I want to use one physical interface but different subinterfaces for failover, stateful and firewall (user data) interfaces. Is it possible? How is the config? My devices are ASA 5520, FOS Ver. 7.2(2)19. By now failover and stateful with subinterfaces are configured, but if I want to configure other ones for firewall I get the error message:
ERROR: Interface is in use by failover
INFO: Use failover command to configure interface name
