Select a TCP6SAM Process
only TCP6SAM process that has access to the LNP that SUBNET SN116 and its IP
address 172.10.188.140 form. Note also that SN117 shows DEFAULT in the LNP field.
If you want to use the default LNP, select a SUBNET that has DEFAULT in the LNP
field.
Select a TCP6SAM Process
The TCP/IP socket access method (TCP6SAM) is the process that provides access to
the NonStop TCP/IPv6 environment. In configuring Expand-over-IP for this
environment, you use the name of a TCP6SAM process for the ASSOCIATEDEV
modifier in Step 4: Create the Line-Handler Process.
To obtain a list of running TCP6SAM processes, issue this command:
> LISTDEV TCPIP
The SCF LISTDEV command lists all the TCP/IP processes. A program name in the
SCF LISTDEV display of TCPIP means that it is a conventional NonStop TCP/IP
process whereas a program name of TCP6SAM means it is a NonStop TCP/IPv6
process. Example 8-4 shows a sample result of the SCF LISTDEV TCPIP command.
In the above example, all the processes are TCP6SAM processes. In NonStop
TCP/IPv6, if logical network partitioning is not configured, all TCP6SAM processes
have access to all the IP addresses, so you can select any of the TCP6SAM processes
for the Expand line-handler process. However, if logical network partitioning is
configured, the TCP6SAM process you select for the ASSOCIATEDEV modifier must be
listed in the LNP field of the SUBNET you want to use.
In this example, we use $ZSAM1 as our T
CP6SAM process. As shown in the
Example 8-3 on page 8-12, this TCP6SAM process is associated with the IP address
172.10.188.140.
The INFO SUBNET, DETAIL command shows the TCP6SAM processes that are
associated with configured LNPs. If you want to use the default partition in an
LNP-configured NonStop TCP/IPv6 environment, you have to perform several steps
because there is no direct way to determine the TCP6SAM process names for the
default partition. (The TCP6SAM process is not displayed in the INFO SUBNET,
DETAIL command.) To find TCP6SAM processes for the default partition, perform
these steps:
