Point-to-Point Mapping Configuration

The Point-to-Point Mapping Configuration screen (#115) in Figure 6-13 “Point-to-Point Mapping Configuration Screen” is displayed when you press the [Go To MAPPING] function key at the Point-to-Point Network Interface Configuration screen (Figure 6-3 “Point-to-Point Network Interface Configuration Screen”). It is also displayed when you type the path name:

@NETXPORT.NI.NIname.MAPPING

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

Figure 6-13 Point-to-Point Mapping Configuration Screen

The screen following this one allows you to configure a set of characteristics for a route from the local node to a remote node.

Mapping is creating a route from this node to any other node in the network. You create routes by first assigning a name to each possible route from this node. Then you create routes to adjacent and remote nodes by identifying the adjacent or remote node's IP address and which link is used to reach the node.

12 router NI's are supported per system, depending on the number of available hardware slots (one NI must be used for loopback). Each router can have up to 1024 mappings. However, 4096 is the absolute maximum number of unique phone numbers supported per NMCONFIG File.

There may be multiple routes to a destination node; if the routes are through different adjacent nodes, a mapping may be configured for each of them. For example, Figure 6-14 “Configured Mapping” shows a point-to-point network that could have eight mappings configured for node A.

Figure 6-14 Configured Mapping

If node A is the node being configured, mappings are needed for routes to both node B and node C, and for routes through nodes B and C to any other node. Mapping could be configured for each of the following routes (the rightmost node in these sets is the destination node):

Routes to adjacent nodes:

A-B: (uses Link 1)
A-C: (uses Link 3)

Routes to non-adjacent nodes through B:

A-B-D: (uses Link 1)
A-B-D-E: (uses Link 1)

Routes to non-adjacent nodes through C:

A-C-D: (uses Link 3)
A-C-E: (uses Link 3)

Alternate routes to adjacent nodes:

A-C-D-B: (uses Link 3)
A-B-D-C: (uses Link 1)

Note that you do not need to configure alternate routes to nodes B and C; however, you can configure the routes listed above (A-C-D-B and A-B-D-C) to provide alternate paths if the link used for the primary route fails.

Use the fields and the function keys of this select screen to perform the desired action, as follows:

To define a new mapping configuration, specify a name for the route (in the route name field) and press the [Add] function key. The path for the selected route is added to the configuration file, and NMMGR displays a mapping data screen (called the Point-to-Point Reachable Nodes screen). This screen must be configured to define the specified route.
To modify an existing mapping configuration, specify the name of the route (route name) and press the [Modify] function key. NMMGR displays the Point-to-Point Reachable Nodes screen with the data corresponding to the specified route name.
To change the name of an existing mapping configuration, specify the existing route name and a new name and press the [Rename] function key. The previously configured name is replaced, and the new name is displayed under the heading "Configured Mappings."
To delete an existing mapping configuration, specify the existing route name and 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 field under the heading "Configured Mappings."

Fields

Route name: Enter a name to represent a route between the node you are configuring and another node on the point-to-point network. This name can contain as many as eight alphanumeric characters; the first character must be alphabetic. To help keep track of routes you can use the destination node name as the route name. If you have more than one route to a given node, you can name the routes nodename1, nodename2, and so forth.
New name: (Required only when renaming a route.)Enter a new route name. This new name is used in place of the current name for an existing route. The name can contain as many as eight alphanumeric characters. The first character must be alphabetic.
