STA (Spanning Tree Algorithm)
The Spanning Tree Algorithm can be used to detect and disable
network loops, and to provide backup links between switches, bridges
or routers. This allows the switch to interact with other bridging
devices (that is, STA-compliant switch, bridge or router) in your
network to ensure that only one route exists between any two
stations on the network. For a more detailed description of how to
use this algorithm, refer to “Spanning Tree Algorithm” on page 4-2.
Spanning Tree Information
The Spanning Tree Information screen displays a summary of the
STA information for the overall bridge or for a specific port. To make
any changes to the parameters for the Spanning Tree, use the STA
Configuration and STA Port Configuration screens.
Spanning Tree
The parameters shown in the following figure and table describe the
current bridge STA Information.
Parameter Description
Spanning Tree State Shows if the switch is enabled to participate in an
STA-compliant network.
Bridge ID A unique identifier for this bridge, consisting of bridge
priority plus MAC address (where the address is
normally taken from Port 1).
Max Age The maximum time (in seconds) a device can wait
without receiving a configuration message before
attempting to reconfigure.
Hello Time The time interval (in seconds) at which the root device
transmits a configuration message.
