Introduction to SNAplus2
SNAplus2 Components
NOTE
This guide uses the term TN3270 for information that applies equally to
the TN3270, TN3287, and TN3270E protocols.
SNAplus2 TN server provides access to 3270 host computers for TN3270
users on other computers. TN server enables TN3270 users to share a
host connection with SNAplus2 or with other TN3270 users, instead of
requiring a direct link. TN server also enables TN3270 users to access
hosts that are not running TCP/IP.
The SNAplus2 TN server function is shown in Figure 2-8, “TN Server.”

TN server provides an association between a TN3270 user and a 3270
LU on the SNAplus2 server. All data from the TN3270 user is routed to
the LU. This means that the configuration for both the host and the
TN3270 user is as though they were connected directly; neither needs to
be aware that data is being routed through TN server.
