Huawei switch stack configuration

Stack configuration

It's private technology , The stacking technologies of various manufacturers are not compatible , Stacking requires that the member devices stacked must be of the same model ( Same as large version ), Please refer to Huawei's official instructions ：
https://support.huawei.com/enterprise/zh/tool/product/enterprise-network

40.1 There are two types of Huawei stacking
istack For box switches
css Frame switch oriented
40.2 Stack configuration
Sw1(1、2 mouth )------------- Sw2(1、2 mouth )
There are four steps ：1 Member number 2 Configure priorities 3 Configure the stack interconnect 4 Link aggregation
40.2.1 Member number ( member ID)
The default is 0,slot Slot numbers are also members ID Number , Such as g0/0/1 The front of 0 This is the slot , the second 0 Is a daughter card

[sw2]stack slot 0 renumber 1 # Change the slot tag number to 1
Warning: All the configurations related to the slot ID will be lost after the slot ID is modified.
Do not frequently modify the slot ID because it will make the stack split. Continue? [Y/N]:y...
Info: Stack configuration has been changed, and the device needs to restart to make the configuration effective.
<sw2>reboot # After completion, you need to restart
Info: The system is now comparing the configuration, please wait...........................
Warning: The configuration has been modified, and it will be saved to the next startup saved-configuration file . Continue? [Y/N]:y
Now saving the current configuration to the slot 0...........
Save the configuration successfully.
Info: If want to reboot with saving diagnostic information, input 'N' and then execute 'reboot save diagnostic-information'.
System will reboot! Continue?[Y/N]:y

40.2.2 Configure priorities
First out main switch , One master, one standby and many slaves . The default priority is 100, The bigger the number, the better , If the priority is the same, see the motherboard mac,mac The smaller the better. .
Be careful ： The equipment started first acts as the main equipment . It means priority 100 Start first , priority 105 Start after , That priority 100 The first thing to start is the master , No preemption principle .
Manual active / standby switchover is required if preemption is not required , The order is slave switchover ( Huawei 、 Hua three )
[sw1]slave ?
restart Restart slave board
switchover HA switch slave to master

Warning: Do not frequently modify the priority because it will make the stack split. Continue? [Y/N]:y....

40.2.3 Configure the stack interconnect
Create a logical stack port , Must be cross connected

sw1
[sw1]int stack-port 0/? # 0/? Inside 0 yes slot Slot number
<1-2> Port number # Can only be created 2 individual
[sw1]int stack-port 0/1 # Create logical interfaces 0/1
[sw1-stack-port0/1]port int g0/0/1 enable # hold g0/0/1 Place on logical interface 0/1 Inside
Warning: Enabling stack function may cause configuration loss on the interface. Continue? [Y/N]:y
[sw1-stack-port0/1]port int g0/0/2 en # hold g0/0/2 Place on logical interface 0/1 Inside
Warning: Enabling stack function may cause configuration loss on the interface. Continue? [Y/N]:y
Check the configuration
[sw1]dis stack configuration

---------------Configuration on slot 0 Begin---------------
stack enable
stack slot 0 renumber 0
stack slot 0 priority 105
stack reserved-vlan 4093
stack timer mac-address switch-delay 10
interface stack-port 0/1
port interface GigabitEthernet0/0/1 enable
port interface GigabitEthernet0/0/2 enable
interface stack-port 0/2
---------------Configuration on slot 0 End-----------------
sw2
[sw2]int stack-port 1/2 # Create logical interfaces , Cross connect
[sw2-stack-port1/2]port int g1/0/3 to g1/0/4 enable # Multiple... Can be placed at the same time
notes ： Operating time port int g1/0/1 to g1/0/2 enable Tips can't be used , Change it to 3 and 4 This is different from the topology above

When the configuration is complete , The standby device automatically restarts
Check for success
