Command Request Support

The next three tables list the SNA command requests supported by Host Integration Server 2006. Note that not all commands are supported for every LU-to-LU session type. For example, Bracket Initiation Stopped (BIS) is only supported for use by an APPC LU.

The following three tables categorize requests in the following order:

  1. Session control requests
  2. Function management data requests: network services (maintenance) and network services (session)
  3. Data flow control requests

The three tables denote the category for each request by the setting of the request/response unit (RU) category bits in the request/response header (RH), and by the function of the request. Host Integration Server 2006 does not support commands that fall in the network control request category.

For more information about command requests, see your IBM documentation.
