Chapter 5 Loading Boot ROM and Host Software

Switch software loading through serial ports in the past is time consuming and cannot
be operated remotely. To address these problems, TFTP and FTP are used to allow
software and file downloading through Ethernet ports. The following subsections
describe how to load software and files in these two approaches.

5.1 Introduction to Loading Approaches

To load software remotely, use FTP or TFTP.
To load software at the local, use XModem at the Console port or TFTP/FTP at an
Ethernet port.
Note:
Ensure that the Boot ROM and host software versions that you download can work with
each other.

5.2.1 Introduction to File Attribute

In Boot ROM, application files, configuration files, and Web files support three kinds of
attributes: main, backup, and none, which are described in Table 5-1.
