H3C V7版本AP通过V5版本AC降级成V5

开启V5平台AC的capwap功能

[AC]_h
Now you enter a hidden command view for developer's testing, some commands may
affect operation by wrong use, please carefully use it with our engineer's
direction.
[AC-hidecmd]fpl-diag enable//必须先enable
Are you sure you want to enable FPL-DIAG? [Y/N] y
% FPL-DIAG has been enabled.
[AC-hidecmd]fpl-diag drv_capwap_set 1  //  开启capwap 

重启生效

观察AP这边的情况

The Extend BootWare is self-decompressing................................
Done!
System should be degraded to ComwareV5,please waiting.//准备降级v5
............................................................................
............................................................................
............................................................................
.............................................................
Updating Extended BootWare..........Done.//刷新boot
System have been degrated successfully!//降级成功
Rebooting...... 

降级成功之后，再次关闭ac的capwap功能重启生效或者不关闭ac的capwap情况下在ac的wlan ap试图下开启tunnel compliance draft（建议后者）

这个时候AP任然无法上线，需要把AC的lwapp功能开启
[AC-wlan-ap-43]tunnel compliance draft//或者
[AC-hidecmd]fpl-diag enable//必须先enable
Are you sure you want to enable FPL-DIAG? [Y/N] y
% FPL-DIAG has been enabled.
[AC-hidecmd]fpl-diag drv_capwap_set 0  //  关闭capwap
