Syslog is a standard for logging program messages. It allows separation of the software that generates messages from the system that stores them and the software that reports and analyzes them. It also provides devices which would otherwise be unable to communicate, a means to notify administrators of problems or performance.

OcNOS supports logging messages to a syslog server in addition to logging to a file or the console (local or ssh/telnet console). OcNOS messages can be logged to a local syslog server (the machine on which OcNOS executes) as well as to one or more remote syslog servers (maximum of 8 remote syslog server is supported). Remote syslog servers can either be configured with IPv4/v6 addresses or host names.

OcNOS supports syslog over the default and management VRFs via in-band management interface and OOB management interface, respectively.

By default, syslog runs on the management VRF.
