Syslog
This chapter explains the syslog screens.
16.1 Overview
The syslog protocol allows devices to send event notification messages across an IP network
to syslog servers that collect the event messages. The OMC is a syslog-enabled device that 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.
16.2 Syslog Setup
"
On the OMC, make sure the external syslog server is connected to the MGMT
port.
Click Management > Syslog in the navigation panel to display this screen. The syslog feature
sends logs to an external syslog server. Use this screen to configure the device’s system
logging settings.
