某局点交换机堆叠线断开测试后，再堆叠时备机不停重启

现场开局，客户反馈两台设备正常堆叠起来之后，做断开堆叠线测试，然后再接上堆叠线，发现slot2设备不断重启。

display hardware-resource查看两个设备的硬件资源一致，堆叠配置没有异常，irf-port-configuration active重新激活IRF断开配置故障依旧。

Slot1在堆叠备设备重启过程中无异常信息：

再次核对两个设备配置，发现部分配置不一致，按理来讲堆叠成功后备机会同步主机配置，分裂后两个设备配置应该一致。

设备A：

#

irf mac-address persistent timer

irf auto-update enable

irf link-delay 0

irf member 1 priority 30

#

#

interface Bridge-Aggregation13

description dT:cunchu:JXGCLXY-1F-C-09-SEV-ZXR5300G4X-02U17.Bond0

port access vlan 2110

link-aggregation mode dynamic

stp edged-port

stp port bpdu-protection enable

#

设备B

#

irf mac-address persistent timer

irf auto-update enable

undo irf link-delay

irf member 2 priority 20

#

#

interface Bridge-Aggregation13

description dT:cunchu:JXGCLXY-1F-C-09-SEV-ZXR5300G4X-02U17.Bond0

port link-type trunk

undo port trunk permit vlan 1

port trunk permit vlan 2110

link-aggregation mode dynamic

stp edged-port

stp port bpdu-protection enable

#

将两端配置修改成一致后，正常堆叠成功。

后经确认客户第一次堆叠起来之后修改了irf link-delay配置，但没有保存配置就断开堆叠线，造成备机配置与主机不一致。
