Point-to-Point Network Interface Links The Point-to-Point Network Interface Links screen (#119) in figure 6-8 is displayed when you press the [Go To LINK] function key at the Point-to-Point Network Interface Config screen (figure 6-3). It is also displayed when you type the path name: @NETXPORT.NI.NIname.LINK in the Command window of any screen and press the [Enter] key, where NIname is a configured point-to-point NI.Figure 6-8. Point-to-Point Network Interface Links * To define a new NI link configuration, specify the link name and link type; then press the [Add] function key. The path for the selected link name is added to the configuration file, and the data screen on the path is displayed. Up to 40 network links are supported per Router NI. * To modify an existing NI link configuration, specify the link name; then press the [Modify] function key. The data screen on the path for the specified link is displayed. * To change the link name of an existing NI link configuration, specify the link name and a new name; then press the [Rename] function key. The previously configured name is replaced, and the screen displays the new name in a display field under the label Configured Network Links. * To delete an existing NI link configuration, specify the link name; then press the [Delete] function key. Press the [Delete] function key again to confirm the deletion. The previously configured name is deleted and is no longer displayed in a display field under the label Configured Network Links. Fields Link name Enter the same link name that you entered in the Link Configuration: LAP-B Link Data screen (figure 3-4) for this node. This enables network transport to associate the correct link with this point-to-point NI. The link name is used by network transport when establishing connections. The name can contain as many as eight alphanumeric characters, and the first character must be alphabetic. Related screens: * LINK.linkname The link name of type LAP-B specified in this screen for this node must match the link name in this Point-to-Point Network Interface Link screen. * NETXPORT.NI.NIname.MAPPING.mapentry This screen specifies which link to use to reach a specific node on the point-to-point network. The link specified must be one entered on the current screen. Type Enter DD, for "direct dial," if this is a dial link that provides a connection to a single remote system over a phone line. For direct dial links, the phone number dialed by the local node to reach the remote node never changes. Enter SD, for "shared dial," if this is a dial link that provides connection to more than one remote system. Such a link is said to be shared by more than one remote node, though the connection may only be to one remote node at a time. If you choose shared dial, no other nodes can be accessed through the remote host; it is an end point in the connection. Enter DC, for "direct connect," if this is a non-switched point-to-point link (a private line, leased line, or hardwired connection). Related screen: * NETXPORT.NI.NIname.MAPPING.mapentry This screen allows up to 1024 mappings of point-to-point links to destination nodes. If multiple destinations are mapped to a single link, the link must be configured as a shared dial (SD) link in the current screen. New name (Required only when renaming an existing point-to-point link.) Enter a link name. This new link name is used in place of the current link name for an existing link configuration. Remember, the link name must be the same as the link name configured in the Link Configuration: LAP-B Link Data screen. The name can contain as many as eight alphanumeric characters, and the first character must be alphabetic.
