Which UDP port is used for the transmission of Syslog data?

Syslog messages utilize UDP port 514 for transmission. Syslog is a standard for message logging in a network, allowing network devices and servers to send event notification messages across the network. Using port 514 enables systems to receive log messages from various devices, facilitating centralized logging and monitoring.

The other port choices are used for different protocols. Port 69 is associated with Trivial File Transfer Protocol (TFTP), which is used for transferring files without authentication. Ports 161 and 162 are used for Simple Network Management Protocol (SNMP); port 161 is for sending requests to the SNMP agent, while port 162 is used for receiving SNMP traps or notifications from managed devices. Hence, these ports are not relevant for Syslog communication.
