Chapter 14 Spanning Tree Protocol The following table describes the labels in this screen. Table 65 Advanced Application > Spanning Tree Protocol > Status: RSTP LABEL Configuration Bridge Bridge ID DESCRIPTION Click Configuration to specify which STP mode you want to activate. Click RSTP to edit RSTP settings on the Switch. 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. The root bridge determines Hello Time, Max Age and Forwarding Delay. Max Age (second) Forwarding Delay (second) 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). Cost to Bridge Port ID Topology Changed Times Time Since Last Change 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. 14.6 Configure Multiple Rapid Spanning Tree Protocol To configure MRSTP, click MRSTP in the Advanced Application > Spanning Tree Protocol screen. See Section 14.1 on page 160 for more information on MRSTP. Figure 101 Advanced Application > Spanning Tree Protocol > MRSTP 168 VES1724-56 User's Guide
