Servers and Profiles in Separate ENTRY Objects
Servers and Profiles in Separate ENTRY Objects
Another common method of configuring an OSI/AS subsystem is to put the server-
profile information for each layer in the ENTRY object for that layer.
If you want to configure only one server and one profile for each layer, configure the
ENTRY objects as shown in Table 4-4
.
An example of this method is shown in Appendix A, Examples of Configuration
Command Files.
Configuring Loopback Connections
A loopback connection (sometimes called session loopback mode) is an option available
if both ends of the connection (the calling and the called address) are in the same
OSI/AS subsystem. (Different processes within an OSI/AS subsystem can be located on
the same system or on different systems via an Expand network.) In loopback
connections, only TAPS processes operate; in other words, TSP and NSP processes are
not involved.
Figure 4-1
on this page and Figure 4-2 on page 4-25 show how a loopback configuration
differs from a regular, nonloopback network connection between two Compaq systems
in an Expand network.

2. This APPL ENTRY attribute is optional. Include it only if your application requires it.
