Starting Links and Services

You use the NETCONTROL START command to start the network links and the NSCONTROL START command to start the Network Services. You must start at least one link before you can start Network Services.

When you start the first link, the network transport is initiated as well. The network transport is the software responsible for sending data out over the appropriate communications links, receiving incoming data, and routing incoming or outgoing data to the appropriate destinations. It includes the general protocols and the network interfaces.

Start a Network Link

You will need to issue a start command for each network interface (NI) you want to activate. The NET and GATE keywords allow you to specify the NI that you want to start. Use NET with the network interface name associated with the link you want to initiate. Use GATE with the network interface name of the gateway half you want to initiate.

The first NETCONTROL START command you enter will initiate the network transport software, including the configured protocols. You can initiate the network transport by itself by entering the NETCONTROL START command without any keywords, but you will not be able to communicate with any other nodes on the network.

The NETCONTROL START command requires NM capability.

Start a Link

Issue the following command to start an NS link:

NETCONTROL START;NET=NIname

The NIname is the network interface name that you configured through NMMGR. Start other links as required by entering the command using the appropriate NI names.

Start a Host-Based X.25 Link

If your network includes X.25 links and you are using host-based network management, you will need to use the DTCCNTRL command before you issue the NETCONTROL START command for the X.25 NI. DTCCNTRL starts X.25 and PAD support for the DTC/X.25 Network Access card. Issue the following command (System Operator capability required):

DTCCNTRL DTC=dtcname;CARD=cardnumber;FUNC=function

where function is one of the following:

STARTX25: to start X.25 services;
STARTPADSUP: to start PAD support services;
STARTBOTH: to start X.25 and PAD support services.

For more information on starting host-based X.25 links as well as other uses of the DTCCNTRL command, see Configuring and Managing Host-Based X.25 Links.

NOTE: If you are starting an X.25 link for a system using PC-based network management or if you are not starting an X.25 link, you do not need to use the DTCCNTRL command.

Start Network Loopback

You must start the loopback NI if you wish to perform local loopback or to DSLINE to the local node. Enter the following command:

NETCONTROL START;NET=loopbackNIname

where loopbackNIname is the name configured for the loopback NI. LOOP is the default name.

NOTE: If you use guided configuration to create any NI, a loopback network interface, whose NI name is LOOP, is automatically generated.

Start Network Services

You can start all the available Network Services with a single command, or you can start one or more individual services. To start all Network Services enter the following command:

NSCONTROL START

To start one or more of the individual services, enter the command followed by an equal sign and a list of the desired services, separated by commas. For example, to start only Virtual Terminal and Reverse Virtual Terminal for users on remote nodes, enter the following command:

NSCONTROL START=VT,VTR

See Chapter 7 "Commands" for complete details on the use and syntax of NETCONTROL START and NSCONTROL START.
