现象:
在配置完router 后，将配置文件写入NVRAM的时候报错:
ddn_ks#
*Mar 1 01:33:35.027: NV: Invalid Pointer value(8149EF84) in private configuration structure
*Mar 1 01:33:35.043: NV: Invalid Pointer value(8149EF84) in private configuration structure
*Mar 1 01:33:35.043: %SYS-4-NV_BLOCK_INITFAIL: Unable to initialize the geometry of nvram
% Unknown command or computer name, or unable to find computer address

查阅文档:

后先erase NVRAM，然后再将配置文件写入NVRAM
该问题一般是在升级ISO后出现
