Use undo irf member stack enable to disable multimember stacking capability for an IRF member 
device. 
Syntax 
irf member member-id stack enable 
undo irf member member-id stack enable 
Default 
Multimember stacking capability is enabled for an IRF member device. 
Views 
System view 
Predefined user roles 
network-admin 
Parameters 
member-id: Specifies an IRF member device by its member ID. 
Usage guidelines 
If multimember stacking capability is disabled for a device, the device cannot join an IRF fabric that 
contains other devices. 
You can use the undo form of this command to remove a member device from an IRF fabric for 
troubleshooting or maintenance purposes. The removed member device still runs the original IRF 
settings. However, it does not send or receive IRF control packets. 
After you finish the troubleshooting or maintenance tasks, you can log in to the removed device and 
execute this command to add the device back to the IRF fabric. For this command to take effect, you 
must save the command setting and reboot the device. 
Examples 
# Remove member device 2 from the IRF fabric. 
<Sysname> system-view 
[Sysname] undo irf member 2 stack enable 
Member 2 will leave from the IRF and cannot form an IRF with any other devices. Continue? 
[Y/N]: y 
Operation succeeded. Please check the configuration on member 2 with the IRF for 
configuration collisions. 
# Add the removed device back to the IRF fabric. 
<Sysname> system-view 
[Sysname] irf member 2 stack enable 
Please save the configuration, and then reboot the device for the configuration to take 
effect.
