How to Build a Network That Someone Else Can Support
A network should not require its original installer forever.
Use understandable structure
Consistent naming, organized cabling and sensible device placement make the environment easier to understand.
Document the important information
Record providers, equipment, IP ranges, wireless networks, important services and unusual configuration decisions.
Avoid unnecessary complexity
Every special rule and extra device becomes another thing someone has to understand.
Keep credentials managed appropriately
Important administrative access should be controlled and documented according to the organization's security requirements.
Design for the future
People change jobs, vendors change and equipment reaches end of life. A supportable network assumes someone else may eventually need to work on it.
Supportability is part of good network design.
