Eudemon 200E V300R001. Customer was unable to connect on console line, nor VTY line via telnet because he forget the password. We need to find a way to recover device management.
Handling process is summarized on 4 steps:
1. Restart the device
2. When "Press Ctrl+B to Enter Boot Menu...." is displayed press Ctrl+B and enter password O&m15213 to access the BootROM main menu.
3. Access the main menu or press Ctrl+Z and select the sequence number corresponding to Recover Console Password.
Other version may have Skip Console0 Password option which has the same function as Recover Console Password.
Because CLI is not available we need to connect on bootrom for recovery.
As suggestion, after you log in again on management CLI, configure password for console line.
The following uses user name admin and password huawei as an example:
[Eudemon] user-interface console 0
[Eudemon-ui-console0] authentication-mode local user admin password cipher huawei
