Setting Telnet session defaults

Session logging is disabled by default, and the event level is set to information (info) or higher. To enable
event logging to Telnet sessions and change the default event severity level, use the following command:
set log sessions severity severity-level enable
(For information on severity levels, see Table 48 on page 771.)
To disable session logging, use the following command:
set log sessions disable

Changing the current Telnet session defaults

By default, log information is not sent to your current Telnet session, and the log level is set to information
(info) or higher. To modify the severity of events logged to your current Telnet session, use the following
command from within the session:
set log current severity severity-level
(For information about severity levels, see Table 48 on page 771.)
To enable current session logging, type the following command:
WSS# set log current enable
success: change accepted
To disable current session logging, type the following command:
WSS# set log current disable
success: change accepted

Logging to the trace buffer

Trace logging is enabled by default and stores debug-level output in the WSS trace buffer. To modify trace
logging to an event level higher than debug, use the following command:
set log trace severity severity-level
To disable trace logging, use the following command:
set log trace disable
success: change accepted.
(To display the trace log, see “Stopping a trace” on page 777. For information about the trace function, see
“Running traces” on page 776.)

Enabling mark messages

You can configure WSS Software to generate mark messages at regular intervals. The mark messages indicate
the current system time and date. Nortel can use the mark messages to determine the approximate time when a
system restart or other event causing a system outage occurred.
