IPSTACK - IP stack display
The IP stack display lists the TCP/IP stack configuration settings.
The data for this report is only available if a CKFREEZE file has been created
during an APF-authorized run of zSecure Collect (CKFCOLL) with option
TCPIP=YES. For information about creating this file, see zSecure Collect for z/OS.
Detailed field information is available by pressing PF1 on an IP report selection panel or on any field within a panel. Descriptions are also provided in zSecure CARLa SELECT/LIST Fields:
- For the IP configuration data field names and descriptions for IP* NEWLIST types, see
IP: Information about TCP/IP configuration
. - For information about the IP configuration data fields used for SMF event reporting (SMF record 119, subtype 4), see .
The batch report to review the IP stack is CKALSIP. The interactive report is called CKADSIP.
Sample overview and detail display panels for the IP stack report are shown in Figure 1 and Figure 2.
