The Start TCP/IP Interface (STRTCPIFC) command starts a Transmission Control Protocol/Internet Protocol (TCP/IP) interface. The line associated with the interface is varied on, if required.
This command can be used to:
Routes are bound to interfaces using a best match first algorithm. This algorithm is based on the state of the interface and on the type of service (TOS) specified for the route and interface. When starting an interface, routes associated with an inactive interface can move to the interface started provided that interface can be used to reach the next hop gateway of the route for the requested TOS.
Attention: Before attempting to start an X.25 interface, ensure that the remote system information (RSI) for non-DDN X.25 interfaces that use a permanent virtual circuit (PVC) is configured. Use the Add TCP/IP Remote System (ADDTCPRSI) command to do this. Incoming data from a remote system on the X.25 network is not processed unless an RSI entry for the PVC is configured on the X.25 interface before the interface is started.

Specifies the internet address of the interface that had previously been added to the TCP/IP configuration with the Add TCP/IP Interface (ADDTCPIFC) command.
Note: Either the INTNETADR or the ALIASNAME parameter must be specified for the command, but not both of them.
An IPv4 internet address is specified in the form nnn.nnn.nnn.nnn, where nnn is a decimal number ranging from 0 through 255. An internet address is not valid if it has a value of all binary ones or all binary zeros for the network identifier (ID) portion or the host ID portion of the address.
An IPv6 internet address is specified in the form x:x:x:x:x:x:x:x, where x is a hexadecimal number ranging from 0 through X'FFFF'. "::" may be used once in the IPv6 address to indicate one or more groups of 16 bits of zeros. The "::" may be used to compress leading, imbedded, or trailing zeros in the address.
An IPv6 internet address must be a unicast address and must not contain an imbedded IPv4 address (compatibility or mapped). If the IPv6 address is a link-local unicast address, a line description name must be specified for the LIND parameter.
If the internet address is entered from a command line, the address must be enclosed in apostrophes.

Specifies the name of the interface to be started. The alias name specified may be for an IPv4 or IPv6 interface.
Note: Either the INTNETADR or the ALIASNAME parameter must be specified for the command, but not both of them.

Specifies the name of the line description associated with the interface being started.

Example 1: Starting an Interface
STRTCPIFC INTNETADR('9.5.11.125')
This command causes the TCP/IP protocol stack to activate the interface associated with the internet address 9.5.11.125.
Example 2: Starting another Interface
STRTCPIFC INTNETADR('156.93.81.7')
This command causes the TCP/IP protocol stack to activate the interface associated with the internet address 156.93.81.7.
Example 3: Starting AUTOSTART(*YES) Interfaces
STRTCPIFC INTNETADR(*AUTOSTART)
This command causes the TCP/IP protocol stack to activate all interfaces that have the AUTOSTART parameter set to *YES using the Add TCP/IP Interface (ADDTCPIFC) or Change TCP/IP Interface (CHGTCPIFC) commands.
Example 4: Starting an Interface with the Alias Name
STRTCPIFC ALIASNAME(TEST_NETWORK)
This command causes the TCP/IP protocol stack to activate the interface associated with the alias name TEST_NETWORK.
Example 5: Starting an Ethernet IPv6 Interface
STRTCPIFC INTNETADR('1234:5678:9ABC:DEF0:1111:2222:3333:4444')
This command causes the TCP/IP protocol stack to start the IPv6 interface associated with address 1234:5678:9ABC:DEF0:1111:2222:3333:4444.
Example 6: Starting an Ethernet IPv6 Link-Local Interface
STRTCPIFC INTNETADR('FE80::1234') LIND(ETHLINE)
This command causes the TCP/IP protocol stack to start the IPv6 link-local interface associated with address FE80::1234 and line description ETHLINE.
Example 7: Starting IPv6 Stateless Address Auto-Configuration On An Ethernet Line
STRTCPIFC INTNETADR(*IP6SAC) LIND(ETHLINE2)
This command causes the TCP/IP protocol stack to start IPv6 stateless address auto-configuration for line ETHLINE2.
