Syslog

RASLog and AuditLog infrastructure makes use of Syslog service running on the SLX device to log messages into the local file system or to remote syslog server. All external RASLog messages and all Audit logs are sent to syslog server. SLX-OS uses syslog-ng which is an open source implementation of the syslog protocol for Unix and Unix-like systems. It runs over any of the following:

UDP (default port 514)
TLS (default port 6514)

A maximum of 4 syslog servers can be configured on any SLX device. These servers can have IPV4 or IPV6 address and reside in mgmt-vrf, default-vrf or user defined VRF. The logging syslog-server command enables the syslog event capturing on the syslog server. The IP address and VRF-name are configurable parameters.

Following are sample syslog events captured at the syslog server.
