4000. By default, the value is 2000 centiseconds.
Description
Use the
stp timer max-age
Use the
undo stp timer 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Maximum age is used for judging if an RSTP packet is outdated.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 a 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", or complexity of the switched network. The default
value, 2000, is recommended.
