Parameter
centiseconds: Specifies the maximum age in centiseconds, ranging from 600 to 4000.
By default, the value is 2000 centiseconds.
Description
Using stp timer max-age command, you can configure the Max Age of the switch.
Using undo stp timer max-age command, you can restore the default Max Age.
Maximum age is used for judging if an RSTP packet is outdated. If the value is set too
small, the spanning tree will be computed too frequently because the network
congestion may be considered as link failure. However, if the value is set too large, the
link failure may not be discovered in time. Maximum age is related to the network
diameter. You can use this command to modify the maximum age in accordance with
the real cases. The default value, 2000, is recommended.
For the related commands, see stp timer forward-delay, stp timer hello.
Example
# Set the Max Age of the switch to 1000 centiseconds.
[Quidway] stp timer max-age 1000
