How to stack 2 S5720 switches (V200R003 and Later Versions)

582 0 1 0



NOTE: Stack-port 0/1 of SWA must be connected to Stack-port 0/2 of SWB and Stack-port 0/1 of SWB to Stack-port 0/2 of SWA 

I used Xgigaethernet as an example of stacking port.

Step 1. Create and configure logical stack ports on the switches and physical ports to them. REPEAT PROCESS IN SWB

[SWA]interface stack-port 0/1

[SWA-stack-port0/1]port interface XGigabitethernet 0/0/1 enable


[SWA]interface stack-port 0/2

[SWA-stack-port0/1]port interface XGigabitethernet 0/0/1 enable


Step 2. Configure the Stack ID and priority of Switches to implement the Master-standby relationship. (In this example SWA is the master)

The default priority of a switch is 100 

[SWA]stack slot 0 priority 200

[SWB]stack slot 0 renumber 1 >>>> Change the Stack ID from 0 to 1

Step 3. Save your configuration then TURN OFF both the switches. CONNECT THE STACK CABLES properly then TURN ON SWA and SWB.

Step 4. Verify if stack is successful. The result should be like this.

<SWA>dis stack

Stack mode: Service-port

Stack topology type: Ring

Stack system MAC: XXXX-XXXX-XXXX

MAC switch delay time: 10 min

Stack reserved VLAN: 4093

Slot of the active management port: --

Slot      Role        MAC Address      Priority   Device Type


0         Master      XXXX-XXXX-XXXX   200        S5720-52X-SI-AC

1         Standby     YYYY-YYYY-YYYY  100        S5720-52X-SI-AC
