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 you to 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.
Examples
# In MSTP mode, set the hello time to 400 centiseconds.
<Sysname> system-view
[Sysname] stp timer hello 400
stp timer max-age

undo stp timer max-age

Default level
2: System level
Parameters
time: Sets the max age in centiseconds, ranging from 600 to 4000 in steps of 100 (as in 600, 700,
800).
Description
Use the stp timer max-age command to set the max age timer of the device.
Use the undo stp timer max-age command to restore the default.
By default, the max age is 2000 centiseconds.
In the CIST of an MSTP network, the device determines whether a configuration BPDU received on a port
has expired based on the max age timer. If yes, a new spanning tree calculation process starts. The max
age timer is ineffective for MSTIs.
HP does not recommend you to set the max age timer 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 max age timer. If the network diameter uses
the default value, the max age timer also uses the default value.
Related commands: stp timer forward-delay, stp timer hello, and stp bridge-diameter.
Examples
# In MSTP mode, set the max age timer to 1000 centiseconds.
