解鎖FC Switch 密碼

FC Switch 被上admin 密碼如何解決

1.準備RS-232 Console線

If you can access serial console to get [VxWorks Boot] prompt you could use "m" command to modify the memoty and "g" command to go to the address. I've successfully wrote my own bootloader/patcher (with i960 GNU binutils cross-toolchains) and run VxWorks (Fabric OS) any w/o any password authentication. Unfortunately, it's not universal solution and highly dependent from the bootloader/firmware version...
P.S. Seems there is proprietary "backdoor" to unlock password on ALL Brocade's FC devices. There is interesting string passed and analysed in the firmware. Unfotrunately, it is not known how to use it.
