MAC address masquerading will only affect objects that are in the according traffic-group, in your example above "traffic-group-1". Your non-floating interface IPs should belong to the "local-only" traffic group and thus be not affected when changing this setting. The masqued MAC address for the floating objects that belong to traffic-group-1 (floating self IPs, virtual addresses, SNAT addresses and so on) will be the same for all objects though (no incrementing). But that is also the case without MAC masquerading. The only difference is that the used MAC address will no longer differ between both cluster members when using MAC masquerading.
