IBM: TCP/IP APARs for VM

z/VM TCP/IP APARs (by Release Level)

The following tables list TCP/IP APARs by release level, along with pertinent PTF numbers and RSU inclusive status — an applicable RSU level, No, or N/A (Not Applicable). TLS/SSL applicability also is indicated.

Because RSU content for a given release level is cumulative, an APAR fix listed for a lower level will be included on any subsequent higher-level RSU.
APAR numbers for important or significant APARs are highlighted with red text.
Pre-requisite, Co-requisite and Supersede PTFs are not listed in the tables that follow
