Examples # In MSTP mode, set the forward delay timer to 20 seconds. system-view [Sysname] stp timer forward-delay 2000 stp timer hello Syntax stp timer hello time View undo stp timer hello System view Default level 2: System level Parameters time: Sets the hello time in 0.01 seconds, in the range of 100 to 1000 in increments of 100 (as in 100, 200, 300). Description Use stp timer hello to set the hello time of the device. Use undo stp timer hello to restore the default. By default, the hello time is 2 seconds. Hello time is the time interval at which spanning tree devices send configuration BPDUs to maintain spanning tree. If a device fails to receive configuration BPDUs within the set period of time, a new spanning tree calculation process will be triggered due to timeout. HP does not recommend that you set the hello time with this command. Instead, you can specify the network diameter of the switched network by using the stp bridge-diameter command and let spanning tree protocols automatically calculate optimal settings of the hello timer. If the network diameter uses the default value, the hello timer also uses the default value. Related commands: stp timer forward-delay, stp timer max-age, and stp bridge-diameter.
