What If I Forget the Huawei S9700 Password for Console Port Login?

When you forget Huawei S9700 password for logging in through the console port, use either of the following two methods to set a new password.

Logging In to the Device Through STelnet/Telnet to Set a New Password

It is recommended that you use STelnet V2 to log in to the device.

Ensure that you have an STelnet/Telnet account and administrator rights. The following uses the command lines and outputs of logging in to the device using STelnet as an example. After logging in to the device through STelnet, perform the following operations.

# Take password authentication as an example. Set the password to Huawei@123.

<HUAWEI> system-view
[HUAWEI] user-interface console 0
[HUAWEI-ui-console0] authentication-mode password
[HUAWEI-ui-console0] set authentication password cipher Huawei@123
[HUAWEI-ui-console0] return
<HUAWEI> save

# Take AAA authentication as an example. Set the user name and password to admin123 and Huawei@123, respectively.

<HUAWEI> system-view
[HUAWEI] user-interface console 0
[HUAWEI-ui-console0] authentication-mode aaa
[HUAWEI-ui-console0] quit
[HUAWEI] aaa
[HUAWEI-aaa] local-user admin123 password irreversible-cipher Huawei@123
[HUAWEI-aaa] local-user admin123 privilege level 15
[HUAWEI-aaa] local-user admin123 service-type terminal
[HUAWEI-aaa] return
<HUAWEI> save

Clearing the Lost Password Using the BootROM/BootLoad Menu

You can use the BootROM/BootLoad menu of the device to clear the lost password for console port login. After starting Huawei switch, set a new password and save your configuration. Perform the following steps.

1. Connect the terminal to the console port of the device and restart the device. When the following message is displayed, press Ctrl+B and enter the BootROM/BootLoad password to enter the BootROM/BootLoad menu.

   Press Ctrl+B to enter boot menu ...  1 
   
   Password:       //Enter the BootROM password.

2. Select Clear password for console user on the BootROM/BootLoad menu to clear the password for console port login.
3. Select Boot with default mode on the BootROM/BootLoad menu to start the device as prompted.
4. After the device is started, log in through the console port. Authentication is not required when you log in. Set a password as prompted after login.
5. You can set an authentication mode and password for the console user interface according to service requirements.

Huawei S9700 8-Port 40GBASE-X Interface Card (FC, QSFP+) EH1D2L08QFC0

Application

A 40GE network can be established by installing 40GE cards on aggregation switches and core switches (S9700), as shown in Figure 1.

Figure 1 40GE cards deployed on a campus network 

Huawei S9700 supports 40 GE cards EH1D2L02QFC0 and EH1D2L08QFC0. A 40GE network with 40GE cards deployed has the following advantages:

• Provides higher bandwidth.
• Is compatible with 10GE networks because a 40GE interface can be split into four 10GE interfaces. This feature enables customers to seamlessly upgrade their 10GE networks to 40GE networks.
• Has a higher efficiency and lower packet loss ratio than a 40GE network established by bundling four 10GE lines for load balancing.

The 40GE cards are used on networks that need to provide high bandwidth, for example, video surveillance bearer networks and high-definition (HD) video conference bearer networks. The following uses an HD video conference bearer network as an example to describe application of 40GE cards.

Transmission of HD video and voice flows consumes high bandwidth on a network, especially on the aggregation layer and core layer. Aggregation and core devices usually become bottlenecks on an HD video conference bearer network. As shown in Figure 1, 40GE cards are deployed on the aggregation layer and core layer to transmit HD video and voice flows faster, more efficiently, with fewer packets lost. This deployment ensures sufficient bandwidth for the HD video conference bearer network and delivers high quality HD images and voice.
