In case is you are using Automap then floating IP is prefered over non-floating. However you may get confused some time. Let say you have egress vlan toward pool members and you do not have any floating self-ip, only non-floating on that vlan. You have another vlan with floating self-ip configured. So, when packet leaves the 1st vlan towards pool members, the source IP will be floating IP address of the 2d vlan.

 

Because of that we recommend to configure floating IPs for all vlans or do not configure floating IPs at all (depend on your needs) if the box is not part of HA. In this case you will get rid of that confusion.
