4. Disconnect control and fabric links between the devices in the chassis cluster so that nodes running
different Junos OS releases are disconnected. For this, change the control port and fabric port to
erroneous values. Fabric ports must be set to any FPC number and control ports to any non-IOC port.
Issue the following commands:
admin@cluster#delete chassis cluster control-ports
admin@cluster#set chassis cluster control-ports fpc 10 port 0 <<<<<<< non-SPC port
admin@cluster#set chassis cluster control-ports fpc 22 port 0 <<<<<<< non-SPC port
admin@cluster#delete interfaces fab0
admin@cluster#delete interfaces fab1
admin@cluster#set interfaces fab0 fabric-options member-interfaces xe-4/0/5 <<<<<<< non-IOC port
admin@cluster#set interfaces fab1 fabric-options member-interfaces xe-10/0/5<<<<<<< non-IOC port
5. Commit the configuration.
