Log
The Syslog Protocol allows devices to send event
notification messages in response to events, faults, or
errors occurring on the platform as well as changes in
configuration or other occurrences across an IP network
to syslog servers. It then collects the event messages,
providing powerful support for users to monitor network
operation and diagnose malfunctions. 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.
