GS716Tv2 and GS724Tv3 Software Administration Manual Figure 3-12 Table 3-11. Spanning Tree CST Configuration/Status Fields Field Bridge Priority Bridge Max Age (secs) Bridge Hello Time (secs) Description When switches or bridges are running STP, each is assigned a priority. After exchanging BPDUs, the switch with the lowest priority value becomes the root bridge. Specifies the bridge priority value for the Common and Internal Spanning Tree (CST). The valid range is 0-61440. The bridge priority is a multiple of 4096. If you specify a priority that is not a multiple of 4096, the priority is automatically set to the next lowest priority that is a multiple of 4096. For example, if the priority is attempted to be set to any value between 0 and 4095, it will be set to 0. The default priority is 32768. Specifies the bridge maximum age time for the Common and Internal Spanning Tree (CST), which indicates the amount of time in seconds a bridge waits before implementing a topological change. The valid range is 6-40, and the value must be less than or equal to (2 * Bridge Forward Delay) - 1 and greater than or equal to 2 * (Bridge Hello Time +1). The default value is 20. Specifies the switch Hello time for the Common and Internal Spanning Tree (CST), which indicates the amount of time in seconds a root bridge waits between configuration messages. The value is fixed at 2 seconds. 3-20 v1.0, July 2009 Configuring Switching Information
