DEF_FAIL,
otherwise.
Required Configuration
None.
Notes / Warnings
IP addresses must be configured in host-order.
An interface may be configured with either:
If an interface’s address(es) are dynamically-configured, no statically-configured address(es) may be added until all dynamically-configured address(es) are removed.
The maximum number of IP address(es) configured on any interface is limited to NET_IP_CFG_IF_MAX_NBR_ADDR (see section D-9-1).
Note that on the default interface, the first IP address added will be the default address used for all default communication. See also section C-9-1.
A host may be configured without a gateway address to allow communication only with other hosts on its local network. However, any configured gateway address must be on the same network as the configured host IP address (i.e., the network portion of the configured IP address and the configured gateway addresses must be identical).
