LABEL DESCRIPTION
Configuration Click Configuration to specify which STP mode you want to activate.
Click RSTP to edit RSTP settings on the Switch.
Bridge 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.
Bridge ID 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.
Hello Time
(second) 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.
Max Age
(second) This is the maximum time (in seconds) the Switch can wait without
receiving a configuration message before attempting to reconfigure.
Forwarding
Delay (second) 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.
Cost to Bridge This is the path cost from the root port on this Switch to the root
switch.
Port ID 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.
Topology
Changed Times This is the number of times the spanning tree has been reconfigured.
Time Since Last
Change This is the time since the spanning tree was last reconfigured.
