What is the common UDP port for syslog?
UDP port 514
Syslog runs on UDP, where syslog servers listen to UDP port 514 and clients (sending log messages) use a port above 1023. Note that a syslog server will not send a message back to the client, but the syslog log server can communicate, normally using port 514.
What port is 514 used for?
| Name: | syslog |
|---|---|
| Purpose: | Remote system event logging |
| Description: | A syslog server opens port 514 and listens for incoming syslog event notifications (carried by UDP protocol packets) generated by remote syslog clients. Any number of client devices can be programmed to send syslog event messages to whatever servers they choose. |
Does syslog use UDP?
When operating over a network, syslog uses a client-server architecture where the server listens on a well-known or registered port for protocol requests from clients. Historically the most common transport layer protocol for network logging has been User Datagram Protocol (UDP), with the server listening on port 514.

Which is the default port number for syslog?
The port number is defined as 514 with UDP protocol for syslog services. There is also a recommendation about source port to be UDP 514 too. This port number also registered by IANA to the syslog protocol which means other applications can not use 514 as official default port.
How to use Cisco remote syslog on different UDP / TCP ports?
Cisco Remote Syslog on different UDP/TCP Port,, possible? I have a couple of Cisco 2960’s sending syslog messages to a remote syslog-ng on port 514 (standard). I need to set another Swtich so it sends traffic to the same syslog server but on another UDP port (such as 714),, is that possible,?
How do I send a syslog message on my router?
To send messages via syslog, you must perform the following sequence of steps on the device: Globally enable logging on the router or switch using the logging on configuration command. By default, in Cisco IOS software, logging is enabled; however, it is only enabled to send messages to the console.
How big does a syslog message have to be?
The syslog client sends syslog messages to the syslog sever using UDP as the Transport Layer protocol, specifying a destination port of 514. These messages cannot exceed 1024 bytes in size; however, there is no minimum length.
