In z/OS® V1R13 Communications Server, the DISPLAY NET,EEDIAG,TEST=YES,LIST=SUMMARY command output does not provide detailed routing information for Enterprise Extender (EE) connections. Instead, command processing expedites the EE connectivity test results. Quicker results might be beneficial to you if your IP configuration includes firewalls that block Internet Control Message Protocol (ICMP) messages, which results in delayed EE connectivity test results. The DISPLAY NET,EEDIAG,TEST=YES,LIST=SUMMARY command does not require ICMP messages to flow to verify basic EE connectivity. The DISPLAY NET, EEDIAG,TEST=YES,LIST=DETAIL has not changed; it still requires ICMP messages to flow in order to display the routing information for the EE connection.
