Syslog
• 4—warning
• 5—notification
• 6—informational
• 7—debugging
By default, the switch logs normal but significant system messages to a log file and sends these messages
to the system console. Users can specify which system messages should be saved based on the type of
facility and the severity level. Messages are time-stamped to enhance real-time debugging and
management.
Enabling Logging for Telnet or SSH
System logging messages are sent to the console based on the default or configured logging facility and
severity values.
Users can disable logging to the console or enable logging to a given Telnet or SSH session.
• To disable console logging, use the no logging console command in global CONFIGURATION
mode.
• To enable logging for Telnet or SSH, use the terminal monitor command in EXEC mode.
Note Note: When logging to a console session is disabled or enabled, that state is applied to all future console
sessions. If a user exits and logs in again to a new session, the state is preserved. However, when logging
to a Telnet or SSH session is enabled or disabled, that state is applied only to that session. The state is
not preserved after the user exits the session.
The no logging console command shown in Example 2-4 does the following:
• Disables console logging
• Enabled by default
Example 2-4 no logging console Command
switch(config)# no logging console
The terminal monitor command shown in Example 2-5 does the following:
• Enables logging for Telnet or SSH
• Disabled by default
Example 2-5 terminal monitor Command
switch# terminal monitor
