SELECT Command
The following keywords apply to the SUBNET object:
Considerations

If the SELECT command is not entered, the default mask and keyword is ALL.

If the SELECT command is specified with no mask or keywords, the ALL keyword
is assumed.

The ENV command allows you to see which SELECT keywords are currently being
used.

PTrace prints the NonStop TCP/IP VPROC version of the NonStop TCP/IP process
that is creating a trace file.

NonStop TCP/IP collects detailed location debugging information with each trace
point.

The ENV command allows you to see which SELECT keywords are currently being
used.

NonStop TCP/IP and PTrace collect and decode detailed SOCKET and internal
TCP control block information when SOCKCMD or TCP are selected for the
PROCESS object.
Examples
1. The following command sequence can be used to trace and decode SOCKET
command requests and responses during a PROCESS object trace:
TRACE PROCESS $ZTC0,TO TRACEFL,RECSIZE 750,SELECT SOCKCMD
2. The following command sequence can be used to trace and decode ARP protocol
traffic during a SUBNET object trace:
TRACE SUBNET #E1,TO TRACEFL,RECSIZE 500,SELECT (ARPI,ARPO)
3. The following command sequence can be used to trace and decode IP application
data (by providing the keyword USERDATA) during a SUBNET object trace:
TRACE SUBNET #EN1,TO TRACEFL,RECSIZE 750, &
SELECT (IPI,IPO,USERDATA)
ALL All records
IPI IP input records
IPO IP output records
ARPI ARP input records
ARPO ARP output records
LOGIC A combination of all the above records
USERDATA Used with IPI and IPO to display user data
