Creating an Ethernet Subnet
1. Issue the SCF INFO SUBNET $ZZTCP.*, DETAIL command.
2. Identify all TCP6SAM processes that are listed in the LNP field of the SUBNET
display and make a note of these process names.
3. Issue the SCF LISTDEV TCPIP command.
4. Use your list of TCP6SAM names to eliminate the LNP-assigned TCP6SAM
processes. The remaining TCP6SAM process(es) is associated with the default
LNP. This process has access only to the SUBNETs in the default partition.
For example, we know from the LISTDEV command shown in Example 8-3 on
page 8-12 that $ZSAM1 is the only TCP6SAM process associated with an LNP so
$ZSAM2, shown in Example 8-4 on page 8-13, is the TCP6SAM for the default
partition.
Creating an Ethernet Subnet
If an Ethernet SUBNET does not already exist, you can create one using the SCF ADD
SUBNET command. The SCF ADD SUBNET command shown in this example defines
an Ethernet SUBNET named SN1 for NonStop TCP/IPv6 in IPv4 mode or the
TCP/IP/PL environment. The DEVICENAME modifier specifies the name of the logical
interface (LIF) that is used to communicate with the physical interface (PIF) on an
E4SA connected to the system.
-> ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, &
DEVICENAME $ZZLAN.LAN02, IPADDRESS 123.45.67.89,&
SUBNETMASK %HFFFFFF00
After the SUBNET is defined, it must be started using the SCF START SUBNET
command. The SCF START SUBNET command shown in this example starts the
SUBNET named SN1:
-> START SUBNET $ZZTCP.*.SN1
For more information on creating SUBNETs in the NonStop TCP/IPv6 environment,
see the TCP/IPv6 Configuration and Management Manual.
Note. You must also perform this step on the destination system before you can define the
local Expand-over-IP line-handler process. The destination IP address must be specified when
the local Expand-over-IP line-handler process is defined.
