attaches to the console or telnets to the router, they view the active configuration on the
terminal. The configuration file can also be transferred to or from a TFTP server.

Figure 3-2 shows the commands that manipulate the configuration file. Each command is
described in Table 3-2. Older commands, such as write terminal , configure terminal , config-
ure memory , write memory , write network , and configure network , are confusing. The
functions of these commands are accomplished with the showing or copying of the startup con-
figuration (startup-config) and the running configuration (running-config). The startup-config
is the configuration in NVRAM. The running-config is the configuration in active memory.
