DESCRIPTION
Click Configuration to specify which STP mode you want to activate. Click MRSTP to
edit MRSTP settings on the Switch.
Select which STP tree configuration you want to view.
Root refers to the base of the spanning tree (the root bridge). Our Bridge is this Switch.
This Switch may also be the root bridge.
This is the unique identifier for this bridge, consisting of bridge priority plus MAC address.
This ID is the same for Root and Our Bridge if the Switch is the root switch.
This is the time interval (in seconds) at which the root switch transmits a configuration
message. The root bridge determines Hello Time, Max Age and Forwarding Delay.
This is the maximum time (in seconds) a switch can wait without receiving a configuration
message before attempting to reconfigure.
This is the time (in seconds) the root switch will wait before changing states (that is,
listening to learning to forwarding).
Note: The listening state does not exist in RSTP.
This is the path cost from the root port on this Switch to the root switch.
This is the priority and number of the port on the Switch through which this Switch must
communicate with the root of the Spanning Tree.
This is the number of times the spanning tree has been reconfigured.
This is the time since the spanning tree was last reconfigured.
