EXTERNAL INFLUENCES

International Code Set Support

Single and multibyte character code sets are supported in data; single-byte character code sets are sup-

ported in ﬁle names.

EXAMPLES

1. Initialize the tracing/logging facility:

nettl -start

(See note for the -start option.)

2. Display the status of the tracing/logging facility.

nettl -status all

3. Change log class to

error and warning for all the subsystems. disaster logging is always on

for all subsystems.

nettl -logew-eall

4. Turn on inbound and outbound PDU tracing for the transport and

session (OTS/9000) subsys-

tems and send binary trace messages to ﬁle

/var/adm/trace.TRC000

nettl -traceon pduin pduout -entity transport session \

-file /var/adm/trace

5. Turn on outbound PDU tracing for X.25 level two and subsystems ns_ls_ipv6

and ns_ls_ip.

Trace messages go to the trace ﬁle set up in the previous example. This example also uses the

abbreviated options. Tracing for X.25 requires a

-card option to indicate which X.25 card to trace.

nettl -tn pduout -e SX25L2 ns_ls_ipv6 ns_ls_ip -c x25_0

6. Determine status of tracing from the previous two examples.

nettl -status trace

The output should resemble the following:

Tracing Information:

Trace Filename: /var/adm/trace.TRC*

Trace file size(Kbytes): 1000

Trace memory allocated(KB): 512

Trace memory to be allocated(KB): 0

Messages Dropped: 0

Processor ID: -1

Subsystem Name: Trace Mask: Card:

TRANSPORT 0x30000000

SESSION 0x30000000

NS_LS_IP 0x10000000

NS_LS_IPV6 0x10000000

SX25L2 0x10000000 x25_0

7. Stop tracing for all subsystems.

nettl -traceoff -e all

8. Enable pduin and pduout tracing for ns_ls_driver (LAN driver) subsystem. Binary trace

data goes to ﬁle /var/adm/LAN.TRC000.

The

-file option of this command is only valid the ﬁrst time tracing is called. The trace ﬁle is not

automatically reset with the -file option. To change the trace output ﬁle, stop tracing and start

up again. This example assumes that the -traceon option is being used for the ﬁrst time.

nettl -tn pduin pduout -e ns_ls_driver -file /var/adm/LAN
