Parameters
time: Sets the hello time (in 0.01 seconds), ranging from 100 to 1000 in increments of 100 (as indicated
by 100, 200, 300).
Usage guidelines
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 recommends not setting 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.
Examples
# In MSTP mode, set the hello time to 4 seconds.
<Sysname> system-view
[Sysname] stp timer hello 400
