How I determine whether I am using legacy device type configuration statements in my TCP/IP profile?

Starting with V2R1, a new migration health check is provided to use with the IBM Health Checker for z/OS function. The new migration health check determines whether you are using legacy device type configuration statements in your TCP/IP profile.

Support for the DEVICE and LINK profile statements for the following TCP/IP legacy device types will be eliminated in a future release of IBM z/OS Communications Server:

• ATM

• CDLC

• CLAW

• HYPERchannel

• SNALINK (LU0 and LU6.2)

• X.25

Because support will be eliminated for the ATM device type, the following associated TCP/IP profile statements will no longer be supported:

• ATMARPSV

• ATMLIS

• ATMPVC

If you are using V2R1, to implement this new health check, install TCP/IP APAR PI12981 (PTF UI16739) and SNA APAR OA44671 (PTF UA73088).

When the TCP/IP stack processes a legacy device type profile statement, it issues message EZZ0717I configstmt STATEMENT ON LINE lineno WILL BE RETIRED IN A FUTURE RELEASE. See this message, and the associated profile processing messages, for information on the profile data set that contains the statements.
