API Guide

● tcp | udp | tls port-number — (Optional) Send syslog messages using TCP, UDP, or TLS
transport to a specified port on a remote logging server, from 1 to 65535.
● severity-level — (Optional) Set the logging threshold severity:
○ log-emerg — System is unusable.
○ log-alert — Immediate action is needed.
○ log-crit — Critical conditions
○ log-err — Error conditions
○ log-warning — Warning conditions
○ log-notice — Normal, but significant conditions (default)
○ log-info — Informational messages
○ log-debug — Debug messages
● vrf {management | vrf-name} — (Optional) Configure the logging server for the management

Defaults
System logging to a remote server is not configured. When configured, system messages are sent over
UDP to port 514 on a remote logging server by default. System messages of severity-level log-notice
and lower are sent.
Command Mode CONFIGURATION
Usage
Information
Use the logging server command to forward log messages to syslog servers for storage.
The tls option requires that a valid security profile is already configured with the logging
security-profile command. If you delete the logging security profile, system messages are sent
using UDP (default) to a remote syslog server.
Supported on the MX9116n and MX5108n switches in Full Switch mode starting in release 10.5.0.0. Also
supported in SmartFabric mode starting in release 10.5.0.1.
The no version of this command deletes the syslog server.
