Issue Description
there is two NX230 switching modules that need to be stacked, the NX230 switching module software version is S6300 version V200R001C00

One switch is reloading all the time

Handling Process
Example for Configuring a Stack in a Ring Topology

Networking Requirements

As shown in Figure 1, Switch A, Switch B, Switch C, and Switch D form a stack in a ring topology. The stack system is automatically created. Switch A functions as the master switch, whereas Switch B functions as a standby switch. After the active/standby switchover, the MAC address of the stack system is immediately switched. To avoid updating MAC addresses of the stack system frequently and wasting system resources, set the MAC address switchover time of the stack system to 1 minute after the active/standby switchover.
Figure 1 Networking of a stack in a ring topology

Configuration Roadmap

The configuration roadmap is as follows:
Configure the MAC address switchover time of the stack system on the master switch.
Data Preparation

To complete the configuration, you need the following data:
Service interfaces that need to be configured as stack interfaces on the master switch
Member interfaces to be added to the stack interfaces on the master switch
MAC address switchover time of the stack system
Configuration Procedure

Enable the stack interface function on XGE0/0/1 through XGE0/0/4 as stack interfaces on SwitchA.
system view
[SwitchA] stack port interface XGigabitEthernet 0/0/1 to 0/0/4 enable
Member interfaces to be added to the stack interfaces on SwitchA.
[SwitchA] interface stack-port 0/1
[SwitchA-stack-port0/1] port member-group interface XGigabitEthernet 0/0/1
[SwitchA-stack-port0/1] quit
[SwitchA] interface stack-port 0/2
[SwitchA-stack-port0/2] port member-group interface XGigabitEthernet 0/0/2
# Configure the MAC address switchover time of the stack system on Switch A.
system-view
[SwitchA] stack timer mac-address switch-delay 1
# Run the display stack command on Switch A to check basic information about a stack.

Root Cause

The C1 plate Stack port STACK 1 and C2 plate Stack port STACK 2 is connected, C1 plate Stack port STACK 2 and C2 plates Stack port STACK 1 .

 I have an example for you: the two switches, The first Switch port 13 connect The first Switch port 13, The first Switch port 14 connect The first Switch port 14.

The first Switch  configuration:
system view
[NX230]stack port interface XGigabitEthernet 0/0/13 to 0/0/16 enable                     -------- stack port(13/14/15/16)is enable.
[NX230] interface stack-port 0/1
[NX230-stack-port0/1] port member-group interface XGigabitEthernet 0/0/13       -------- add stack port 13 to stack-port 0/1.

[NX230-stack-port0/1] quit
[NX230] interface stack-port 0/2
[NX230-stack-port0/2] port member-group interface XGigabitEthernet 0/0/14         -------- add stack port 14 to stack-port 0/2.


The second Switch  configuration:
system-view
[NX230]stack slot 0 renumber 1                                                 -------- The second Switch must alter  slot ID,such as number 1  (because slot ID of the first Switch is number 0)
[NX230]reboot                                                                               -------- you must reboot the Switch to take effect the  slot ID
system view
[NX230]stack port interface XGigabitEthernet 1/0/13 to 1/0/16 enable                              -------- stack port(13/14/15/16)is enable.
[NX230] interface stack-port 1/1
[NX230-stack-port1/1] port member-group interface XGigabitEthernet 1/0/14                  -------- add stack port 14 to stack-port 1/1.
[NX230-stack-port1/1] quit
[NX230] interface stack-port 1/2
[NX230-stack-port1/2] port member-group interface XGigabitEthernet 1/0/13                   -------- add stack port 13 to stack-port 1/2.
