Diagnosing SNALINK LU0 problems
The TCP/IP host is implemented with the SNALINK LU0 function.
This function allows the use of an SNA backbone to transfer TCP/IP
protocols. A TCP/IP host with SNALINK LU0 can be an originator, destination,
or router for TCP/IP data. To use the SNALINK LU0 function of TCP/IP,
each connected host must have VTAM® and TCP/IP installed. The SNALINK LU0 application runs in its own
address space and is defined as a VTAM application. There are two types of SNALINK implementations:
- SNALINK LU0, which uses VTAM LU0 protocol
- SNALINK LU6.2, which uses VTAM LU6.2 protocol
This topic describes how to diagnose problems with the
SNALINK LU0 function and contains the following sections:
SNALINK LU6.2 diagnosis is discussed in Diagnosing SNALINK LU6.2 problems.
SNALINK LU0 is a very convenient way to connect to TCP/IP hosts using an existing SNA backbone. An IP datagram destined for a remote host that is connected using SNALINK LU0 is passed to the SNALINK LU0 address space by TCP/IP. The data is packaged into an SDLC frame and transmitted to the remote host using SNA LU0 protocol. Two SNALINK LU0 applications can be configured to connect using a single, bidirectional session or with two separate sessions (one dedicated to send data in each direction).
