Select a TCP6SAM Process
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 the following 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's a conventional NonStop TCP/IP
process whereas a program name of TCP6SAM means it's a NonStop TCP/IPv6
process. Example 8-3 shows a sample result of the SCF LISTDEV TCPIP command.
In the above example, the processes $ZSAM1 and $ZSAM2 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 TCP6SAM process. As shown in the
Example 8-5 on page 8-14, 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 the
following steps:
1. Issue the SCF INFO SUBNET $ZZTCP.*, DETAIL command.
