Why the 5-4--3 rule?

By benjaminr ·
Is the 5-4-3 rule for signal integrity or collision integrity? Also, will today's switches allow you to exceed the 5-4-3 rule and maintain a viable network (Hybrid-Fast Ethernet & Fiber Optic)?

Why the 5-4--3 rule?

by McKayTech In reply to Why the 5-4--3 rule?

My understanding may not be complete but I have always understood that the purpose of the 5-4-3 rule was to ensure that collisions would be detected properly.

Since a fully switched environment, by definition, has no collision domains, the rule would not seem to apply in that environment.

My opinion is that the 5-4-3 rule has out-lived it's usefulness as a guiding principle for network design.
