Guidelines
When configuring the hello-time, the max-age setting must be greater than the hello-time setting.
The following relationship should be kept:
2*(forward-delay - 1)>=max-age>=2*(hello-time + 1)
Examples To configure spanning-tree bridge hello time to 5 seconds:
switch(conf-stp)#hello-time 5
