Status Monitoring and Statistics
• Message
 — The message contains the log information with text that is specific to the problem.
Local Logging
The switch maintains 1,000 messages in its internal log. You can display a snapshot of the log at any 
time by using the following command:
show log {<priority>}
where the following is true:
priority
 — Filters the log to display message with the selected priority or higher (more critical). 
Priorities include (in order) critical, emergency, alert, error, warning, notice, info, and debug. If not 
specified, all messages are displayed.
Real-Time Display
In addition to viewing a snapshot of the log, you can configure the system to maintain a running 
real-time display of log messages on the console. To turn on the log display, use the following 
command:
enable log display
To configure the log display, use the following command:
config log display {<priority>}
If 
priority
 is not specified, only messages of critical priority are displayed.
If you enable the log display on a terminal connected to the console port, your settings will remain in 
effect even after your console session is ended (unless you explicitly disable the log display).
When using a Telnet connection, if your Telnet session is disconnected (because of the inactivity timer, 
or for other reasons), the log display is automatically halted. You must restart the log display by using 
the 
enable log display
 command.
