Usage Guideline
There are some constraints on the relationship of the three timers. Please refer
to the following formulas:
2 × (Bridge_Forward_Delay - 1.0 seconds) >= Bridge_Max_Age
Bridge_Max_Age >= 2 × (Bridge_Hell 1.0 seconds)
An error message will be returned if the equation is not satisfied.
This configuration will take effect on STP version and RSTP version only.In
MSTP mode, Use the command
spanning-tree mst
(timers)
to configure the
MSTP timers.
