HP X.25/9000 User's Guide HP-UX 11i v3 (5900-1523, August 2011)

Example 3:
This example explains how to format the trace file in “terse” (short) mode with no filtering.
To format the file /tmp/tracex25.TRC0 in “terse” mode, with no filtering:
/etc/netfmt -1 -f /tmp/tracex25.TRC0 | more
The output will resemble the following:
Tx board: 0 at 10:16:19.689181 Data Packet lci 64 PR: 0 PS: 0
Example 4:
This example explains how to display the contents of the encapsulated X.25 Level 3 packet in case
of XOT.
NOTE: This example assumes both SVC and PVC are available on the system.
To display the contents of the encapsulated X.25 Level 3 packet using the netfmt –x command,
complete the following steps:
1. Start nettl tracing using the following command:
nettl –start
2. Capture the TCP subsystem trace using the following command:
nettl -tn pduin pduout -e ns_ls_tcp -f /tcp
3. Run the X.25 application.
4. Stop nettl tracing using the following command:
nettl –stop
5. Format the above captured /tcp.TRC000 file using the following command:
/etc/netfmt -xNf /tcp.TRC000 > /tcp_xot_log
For SVC packets, the output will resemble the following:
