Make a stack plan
1. Set stack member ID of switch A to 1 and stack member ID of switch B to 2. (Member ID renumber defaults to 1)
2. Plan that switch A serves as the active switch and has the highest stacking priority (150). Switch B has the highest stacking priority (100 by default).
3. Set the stack Domain ID to 10, which does not conflict with that of other stack systems on the network.
4. Switch A and SWITCH B are planned to use ports 10GE3/0/34 to 10GE3/0/37 and 10GE4/0/34 to 10GE4/0/37 for stacking connections. It is recommended that cross-board cables be connected to prevent single board faults.
5. Connect the two switches after they are configured
Configuring switches
Switch A configuration:
stack
stack member 1 priority 150
stack member 1 domain 10
stack link-type linecard-direct
quit
Configure the stack priority of SwitchA to 150 and Domain ID to 10.
Linecard-direct is stacked using spUs.
In the case of the main control board, the command is stack link-type mainboard direct
interface stack-port 1
port member-group interface 10ge 3/0/34 to 3/0/37
port member-group interface 10ge 4/0/34 to 4/0/37

Switch B configuration:
Set the stack member ID of SwitchB to 2, priority to 120, and Domain ID to 10.
Because the inherit-config parameter is specified when the stack member ID is changed, the stack configuration of Member 1 is inherited after SwitchB restarts. If inherit-config is not specified, the stack configuration of Member 1 will not be inherited after SwitchB restarts, and member 2 needs to be used to configure the stack again.

Form a stack
1. After the configuration is complete, save the configuration of switch A and switch B, and shut down the switch.
2. Connect four stack cables.
3. Start switch A first, and then switch B (switch with A higher priority).
4. Run the verification command to check whether the stack is normal and save the configuration.
Stack Verification command
display stack configuration
display stack
display stack topology
Dual-master detection configuration
Dual-active detection is recommended for multi-board switches such as Huawei 12800 series to prevent dual-active switches when stacking failures occur.
After the configuration is complete, connect the network cable.
