rapid transition. This is one of the major elements which allows RSTP to achieve faster
convergence times than STP.
Click the folder Rapid Spanning Tree from the Switch Management menu and then three
options within this folder will be displayed as follows.
1. RSTP Switch Settings: Set up system priority, max Age, hello time, etc.
2. RSTP Aggregated Port Settings: Set up aggregation, path cost, priority, edge, etc.
3. RSTP Physical Port Settings: Set up physical, ability and edge status of port.
4.4.4.1 RSTP Switch Settings
Click the option RSTP Switch Settings from the Rapid Spanning Tree menu and then the
following screen page appears.
System Priority: Each interface is associated with a port (number) in the STP code. And,
each switch has a relative priority and cost that is used to decide what the shortest path is to
forward a packet. The lowest cost path is always used unless the other path is down. If you
have multiple bridges and interfaces then you may need to adjust the priorities to achieve
optimized performance.
The Managed Switch with the lowest priority will be selected as the root bridge. The root
bridge is the “central” bridge in the spanning tree.
Hello Time: Periodically, a hello packet is sent out by the Root Bridge and the Designated
Bridges that are used to communicate information about the topology throughout the entire
Bridged Local Area Network.
