EDS-408A/405A Series User’s Manual

Featured Functions

Decide appropriate coupling ports in each switch and link them together. Next, assign one switch (e.g., Switch A) as coupler and set the proper coupling control port with another switch (e.g., Switch B) in the same Turbo Ring, and then connect them.

Consequently, the Coupler switch (e.g., Switch A) will monitor switch B through the coupling control port to decide whether or not the coupling port’s backup path should be recovered.

ATTENTION

The user only needs to enable the Ring Coupling function on one EDS (not on the opposing EDS or an adjacent EDS). The Redundant Port, Coupling Port, and Coupling Control Port must all be assigned to different ports.

NOTE

Ring Coupling and Ring Master do not need to be set up on the same EDS.

 

 

Configuring Turbo Ring

Use the Communication Redundancy page to configure Turbo Ring.

 

Now Active

 

This shows the communication protocol in use: Turbo Ring, RSTP, or none.

 

Master/Slave

 

This field appears only when selected to operate in Turbo Ring mode. It indicates if this EDS is

 

the Master of the Turbo Ring or not.

 

 

NOTE

The user does not need to set the master to use Turbo Ring, only to assign which segment serves

 

as the backup path.

 

The master will be determined automatically if the user does not set a dedicated master for the

 

Turbo Ring.
