How AsyncOS Selects Default IP Interface
AsyncOS selects the default IP interface based on the order in which the IP interfaces appear under
Network > IP Interfaces page or in the
Network > IP Interfaces page or in the
ifconfig
CLI command. The first IP interface in the list that
resides on the subnet in question is used.
If there are multiple IP addresses configured within the same subnet as the default gateway, the IP
address with the lowest number is used. For example, if the following IP addresses are configured within
the same subnet,
