有些时候，我们在升级WLC的时候，被告知需要升级WLC的FUS，以防止某些漏洞和不必要的情况发生。
1、什么是FUS？
Field Upgrade Software (FUS)，翻译过来，叫“现场升级软件”，这叫起来太别扭了，也不和中文语境，还是不翻译的得好。
简单的说，FUS就是FUS是一种特殊的AES包，可执行各种与系统相关的组件升级。 我们建议您安装FUS映像，以将引导加载程序（bootloader），现场恢复映像（field recovery image），FPGA / MCU和其他固件等组件升级到最新版本。
2、如何判断FUS是什么版本？
如下表中所列出的是FUS 1.9 下，各组件的版本情况：
|
Cisco WLC Platform
|
|
|---|
|
Cisco 2500 Series Wireless LAN Controllers
|
- Field Recovery Image is upgraded from 7.0.112.21 to 7.6.101.1
- Bootloader is upgraded to 1.0.20
- Offline Field Diagnostics is upgraded from 0.9.28 to 0.9.35
|
|
Cisco 5500 Series Wireless LAN Controllers
|
- Field Recovery Image is upgraded from 7.0.112.21 to 7.6.101.1
- Bootloader is upgraded to 1.0.20
- Offline Field Diagnostics is upgraded from 0.9.28 to 0.9.35
- FPGA Revision version is upgraded to 1.7
- Environment Controller (MCU) Image version is upgraded to 1.8
- USB Console Revision version is upgraded to 2.2
|
|
Cisco Wireless Services Module 2 (WiSM2)
|
- Field Recovery Image is upgraded from 7.0.112.21 to 7.6.101.1
- Bootloader is upgraded to 1.0.20
- Offline Field Diagnostics is upgraded from 0.9.28 to 0.9.35
- USB Console Revision version is upgraded to 2.2
Note Due to a software issue, the FPGA does not get upgraded in a Cisco WiSM2 even though the console output indicates that it has been upgraded.
|
|
Cisco Flex 7500 Series Wireless LAN Controllers
|
RAID firmware
|
如下表中所列出的是FUS 2.0 下，各组件的版本情况：
|
Cisco Wireless Controller Platform
|
|
|---|
|
Cisco 2504 Wireless Controllers
|
An upgrade to FUS 2.0 is mandatory if you have PIC 1.0.19 due to CSCuu46671 ; if you do not have PIC 1.0.19, it is mandatory to upgrade to FUS 1.9 or 2.0 before upgrading to AireOS release 8.3.121.0 or above.
- Bootloader Version is upgraded to 1.0.20
Note Verify the bootloader version by entering the command show sysinfo. The output displays the following line only if FUS 2.0 is installed.
Bootloader Version................... 1.0.20
- Cisco WLCs with PIC version older than 1.0.18 will not show PIC update when upgraded to FUS 2.0
|
|
Cisco Flex 7510 Wireless Controllers
|
- Emergency image is upgraded to 8.1.133.7
- Updates RAID firmware to 20.13.1-0200
|
|
Cisco 8510 Wireless Controllers
|
- Emergency image is upgraded to 8.1.133.7
- Updates RAID firmware to 20.13.1-0200
|
注意：2.0版本没有Cisco 5508,5520和8540无线控制器和Cisco WiSM2的更新。
3、关于升级FUS
- FUS被随WLC 6.0版本之后一同安装。
- FUS只能安装一次。
- 在升级FUS的时候，不需要Console接入，但是，最好还是有Console的接入权限以使得查看整个安装进度。
- FUS升级过程会多次重启WLC，整个过程大约需要30分钟。
- 为FLEX7510控制器平台安装FUS后，还会升级RAID固件。在安装过程中，显示的控制台消息会指示RAID固件的升级。但是，无法通过输入命令或查看引导日志来验证RAID固件升级。
- 注意升级过程中，不要让控制器断电，否则会变砖。
升级命令：大致和WLC image升级一样，GUI的就不用介绍了，简单列举一下CLI的命令。
a. transfer download datatype code
b. transfer download serverip serverip
c. transfer download mode { tftp | ftp }
d. transfer download username user <<<选择TFTP不需要使用user/password
e. transfer download password password
f. transfer download filename filename.aes
g. transfer download path /
h. transfer download start
文件名字，如WLC5508的：AIR-CT5500-K9-1-9-0-0-FUS.aes
当文件上传完毕之后，重启WLC。
reset system
