z  As shown in Figure 10-2, access point (AP) serves as the FTP Client. The test.bin program and 
the BootWare program boot.btm are both saved under the aaa directory of the FTP Server. 
z  The IP address of a VLAN interface on AP is 1.1.1.1/24, the IP address of the FTP Server is 
2.2.2.2/24, and FTP Server is reachable. 
z  User can log in to AP through Telnet to perform operations on AP (download the application 
program from FTP Server and remotely upgrade AP through command lines). Ensure that a route 
exists between User and AP.
