLinx ES7506 can only create a single ring.
Redundant Ring
To create a Redundant Ring enter the Ring ID, which has range from 0 to 31. If the name field is left
New Ring
blank, the name of this ring is automatically named with the Ring ID
Ring Configuration
ID Once a Ring is created, this appears and can not be changed.
This field shows the name of the Ring. If it is not entered when creating, it is automatically named by
Name
the rule RingID.
Version The version of Ring can be changed here, the choices are Rapid Super Ring or Super Ring.
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
Device Priority
blocking port. If all of the switches have the same priority, the switch with the highest MAC address is
selected as the Ring Master.
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.
Ring Port1
For a Ring Master, one of the ring ports becomes the forwarding port and the other one becomes the
blocking port.
Change the Path Cost of Ring Port1, if this switch is the Ring Master of a Ring, then it determines the
Path Cost blocking port. The Port with higher Path Cost in the two ring ports becomes the blocking port, If the
Path Cost is the same, the port with larger port number becomes the blocking port.
Ring Port2 Assign another port for ring connection.
Path Cost Change the Path Cost of Ring Port2.
