Point-to-Point Dial Link Configuration

Dial link configuration provides the information necessary to interface the point-to-point NI to a dial link. The Point-to-Point Dial Link Configuration screen (#104), shown in Figure 6-10 “Point-to-Point Dial Link Configuration Screen”, is displayed when you select an NI link name and link type DD or link type SD at the Point-to-Point Network Interface Links screen (Figure 6-8 “Point-to-Point Network Interface Links Screen”) and press the [Add] or [Modify] function key. It is also displayed when you type the path name:

@NETXPORT.NI.NIname.LINK.linkname

in the Command window of any screen and press the [Enter] key, where NIname is a configured point-to-point NI, and linkname is a configured point-to-point NI link.

Press the [Save Data] function key to transfer the data displayed on the screen to the configuration file you are creating or updating. Verify that the data record has been created by checking that the Data flag is set to Y.

Fields

Enable dial ID protocol (Y/N)

(HP modifiable.) A Y (Yes) value activates the dial ID protocol for a dial link.The dial ID protocol verifies the identity of a remote node and ensures that both local and remote nodes have the required security access.

The dial ID protocol should be disabled (by entering a NO value) only to connect a dial link to a remote node that does not support the dial ID protocol (that is, a non-HP node).

Related screens:

NETXPORT.NI.NIname.LINK
Configures a link name and link type. The link name specified leads to this screen.
NETXPORT.NI.NIname.PROTOCOL.DIAL.SECURITY
Configures security strings for this node.
NETXPORT.NI.NIname.MAPPING.mapentry
Configures information about reachable point-to-point nodes. Remote nodes' security strings are configured on this screen.

Default value: Y

Range: Y or N

Start device on network initialization (Y/N)

A Y (Yes) value means that the device is to begin startup when a NETCONTROL START command is issued for this network interface. The physical layer is activated when NETCONTROL START is issued, but the data link layer of the first remote device is not activated until the first REMOTE HELLO using that device is issued. An N (No) means that a NETCONTROL ADDLINK command must be used to start the device. For more information on these commands, refer to the NS 3000/iX Operations and Maintenance Manual.

Default value: Y

Range: Y or N

Enable idle device timer (Y/N)

This field specifies whether the device is to be disconnected automatically if no packets have been received or transmitted over the link during a specified time period. It is relevant only if a timeout value has been entered in the point-to-point NI screen (see "Related screens").

Related screen:

NETXPORT.NI.NIname
Configures point-to-point network interface information. The value for idle device timeout is configured on this screen.

Default value: Y

Range: Y or N

Disconnect the link with the DSline Close command (Y/N)

A Y (Yes) value means that NS will immediately disconnect the dial phone line when the last user enters a DSLINE nodename;CLOSE command. NS keeps track of the number of times the DSLINE nodename command is issued by all users on the system. When the DSLINE nodename;CLOSE command has been issued this same number of times, NS checks to see if the dial line to the remote node is still connected and if there are any TCP connections still using the line. If the line is connected and there are no TCP connections, NS disconnects the line.

An N (No) value means that the dial phone line will remain connected until the idle device timer expires.

Default value: N

Range: Y or N
