CHAPTER 48
Syslog
This chapter explains the syslog screens.
48.1 Syslog Overview
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.
Table 158 Syslog Severity Levels

3 Error: There is an error condition on the system.
4 Warning: There is a warning condition on the system.
5 Notice: There is a normal but significant condition on the system.
6 Informational: The syslog contains an informational message.
