Syslog Setup
46.1 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.
46.1.1 What You Can Do
• Use the Syslog Setup screen ( Section 46.2 on page 380 ) to configure the device’s system logging
settings.
• Use the Syslog Server Setup screen ( Section 46.3 on page 381 ) to configure a list of external syslog
servers.
• Use the Syslog Upload Setup screen ( Section 46.4 on page 382 ) to configure the settings for uploading
log messages.
46.2 Syslog Setup
The syslog feature sends logs to an external syslog server. Use this screen to configure the device’s
system logging settings.
