Point-to-Point Mapping Configuration 

The Point-to-Point Mapping Configuration screen (#115) in figure 6-13 is
displayed when you press the [Go To MAPPING] 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.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 

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 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.
