Supervisor的"show module"命令无法识别MSFC/MSFC 2
如果因为Cisco IOS软件镜像被破坏、没有正确安装bootflash或者出于一些原因使得MSFC或者MSFC2进入ROMmon状态，则MSFC/ MSFC 2可能在"show modele"命令输出中消失。下面的输出就是一个例子：
Cat6500 (enable) show module
Mod Slot Ports Module-Type Model Sub Status
--- ---- ----- ------------------------- ------------------- --- --------
1 1 2 1000BaseX Supervisor WS-X6K-SUP1A-2GE yes ok
Mod Module-Name Serial-Num
--- -------------------- -----------
1 SAD040200B3
Cat6500 (enable) session 15
Module 15 is not installed.
下面的例子是MSFC处于其它状态时"show module"命令的输出：
Cat6500 (enable) show module
Mod Slot Ports Module-Type Model Sub Status
--- ---- ----- ------------------------- ------------------- --- --------
1 1 2 1000BaseX Supervisor WS-X6K-SUP1A-2GE yes ok
15 1 1 Multilayer Switch Feature WS-F6K-MSFC no other
Cat6500 (enable) session 15
Trying Router-15...
