IRF devices, with backup devices constantly restarting

NULL

After the customer reported that the two devices were stacked normally, a test was conducted to disconnect the stacking line, and then the stacking line was reconnected. It was found that the slot2 device kept restarting.

Confirmed that there are no issues with performing IRF operations and all steps are correct. The hardware modes of both devices are also the same and have been restarted to take effect.

system-working-mode standard 

hardware-resource switch-mode 0 

hardware-resource routing-mode ipv6-64 

hardware-resource vxlan l2gw 

password-recovery enable

Upon rechecking the configuration, it was found that:

Master device: 

irf mac-address persistent timer 

irf auto-update enable 

irf link-delay 0 

irf member 1 priority 32

backup device:

irf mac-address persistent timer 

irf auto-update enable 

undo irf link-delay //Default is 4S 

irf member 2 priority 1

After modifying the configuration on both ends to be consistent, the normal IRF was successful. After confirmation, the customer modified the irf link delay configuration after the first IRF, but disconnected the stacking line without saving the configuration, resulting in inconsistency between the backup device configuration and the host.
