XMG1915-10E - EAPoL packet dropped.

solarius_

Hello,

I just installed an XMG1915-10E switch in my network and 802.1x stopped working. The client device is connected on port 3 and the authenticator on port 5.

With packet capture I observe that the EAPoL packets targeted to 01:80:c2:00:00:03 sent by the client to trigger the authentication are not forwarded to port 5 and the EAP-Request(Identity) sent by the authenticator to port 3 are not forwarded either. Do you have an idea where it could come from ? Is there any option to enable/disable to change this behavior ?

Best regards,

Hi @solarius_ ,

Please follow this article to verify your 802.1x configuration is correct.

Additionally, ensure ports 3 and 5 don't have any settings that might block EAPoL packets (like unnecessary VLAN configurations). Check that the cable connections between the devices and switch are working properly.

If authentication still fails, please capture the traffic on ports 3 and 5 for 3-5 minutes and share the capture file with us.

Hi @Zyxel_Judy ,

I checked the article you sent me but unfortunately there's no "802.1x" item on my switch "Security" menu (see the image below).

I double checked the switch settings and I don't see any particular settings that could block the EAPoL packets from going from one port to another. I captured the traffic on both sides and joined the capture files in attachment.
