To configure CST settings:
1.Specify values for CST in the appropriate fields:
•Bridge Priority. 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
•Bridge Max Age (secs). 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
•Bridge Hello Time (secs). 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.
•Bridge Forward Delay (secs). Specifies the switch forward delay time, which indicates the amount of time in seconds a bridge remains in a listening and learning state before forwarding packets. The value must be greater or equal to (Bridge Max Age / 2) + 1. The time range is from 4 seconds to 30 seconds. The default value is 15.
•Spanning Tree Maximum Hops. Specifies the maximum number of bridge hops the information for a particular CST instance can travel before being discarded. The valid range is
