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.
