Importance: Low
Is there a way to change the STP diameter from default 7 to say 3 ? I
came accross this question in one of the practice labs & the answer
was something with changing max-age (15 from default 20) & forward
delay. (17 from default 20)
Can some one pass me a link or explain how to derive it. ?
Searched around Group Study & Goolge could not find. Attached link
shows there is a command called "dia" for cat switches. Not sure for
IOS based switches.
