The tool can also provide another entry point into the process by automatically detecting
changes. The detection of a change can result in an immediate backup and notification, allowing
administrators to ensure that the change was authorized. Unauthorized changes can be readily
rolled back.
This process involves many steps, but most are handled automatically (or made much easier) by
the tool. This process is suitable for devices such as routers, switches, firewalls, and so forth--
devices that lend themselves readily to a network configuration management solution.
Processes for Less Readily Managed Devices
Devices that aren't as readily managed should, in theory, have the same process; after all, it's the
process that is resulting in the benefits of reduced downtime and so forth. However, processes
such as the one that Figure 4.1 illustrates are often too complex for administrators to actually
follow in their daily routines; thus, it is wise to develop a process that is easier to work with
when tools aren't available to handle the hard work. Consider the process in Figure 4.2.
