Traditionally, the loading of switch software is accomplished through a serial port.
This approach is slow, inconvenient, and cannot be used for remote loading. To
resolve these problems, the TFTP and FTP modules are introduced into the switch.
With these modules, you can load/download software/files conveniently to the
switch through an Ethernet port.
This chapter introduces how to load BootROM and host software to a switch
locally and how to do this remotely.
