Using TLS for syslog, which logging host command sends syslog securely to the TLS default port?

The correct command is logging host 10.2.3.4 vrf mgmt transport tcp port 6514 because TLS (Transport Layer Security) for syslog typically uses TCP port 6514 as its default secure port, as defined in RFC 5425. Using TCP ensures reliable, ordered delivery of log messages, which is crucial for security and auditing. UDP (User Datagram Protocol) is connectionless and unreliable, making it unsuitable for secure, guaranteed delivery of syslog over TLS. Port 514 is the standard port for unencrypted syslog, whether over TCP or UDP, and does not provide TLS encryption.
