Ring Coupling for a “Turbo Ring” Ring

To configure the Ring Coupling function for a “Turbo Ring” ring, select two switches (e.g., Switch A and B in the

above figure) in the ring, and another two switches in the adjacent ring (e.g., Switch C and D). Decide which

two ports in each switch are appropriate to be used as coupling ports, and then link them together. Next, assign

one switch (e.g., Switch A) to be the coupler and connect the coupler’s coupling control port with Switch B (for

this example).

The coupler switch (i.e., Switch A) will monitor switch B through the coupling control port to determine whether

or not the coupling port’s backup path should be recovered.

Ring Coupling for a “Turbo Ring V2” Ring

Note that the ring coupling settings for a “Turbo Ring V2” ring are different from a “Turbo Ring” ring. For Turbo

Ring V2, Ring Coupling is enabled by configuring the Coupling Port (Primary) on Switch B, and the Coupling

Port (Backup) on Switch A only. You do not need to set up a coupling control port, so that a “Turbo Ring V2”

ring does not use a coupling control line.

The Coupling Port (Backup) on Switch A is used for the backup path, and connects directly to an extra

network port on Switch C. The Coupling Port (Primary) on Switch B monitors the status of the main path,

and connects directly to an extra network port on Switch D. With ring coupling established, Switch A can

activate the backup path as soon as it detects a problem with the main path.

ATTENTION

Ring Coupling only needs to be enabled on one of the switches serving as the Ring Coupler. The Coupler must

designate different ports as the two Turbo Ring ports and the coupling port.
