pix ios 7.x 에서 6.x 로 downgrade 하는 방법이 따로 있어요.
일반적인 ios upload 명령어로 7.x 버전 ios 가 올라가 있는 상태에서 6.x ios를upload 하면 정상 동작 하지 않습니다.
제경우 moniter mode로 빠졌었던 것 같네요.
Downgrade from PIX 7.x to 6.x -
pixfirewall(config-if)# downgrade tftp://192.168.0.2/pix635.bin
This command will reformat the flash and automatically reboot the system.
