Modifying options with VARY commands
After starting an OSAENTA trace, you can change the trace using the VARY command. For example, if you want to change the trace to abbreviate the data being traced, use the following command:
V TCPIP,tcpipproc,OSAENTA,ON,ABBREV=480
You can display the results of the VARY command using Netstat:
netstat -p TCPCS -d
DEVNAME: OSAQDIO4 DEVTYPE: MPCIPA
DEVSTATUS: READY
LNKNAME: LOSAFE LNKTYPE: IPAQENET LNKSTATUS: READY

If you are a TSO user, use the NETSTAT DEVlinks option.
You can use the VARY TCPIP,tcpproc,OBEYFILE command to make temporary dynamic
changes to system operation and network configuration without stopping
and restarting the TCP/IP address space. For example, if you started
the address space TCPIPA and created a sequential data set USER99.TCPIP.OBEYFIL2
containing OSAENTA statements, issue the following command:
VARY TCPIP,TCPIPA,CMD=OBEYFILE,DSN=USER99.TCPIP.OBEYFIL2
The VARY TCPIP,,OSAENTA command is cumulative. You can trace
all packets for specified IP addresses by entering multiple OSAENTA
commands. In the following example, the five commands disable the
current trace, clear any previous trace filters, trace all the frames
received and all the frames sent for the specified IP addresses, and
activate the OSAENTA trace facility.
VARY TCPIP,,OSAENTA,OFF,PORTNAME=OSA4
VARY TCPIP,,OSAENTA,CLEAR,PORTNAME=OSA4,ABBREV=200,FRAMES=8000
VARY TCPIP,,OSAENTA,PORTNAME=OSA4,IPADDR=10.27.142.44
VARY TCPIP,,OSAENTA,PORTNAME=OSA4,IPADDR=10.27.142.45
VARY TCPIP,,OSAENTA,ON,PORTNAME=OSA4
