https://community.checkpoint.com/t5/General-Topics/Faiover-ports-on-cluster/m-p/239121#M39941 <P>I have two CP15400 devices configured with 4 L3 ports to 4 different zones. Since I no longer need one of the zones, I have removed the physical port but kept the logical configuration intact.<BR />Initially, CP_01 was active and CP_02 was passive. I first removed E1 from CP_02, then removed E1 from CP_01. The active-passive status on both devices remained unchanged.</P><P>In this case, I would like to ask: if I continue to use the two devices without removing E1, and one more port on CP_01 goes down, will failover occur to CP_02? And when that port comes back up, what will the status of the two devices be?</P><P>Thank you so much!</P> Tue, 21 Jan 2025 08:18:53 GMT Sacmaugacon 2025-01-21T08:18:53Z https://community.checkpoint.com/t5/General-Topics/Faiover-ports-on-cluster/m-p/239121#M39941 <P>I have two CP15400 devices configured with 4 L3 ports to 4 different zones.
