Important Note:  The above example can be used for configuring the SRX1400, SRX3400, and SRX3600 too, except for the control-ports configuration. The 'set chassis cluster control-ports' commands are not set for these devices:

The SRX1400 automatically uses transit ports ge-0/0/10 and ge-0/0/11 for the control ports 0 and 1 respectively.  See KB20916 - Control ports for Chassis Cluster configuration on SRX1400.
The SRX3400 and SRX3600 uses two designated, labeled ports for the control ports.
