ProSafe M5300 Switch 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. • Bridge Hello Time (secs) - Specifies the bridge 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. The value must be less than or equal to (Bridge Max Age / 2) - 1. The default hello time value is 2. • Bridge Forward Delay (secs) - Specifies the bridge 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 1-127. • Spanning Tree Tx Hold Count - Configures the maximum number of bpdus the bridge is allowed to send within the hello time window. The default value is 6. Field Bridge identifier Time since topology change Topology change count Topology change Designated root Root Path Cost Root Port Identifier Max Age(secs) Forward Delay(secs) Hold Time(secs) CST Regional Root CST Path Cost Description The bridge identifier for the CST. It is made up using the bridge priority and the base MAC address of the bridge. The time in seconds since the topology of the CST last changed. Number of times topology has changed for the CST. 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. It takes a value if True or False. The bridge identifier of the root bridge. It is made up from the bridge priority and the base MAC address of the bridge. Path Cost to the Designated Root for the CST. Port to access the Designated Root for the CST. Path Cost to the Designated Root for the CST. Derived value of the Root Port Bridge Forward Delay parameter. Minimum time between transmission of Configuration BPDUs. Priority and base MAC address of the CST Regional Root. Path Cost to the CST tree Regional Root. Configuring Switching Information 147
