Connection type:	LAN and ATM LAN emulation	ATM native	Enterprise Extender (HPRIP)
statements:	PORT PU (subarea node)	PORT PU (TGs over PVCs)	PORT PU
dependency:	USER=SNA (LINE statement)	DIAL=NO (TGs over PVCs)
range:	4–252	4–252	4–252

For Enterprise Extender, there must be different SAP values for host connections. In other words, if two hosts are issuing dials, both in and out, they must be using different SAP values to represent the connection. For example, if host 1 issues a dial to host 2 with

local SAP = 04
remote SAP = 08

and the connection comes active, host 2 cannot issue a dial back to host 1 with

local SAP = 08
remote SAP = 04

because the connection represented by the SAP pair 0408 is already active. If host 2 issues the dial with the above information, the dial request will be failed and the operator will receive a sense code of FFC80004.

Note: See z/OS Communications Server: SNA Network Implementation Guide for more information about SAP pairs.
