華三s5500怎麼查看交換機有沒有密碼

1、以下是配置console密碼的參考命令：有沒有配置密碼，可以看下有沒有相關配置

（1）用戶名密碼登錄：

local-user admin
password simple admin
service-type ter
authentication level 15
quit
line console 0
authentication-mode scheme
quit
（2）密碼登錄：

line console 0
authentication-mode password
set authentication password simple admin
user pri level 3
quit

2、交換機現在能登錄命令行嗎？可以的話，reset sa或者reset factory-default清空配置或者恢複出廠，恢複出廠後除了web管理的個別型號外，沒有默認密碼。

3、如果不能登錄命令行了
