You may have a split brain situation where you actually dont have an active sync and network failover happeneing between all 4 devices. Do you have all 4 devices within the same device-group/traffic-group? When you perform an iqdump on each unit, do you see the other 3 units communicating properly? Can you provide a screenshot of the sync page, where the F5 units part of the device groups are listed with their current status -- ie, grey or green balls.

My ultimate goal will be to have only 2 devices in the traffic group for failover as we will be decommisioning 2 of the LTM's later this year.

 

From the image below I would like to ultimately only have the padf5-core1 and padf5-core2 in the traffic group, but currenly all the traffic is on Pad-F5-2.

 

Can you please provide more information on the iqdump?

Thanks,
