Supported devices

IP packet tracing is supported for all network interfaces supported by TCP/IP (including loopback).

When using the MULTIPATH option of the IPCONFIG statement, packets can be sent over multiple interfaces. All of the interfaces must be traced. In this case specify an IP address to select the required packet. This statement also applies to the case where packets can be received over multiple interfaces (even if MULTIPATH is not used by this TCP/IP).

For information about the format of the packet trace command (VARY PKTTRACE) see z/OS Communications Server: IP System Administrator's Commands.
