Table 69 Advanced Application > Spanning Tree Protocol > Status: MSTP LABEL Configuration CST Bridge Bridge ID DESCRIPTION Click Configuration to specify which STP mode you want to activate. Click MSTP to edit MSTP settings on the Switch. This section describes the Common Spanning Tree settings. 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. Hello Time (second) This is the time interval (in seconds) at which the root switch transmits a configuration message. Max Age (second) Forwarding Delay (second) Cost to Bridge Port ID This is the maximum time (in seconds) the 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). 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. 174 VES1724-56 User's Guide
