Syslog server connected on TLS May 14 17:09:07 mlxe System: SSL Syslog server 172.16.16.254:6514 is now active Syslog server Operation
Syslog server on TLS is disconnected May 14 17:18:45 mlxe System: SSL Syslog server 172.16.16.254:6514 is disconnected.
Note: This log will occur every minute if TLS Syslog server is configured on device but not running remotely i.e, when connection attempt fails Operation.

Note: This log will occur every minute if TLS Syslog server is configured on device but not running remotely i.e, when connection attempt fails.
