Chassis Cluster HA Control Link Encryption
Connect the dedicated control ports on node 0 and node 1. Connect the user defined fabricated ports on node 0 and node 1. To configure two chassis in cluster mode, follow the below steps:
Enable chassis cluster mode on both the nodes, see SRX Series Chassis Cluster Configuration Overview.
- After enabling the chassis cluster, in the device 1, configure HA link encryption as
shown in sample configuration below, commit and reboot. Device 1 needs to be configured
with both node0 and node1 HA link encryption configuration before commit and reboot.

One way to achieve this is to power off device 1 at this point.
- After the device 2 is up, configure HA link encryption as shown in sample configuration
below on device 2. Device 2 needs to be configured with both node0 and node1 HA link
encryption configuration. Commit on node1 (device 2), and finally reboot node1 (device
2).

So this timing needs to be taken care by you, else step 3 needs to be redone until enabling HA link encryption on node1 commit goes through.
