Debug/Syslog Operation
Configuring a Syslog Server
Syslog is a client-server logging tool that allows a client switch to send event
notification messages to a networked device operating with Syslog server
software. Messages sent to a Syslog server can be stored to a file for later
debugging analysis.
To use the Syslog feature, you must install and configure a Syslog server
application on a networked host accessible to the switch. Refer to the docu-
mentation for the Syslog server application for instructions.
To configure a Syslog server, use the logging < syslog-ip-addr > command as
described below.
When you configure a Syslog server, Event Log messages are automatically
enabled to be sent to the server. To reconfigure this setting, use the following
commands:
■ Use debug command to specify additional debug message types (see
“Debug Messages” on page C-50).
■ Use the logging command to configure the system module or severity level
used to filter the Event Log messages sent to configured Syslog servers
(see “Configuring the Severity Level for Event Log Messages Sent to a
Syslog Server” on page C-59 and “Configuring the System Module Used to
Select the Event Log Messages Sent to a Syslog Server” on page C-60).
To display the currently configured Syslog servers as well as the types of debug
messages and the severity-level and system-module filters used to specify the
Event Log messages that are sent, enter the show debug command (see
“Displaying a Debug/Syslog Configuration” on page C-46).
