Syslog Setup
29.1 Syslog 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.
29.1.1 What You Can Do
Use the Syslog Setup screen ( Section 29.2 on page 209 ) to configure the device’s system logging
settings and configure a list of external syslog servers.
29.2 Syslog Setup
The syslog feature sends logs to an external syslog server. Use this screen to configure the device’s
system logging settings and configure a list of external syslog servers.
