Figure 4.1: Process for readily managed devices.
This process is fairly complex and relies on the fact that a tool--a network configuration
management solution, to be specific--will handle much of the work. The first part of the process,
Review and Risk Analysis, probably occurs outside the tool. The next part, Change
Development, can probably occur within the tool--the right tool will include configuration
templates and a workflow engine that enforces the process itself.
During change deployment, the tool can automatically ensure that the existing configuration is
backed up and that the change is deployed on schedule. Administrators can be notified that the
change has occurred, allowing them to follow up and check the results of the change. If there's a
problem, the change can be rolled back and effectively undone; if the change is okay, it can be
documented and backed up.
