Configuration 2: Startup Files for a Host in a Subnet
Addressing Environment
The specifications for Logical Interface objects, which provide an interface between
TCP/IP and the E4SA adapter, appear in boldface.
This SCFSBNT file differs from that in Example 3-5
. The most obvious change is that
the IP address in the ADD SUBNET command now matches the configuration in
Figure 3-2
. Also, two additional ALTER SUBNET commands in this file alter the
SUBNET mask for each SUBNET added.
The default subnet mask is %HFFFF0000, so you must distinguish the subnet number
from the host number. Since this sample configuration uses Class B addressing, two
octets are left over for the host address. On a Class B network, you usually split the
subnet number from the host number on the third octet boundary. Thus, you have three
octets for the network address and one octet for the host address.
