Syslog
37.1 Overview
This chapter explains the syslog screens.
The syslog protocol allows devices to send event notification messages across an IP network to
syslog servers that collect the event messages. A syslog-enabled device can generate a syslog
message and send it to a syslog server.
Syslog is defined in RFC 3164. The RFC defines the packet format, content and system log related
information of syslog messages. Each syslog message has a facility and severity level. The syslog
facility identifies a file in the syslog server. Refer to the documentation of your syslog program for
details. The following table describes the syslog severity levels.
37.1.1 What You Can Do
• Use the Syslog Setup screen ( Section 37.2 on page 281 ) to configure the device’s system
logging settings.
• Use the Syslog Server Setup screen ( Section 37.3 on page 283 ) to configure a list of external
syslog servers.
