SRX300 Cluster - Change node IPs

  • 1.  SRX300 Cluster - Change node IPs

    Posted 10-18-2017 04:09

    Hi there, 


    We have 2 SRX300 firewalls in a cluster which are working fine. However, a recent reqirement has come where we need to change the IP of the firewalls. Therefore, if we change the node IPs, on the cluster, would it:


    1) Distroy the cluster?

    2) Require a reboot? 


    We are doing this remotely at an office which is in use. But wanted to check if this would cause any major issues before planning it in.


    Any help would be much appreciated.

    changing the nodes IP's (fxp0) should neither break the CLuster, nor require a reboot as far as i know.

    If you want to be sure, change everything and do a "commit confirmed" - this way, you are back after 5mins in case something goes wrong (wrong subnet etc.)

    Changing IP address wont break cluster and it dont need a reboot.


    Since you are connecting to device remotely, make sure you are not changing IP on which you are connecting, you will lose access.You will eventually be able to connect to new IP once the commit is complete.


    Or you may chnage IP on each node seperately.
