How do I add APPN Class of Service to my logon mode table?

You can add APPN Class of Service to your user-coded logon mode table in one of three ways:

You can create APPNTOSA and SATOAPPN tables to allow VTAM® to map Class of Service between APPN and subarea networks, without having to change existing logon mode tables.
You can code the APPNCOS operand for each logon mode entry in the table.
You can create new APPNCOS definitions with the same name as the subarea COS.

To create APPNCOS definitions with the same name as the subarea COS, you can copy the default definition for APPN Class of Service that best fits that logon mode and change the name to match the COS operand coded on that logon mode.
