Note: Deactivate the Spanning Tree protocol for the ports connected to a
HIPER-Ring, Fast HIPER-Ring, or Ring/Network coupling, because
Spanning Tree and Ring Redundancy or Ring/Network coupling affect each
other.
Activate the MRP compatibility in an MRP-Ring if you want to use RSTP and
MRP in combination.
If you combine RSTP with an MRP-Ring, set the bridges in the MRP-Ring to
a better (numerically lower) RSTP bridge priority than those in the connected
RSTP network. Thus you avoid a connection interruption if connections in the
MRP-Ring become inoperable.
These MSTI tabs in the dialog allow you to manage the individual Multiple
Spanning Tree Instances. The tab is named MSTI, followed by the number
of the instance, e.g. “MSTI 2”.
X switch Spanning Tree on or off at the individual ports, configure the ports
for the global MST Instance (CIST), and display information on the port
status,
X set various protection functions at the ports,
X configure the ports for an existing MST Instance (port path costs and port
priority), read information on the port status, and display information for
the selected MSTI.
