SNA Link/iX Node Managers Guide (30291-90507)

Chapter 4 105
SNA Node Startup and Shutdown
Establishing Sessions with the Remote System
manage the LU-LU sessions on the HP e3000.
For a Type 2.1 Node
Session establishment for a T2.1 node is different than establishment
for a T2.0 node in one major way: An independent LU on a T2.1 node
can establish an LU-LU session with a remote system LU without the
need for a corresponding LU-SSCP session. This is possible because an
independent LU sends a BIND request directly to a remote system LU
to establish an independent LU-LU session. The BIND is routed
through the network to the remote system LU by using the remote
system LU’s name and node name.
NOTE At this time, LU 6.2 API/XL is the only SNA service that makes use of
the T2.1 node capabilities.
