[SRX] Dual CPE cluster formation



Article ID: KB36464 KB Last Updated: 14 Feb 2021Version: 1.0

This article highlights the commands we need to run before running cluster enable commands in Node0 and Node1 of SRX 320 Dual CPE (Both PoE and Non PoE models).


In SRX 320 Dual CPE, ge-0/0/0 will act as management physical port after cluster formation. ge-0/0/1 is control port of dual CPE and fabric link can be any ethernet port ge-0/0/3 to ge-0/0/7.

Due to DHCP config present on ge-0/0/0 and switching config (VLANn related config) present on ge-0/0/1 and fabric link port, secondary node will go into "Secondary-hold" state.

Go to Edit mode of SRX 320 nodes and run the following commands before running cluster enable commands to overcome this issue.
