17.2. PKTTRACE parms

There are 2 ways to add parms to the SYSTCPDA CTRACE (PKTTRACE). The first way will AND the parms together and the second way will OR the parms together, as follows:

• V TCPIP,tcpipproc,PKT,SRCP=21,DEST=1236

  In this example only packets with source port=21 and destination port=1236 will be traced.

• V TCPIP,tcpipproc,PKT,SRCP=21

  V TCPIP,tcpipproc,PKT,DEST=1236 *note 2 VARY commands*

  In this example packets with a source port=21, regardless of dest port, *and* packets with dest port=1236, regardless of source port will be traced.
