STP DIAMETER modifyes stp timers in the switch to optimize convergence time
depending in the size of the SPT DOMAIN.(size of the STP DOMAIN is the
number of hops "switches" connected one to the other).
By default the STP timers in every switch are designed to operate well in a
domain with 7 HOP switches. (7 hops away from the point of view of the root
switch).
Now for example if your domain consist of 3 switches (from the point of view
of the root switch), you can modifiy the diameter to 3, to optimize the stp
bpdu convergence time.
By modifying the diameter, the ios automatically adjusts the hello time,
forward delay time and aging time that best fit in a network size of 3
switches.
So the purpose of the tool is to OPTIMIZE the stp convgernece time.
