Hi sahilsha thanks for your solution, yes hearbeats sent/received are incrementing previously this version was working fine for us but now it is not applying new configuration. We will ugrade its OS can you suggest good KB on how to upgrade JUNOS in cluster safely because these firewalls are in remote location we have only remote management over here. Also please tell how much time will it take to upgrade or how much downtime should we take from our clients.
Thanks
