to or greater than the value for vlan-id1. The value range for the vlan-id argument is 1 to 4094. If you
set the STP, RSTP, or MSTP max age, do not specify this option.
time: Sets the max age in centiseconds in the range of 600 to 4000 in increments of 100 (as in 600,
700, 800).
Usage guidelines
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 the configuration BPDU has expired, a new
spanning tree calculation process starts. The max age timer takes effect only on the CIST (or MSTI
0).
As a best practice, do not 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. This
command makes the spanning tree protocols automatically calculate the optimal settings for the max
age timer. If the network diameter uses the default value, the max age timer also uses the default
value.
Examples
# In MSTP mode, set the max age timer to 1000 centiseconds.
<Sysname> system-view
[Sysname] stp timer max-age 1000
# In PVST mode, set the max age timer for VLAN 2 to 1000 centiseconds.
<Sysname> system-view
[Sysname] stp vlan 2 timer max-age 1000

Use stp timer-factor to configure the timeout period by setting the timeout factor.
Timeout period = timeout factor × 3 × hello time.
Use undo stp timer-factor to restore the default.
