还有设了enable secret ，enable password 就无效了
Cisco ios enable password 和 enable secret 的区别
6C3524_1#enable ?
<0-15> Enable level
<cr>
<0-15> Enable level
<cr>
6C3524_1(config)#enable ?
last-resort Define enable action if no TACACS servers respond
password Assign the privileged level password
secret Assign the privileged level secret
use-tacacs Use TACACS to check enable passwords
6C3524_1(config)#enable password ?
0 Specifies an UNENCRYPTED password will follow
7 Specifies a HIDDEN password will follow
LINE The UNENCRYPTED (cleartext) 'enable' password
level Set exec level password
6C3524_1(config)#enable secret ?
0 Specifies an UNENCRYPTED password will follow
5 Specifies an ENCRYPTED secret will follow
LINE The UNENCRYPTED (cleartext) 'enable' secret
level Set exec level password
//但是注意：在实际操作上enable password 0 passwordstr 和 enable password 7 passwordstr 都会出错的，enable secret也同！所以只要记牢enable password 是不加密的，enable secret 是加密的就够了。还有设了enable secret ，enable password 就无效了。
