Chapter 13 Spanning Tree Protocol The following table describes the labels in this screen. Table 32 Advanced Application > Spanning Tree Protocol > Status: MRSTP LABEL DESCRIPTION Configuration Click Configuration to specify which STP mode you want to activate. Click MRSTP to edit MRSTP settings on the Switch. Tree Select which STP tree configuration you want to view. 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) a switch can wait without receiving a configuration message before attempting to reconfigure. Forwarding This is the time (in seconds) the root switch will wait before changing Delay (second) 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 This is the number of times the spanning tree has been reconfigured. Changed Times Time Since Last This is the time since the spanning tree was last reconfigured.
