SNAplus2 Components
SNAplus2 implements an APPN node to communicate with other nodes
on the SNA network. This provides logical unit (LU) 6.2 support for
APPC and CPI-C capabilities and for 5250 emulation, as well as LU 0, 1,
2, and 3 support for 3270, RJE, and LUA communications.
SNAplus2 can operate either as a LEN node or as an APPN end node,
depending on its configuration. Certain functions are supported only on
end nodes, as defined by the APPN architecture. These differences are
indicated where necessary in this manual; where no differences are
indicated, the information applies to both node types.
Figure 1-1, “SNAplus2 Components,” shows the components of SNAplus2
and how they work together.
