Step 2: Identifying the TCP/IP Processes and
Subnets
Step 2: Identifying the TCP/IP Processes and Subnets
During SWAN concentrator configuration, you must specify the correct TCP/IP process
and subnets for each LAN adapter port used to connect the SWAN concentrator to
your Integrity NonStop NS-series or NonStop S-series server. Each LIF on a LAN
adapter is associated with one subnet on one TCP/IP process.
The TCP/IP process that supports the connection through Ethernet port A is called the
preferred process; the TCP/IP process that supports the connection through Ethernet
port B is called the alternate process. The preferred and alternate TCP/IP processes
must be on different subnets.
Use the TCP/IP subsystem SCF INFO SUBNET and INFO ROUTE commands to
display the TCP/IP process associated with each LIF and associated routers, as shown
in Example 4-4. LIF names are displayed in the Devicename field. For example, LIF
L11123A uses SUBNET #SN1 on the TCP/IP process named $ZTC0 and LIF L11123B
uses SUBNET #SN1 on the TCP/IP process named $ZTC1. (These values are shown
in boldface type.)

and NonStop TCP/IPv6 on page 2-6.
