To enable a profile that uses a static IP address for automatic profile selection, you need to add
ExcludeAuto=no
to the profile. The order in which profiles are tried can be influenced by the Priority= variable. Profiles with the same priority value are tried in alphabetical ordering.
The following is taken from https://bbs.archlinux.org/viewtopic.php?id=192607.
Let me give an explanation. In automatic profile selection, it is the role of netctl to decide not only when to start a profile, but also which profile to start.
For wireless connections netctl looks at the ESSID and signal strength to select a profile. For wired profiles, the best it can do is try profiles that could fail. A dhcp client will time out if no dhcp server is active, hence profiles that use dhcp can fail. The same does not hold for profiles that use static addresses. How could netctl determine which profile to start? It cannot and therefore such profiles are excluded from automatic profile selection by default.
In some cases this is not what you want. One such case is present in this topic, where there is only one static profile for an interface and it makes sense to use it. Another such case is when suitability of a profile can be tested, for example by testing reachability of some server. By adding ExecUpPost="/usr/bin/arping -qf -w 1 -I $Interface 192.168.2.1" to a profile that uses a static address, the profile can fail and is suitable for automatic profile selection. In this case too, it is meaningful to add ExcludeAuto=no to the profile.
