QS.5.2 Configuring the UR Switch for Ring Only Mode

NOTE

By setting STP type to RSTP two choices of the span tree algorithm will be available: the standard RSTP (Rapid Spanning Tree Protocol) or the high speed “Ring Only Mode”

For information about RSTP setup, refer to the User Manual.

This feature can be used only when the Switches are connected to form a single ring topology. This means that only two ports per Switch are used to form the ring; all other ports will not be part of this ring or another ring. RO mode has typical recovery time of ≤ 5 ms/hop.
