Definition statements

Table 1 lists the changes to SNA definition statements.

For complete information about all changed and new definition statements, refer to z/OS V2R1.0 Communications Server: SNA Resource Definition Reference.

Table 1. Summary of new and changed Communications Server definition statements
Definition statement	Release	Description of update	Reason for change
GROUP	V2R1	In an Enterprise Extender (EE) XCA major node (MEDIUM=HPRIP), the IPADDR parameter is changed to accept an IPv6 address or an IPv4 address.	Enterprise Extender IPv6 address configuration
	V2R1	In a switched major node, the HPREEARB parameter is accepted on the GROUP definition statement. HPREEARB accepts a value of HPRARB or a value of PROGRESS for EE connections.	Simplified Configuration for Progressive Mode ARB
	V1R12	In an Enterprise Extender XCA major node (MEDIUM=HPRIP), a new keyword EEVERIFY is available. It affects the Enterprise Extender connections associated with the connection network defined by this GROUP. EEVERIFY specifies whether VTAM should automatically send an LDLC probe to the remote partner to determine if all ports are accessible during the activation of the EE connection. It also specifies the time interval at which VTAM should send the probe on active EE connections.	Enterprise Extender connection health verification
PATH	V2R1	In a switched major node for an EE connection, the IPADDR parameter is changed to accept either an IPv6 address or an IPv4 address.	Enterprise Extender IPv6 address configuration
PU	V2R1	In a switched major node, the HPREEARB parameter is accepted on the PU definition statement. HPREEARB accepts a value of HPRARB or a value of PROGRESS for EE connections.	Simplified Configuration for Progressive Mode ARB
PU	V1R12	A new keyword EEVERIFY is available on the model major node for Enterprise Extender (DYNTYPE=EE), and on the switched major node. It affects the EE connections with these Enterprise Extender physical units. EEVERIFY specifies whether VTAM should automatically send an LDLC probe to the remote partner to determine if all ports are accessible during the activation of the EE connection. It also specifies the time interval at which VTAM should send the probe on active EE connections.	Enterprise Extender connection health verification
