GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches The Forward BPDU while STP Disabled field specifies whether spanning tree BPDUs should be forwarded or not while spanning-tree is disabled on the switch. 6. Click APPLY to send the updated configuration to the switch. Configuration changes take place immediately. The following table describes the STP Status information displayed on the screen. Table 14. STP Status information. Field Description Bridge Identifier The bridge identifier for the CST. It is made up using the bridge priority and the base MAC address of the bridge. Time Since Topology Change The time in seconds since the topology of the CST last changed. Topology Change Count The number of times the topology has changed for the CST. Topology Change The value of the topology change parameter for the switch indicating if a topology change is in progress on any port assigned to the CST. The value is either True or False. Designated Root The bridge identifier of the root bridge. It is made up from the bridge priority and the base MAC address of the bridge. Root Path Cost Path cost to the designated root for the CST. Root Port Port to access the Designated Root for the CST. Max Age (secs) Specifies the bridge maximum age for CST. The value must be less than or equal to (2 X bridge forward delay) - 1 and greater than or equal to 2 X (bridge hello time +1). Forward Delay (secs) Derived value of the root port bridge forward delay parameter. Hold Time (secs) Minimum time between transmission of configuration BPDUs. CST Regional Root Priority and base MAC address of the CST regional root. CST Path Cost Path cost to the CST tree regional root. CST Configuration To configure Common Spanning Tree (CST) and Internal Spanning Tree on the switch, use the CST Configuration screen.  To configure CST settings: 1.
