3: Customize the System Configuration
DC 900-1333P 107
If you are using dual Ethernet or dual fast Ethernet with the
elt, fei, or dc type of
interface, and you anticipate switching between the primary and secondary Ether-
net interface for your boot device while still connecting to the other interface, you
may enter just
elt,[1, 2, or 3], fei, or dc for the added_interface_type parameter. Free-
way will interpret this as an instruction to attach to the first unused interface of
the
elt, fei, or dc type.
So, if you booted from the primary
fei device, for instance, and enter fei for the
added_interface_type, the secondary interface will be attached as the added inter-
face. Likewise, if you booted from the secondary
fei device by entering fei1 for the
boot device and left
fei as the added_interface_type, the primary fei device would be
attached as the added interface.
This eliminates the need to modify the boot configuration file every time you
switch between the primary or secondary interface as the boot device. Note that
you may also explicitly indicate the primary interface by entering
elt0,[1, 2, or 3],
fei0 or dc0 if desired for clarity.
The
added_interface_type parameter may be repeated along with the
added_interface_mask and added_interface_addr parameters to indicate multiple
added interfaces.
Added Interface Mask For each
added_interface_type parameter, the optional
added_interface_mask parameter may be used to specify the subnet mask to be set
for the interface. The parameter must be provided in hexadecimal format. If this
parameter is omitted for an added interface, the subnet mask specified in the
FREEWAY Subnet Mask parameter of the System Boot Parameters menu
(described in Section 4.5.1 on page 153) is used for that interface.
Added Interface Address The
added_interface_addr parameter must be supplied with
each
added_interface_type to indicate the Internet address in decimal format to be
assigned to the added interface.
