Fit/Fat Switching Overview

Fit/Fat Switching Overview

A fit/fat switching is implemented by loading the system software file of the fat AP or fit AP.

Loading the system software file on an AP

An AP has a different file system from those on other network devices and a small storage space. The AP must load the system software file online from a file server for an upgrade, but cannot download the system software file in the format of .bin to the storage device on the AP.

An AP can implement fit/fat switching by loading the system software file from a TFTP, an FTP, or SFTP server, as shown in Figure 3-34.

Figure 3-34  Fit/Fat switching networking

The administrator uses a console cable to connect the PC to the console interface of the device and connect GE0/0/0 of the device to the server. The administrator then configures fit/fat switching on the AP. The AP loads the system software file online from the server through GE0/0/0 to complete the fit/fat switching.

The AP6510DN and AP6610DN offer an internal console port, which is used only for maintenance. The console port login is as secure as STelnet/Telnet login. To avoid water intrusion, you are not advised to log in to the AP using the internal console port. STelnet/Telnet or web login are recommended.

Version Restrictions

APs support fat AP from V200R003 and do not support cross-version fit/fat switching. For example, a V200R002 fit AP must be upgraded to a V200R003 fit AP and then switched to a fat AP. A fat AP must be switched to a V200R003 fit AP and then rolled back to a V200R002 fit AP.

  • In V200R006 and later versions, the AP3010DN-AGN, AP5010SN-GN, AP5010DN-AGN, AP6010SN-GN, AP6010DN-AGN, AP6510DN-AGN, AP6510DN-AGN-US, AP6610DN-AGN, AP6610DN-AGN-US, and AP7110DN cannot work in Fat AP mode.
  • The upgrade of a device is closely related to the released software versions. The corresponding upgrade guide is released with each new version and you can upgrade the device according to the guide. To obtain the upgrade guides, visit Huawei technical support website and download the upgrade guide based on the product name and version.

  • For details about device upgrade commands, see Upgrade Commands.
