XMG1915-EP10 does not send syslog messages

grip

hi,

I configured syslog as follows and have a linux system on 192.168.1.230 port 51898 UDP listening for logs, but none are reveived from the switch.

I regularly receive logs from other systems on the linux syslog server above….

Hi @grip ,

Based on your screenshot, the Syslog configuration on your XMG1915-10EP appears correct. To help us identify why the messages aren't reaching your server, please try the following troubleshooting steps:

1. Test Connectivity: Navigate to Maintenance > Diagnostic in the web GUI and attempt to ping the Linux server IP (192.168.1.230) directly from the switch to confirm there is a valid path.
2. Check Local Firewall: Confirm that the Linux system's firewall is explicitly allowing incoming traffic on UDP port 51898. Since this is a non-standard port (default is usually 514), the host firewall or the syslog daemon configuration (e.g., rsyslog or syslog-ng) must be specifically set to listen on this port.
3. Trigger a Log Event: To force a log generation for testing, try logging out and back into the switch or toggling a physical port (plug/unplug a cable) and check if any packets are captured on the server via tcpdump or wireshark.

To narrow down the issue, could you share:

1. The current firmware version of your switch (found on the Dashboard)?
2. Is the switch in the same subnet with other systems and the linux syslog server?

Additionally, we replicate this case, and our syslog server receives the log from XMG1915-10EP (latest firmware version).
