Logging
Summit 300-48 Switch Software User Guide 139
• 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.
Remote Logging
In addition to maintaining an internal log, the switch supports remote logging by way of the UNIX
syslog host facility. To enable remote logging, follow these steps:
1 Configure the syslog host to accept and log messages.
2 Enable remote logging by using the following command:
enable syslog
3 Configure remote logging by using the following command:
config syslog {add} <ipaddress> <facility> {<priority>}
Specify the following:
Port Port management-related configuration. Examples include port
statistics and errors.
