Defining Connectivity Components
Overview
and they must be configured on the adjacent nodes as
well as on the SNAplus2 node, so you may need to
consult your SNA network planner.
Operating as an APPN Node
If the SNAplus2 node is an end node in an APPN
network, the number of links that you need to
configure can be greatly reduced. You can configure
links to one or more adjacent network nodes and access
all nodes in the APPN network using these links. If you
want to access other adjacent nodes directly, you can
configure links to them too—this is not usually
necessary, but it can give better performance. If the
adjacent nodes are connected by token ring, Ethernet,
or FDDI, direct links can be set up dynamically so you
don't need to configure them—just make sure that you
configure the network as a connection network when
you define the port.
The benefits of APPN networking are always available
for 5250 and independent APPC, but they do not apply
to 3270, RJE,or LUAunless you use DLUR. (DLUR
supports communications between a host and
dependent LUs on the local node or on downstream
nodes in an APPN network.) You can use DLUR only if
your host supports DLUS, so you should consult your
SNA network planner if you are interested in using
DLUR.
Using 3270, RJE, or LUA on Multiple Nodes
If you are going to use 3270, RJE, or LUA on multiple
nodes, you can reduce the number of host links
required by using PU concentration. You can use PU
concentration to connect non-SNAplus2 nodes, or
SNAplus2 nodes in a different domain. If you want to
use PU concentration, you need to configure a host
link, enable PU concentration, and configure links
between the SNAplus2 node and the downstream
systems. Traffic between the host and downstream LUs
can then use links to the PU concentrator instead of
requiring direct links to the host. Unless you already
have links between each downstream node and the
host, you can avoid additional investments in cabling
and link configuration by using PU concentration.
