<Huawei>unzip vrpcfg_cpy.zip vrpcfg_cpy.bat   //  When the file name extension is .zip, decompress the file in .bat format.
Extract sd1:/vrpcfg_cpy.zip to sd1:/vrpcfg_cpy.bat? (y/n)[n]:y

100%  complete
%Decompressed file sd1:/vrpcfg_cpy.zip sd1:/vrpcfg_cpy.bat.

9. Restore the configuration.

[Huawei]board add 0/1 1E1-MFT                                      
                    ^                                                          
Error: Unrecognized command found at ‘^’ position.
[Huawei]execute vrpcfg_cpy.bat
Information: The script file has been executed completely.
NOTE:
If there is failure information about “board add”, it is a normal situation. No action is required.
10. Reset the passwords for logging in through the console port and Telnet, and run the save command to save the passwords. The password for logging in through the console port has been configured in V200R002C01B130 and later versions.
Configuration Notes
  • The management interfaces of different AR models are:
AR151: Ethernet0/0/3
AR160: GigabitEthernet0/0/0
AR207: Ethernet0/0/6
AR1200: GigabitEthernet0/0/0
AR2220: GigabitEthernet0/0/0
AR2240: GigabitEthernet0/0/2
AR3200: GigabitEthernet0/0/2
  • When performing the last two steps, ensure that users on the serial port are kept online.
  • The preceding method cannot be used on the AR1200 of V200R001C00SPC200 or an earlier version. You must delete the configuration file in the BootROM menu and reset the passwords after the system restarts.

Configuring VLAN ID-based QinQ Stacking on Huawei Router

Background
QinQ mitigates VLAN ID shortage and is widely applied when users connect to carrier networks.
When private networks connect to a carrier network through CEs and PEs, run the qinq
stacking command on CE interfaces connected to PEs so that the CE interfaces add the outer VLAN tag allocated by the carrier to user packets. This implementation saves VLAN IDs and allows user packets to be transparently transmitted on the carrier network.
The configuration overview:
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bridge bridge-id
A bridge group is created and the bridge group view is displayed.
Step 3 Run:
quit
Exit from the bridge group view.
Step 4 Run:
interface { ethernet | gigabitethernet }.subinterface-number
The Ethernet sub-interface view is displayed.
NOTE
Sub-interfaces can only be created on Layer 3 Ethernet interfaces. If an interface works in Layer 2 mode and supports switching between Layer 2 and Layer 3 modes, run the undo portswitch command to switch the interface in Layer 3 mode before creating a sub-interface on the interface.
Step 5 Run:
bridge bridge-id
The Ethernet sub-interface is added to the bridge group.
Step 6 Run:
bridge vlan-transmit enable
The interface is enabled to transparently transmit VLAN IDs.
Step 7 Run:
qinq stacking vid low-ce-vid [ to high-ce-vid ] pe-vid pe-vid [ remark-8021p 8021pvalue2]
VLAN ID-based QinQ stacking is configured.
—-End
This configuration works for Huawei router, such as Huawei AR1200, Huawei AR2220, Huawei AR3200, Huawei AR2200
