Network Documentation Best Practices: What to Create & Why
Everybody agrees network documentation is extremely important, but there tends not to be a lot of agreement on what that documentation should include. The short answer is that it should include everything that’s relevant—but what that means varies between networks. For example, in a really small network with one switch and a firewall, and perhaps a single wireless access point, there isn’t much to document. It might be enough to put everything in a single diagram.
