Question for all:

In the SNA hierarchy there are defined types 5,4,2 and 1 nodes.

>From what I've read so far I've assembled the following:

Type 5        IBM Mainframe (Runs VTAM)                             SSCP
& PU5
Type 4        3705/3725/3745/3746 FEP/Communications Controllers    PU4
Type 2        3174 Cluster Controller                               PU2
Type 2        Token Ring SNA Gateway                                PU2
Type 1        Token Ring Device                                     LU
Type 1        TN3270 Terminals                                      SLU

Type 5 & 2    Cisco Router acting as DSPU Concentrator              PU5
& PU2

Is this anywhere near close?

Does an ethernet client running a TN3270 session also appear as an SLU
or LU?

Sorry if this is basic but SNA is the area that I am definately weakest
and while I can configure up basic DLSW+ services I prefer to understand
the underlying principles.
