AndrewT

Hello, i have exactly the same issue as described here

https://community.zyxel.com/en/discussion/11102/sfp-p1-port-does-not-work-lind-down

But device is Zyxel VPN50 (V5.37(ABHL.2) firmware) with ZyXEL SFP-1000T 1000Mbit / s SFP network transceiver module. Is it possible to get it work?

Hi @AndrewT ,

It could be related to device boot module. Can you take a screenshot of boot module version and sent me via private message.

How to check boot module:
Router# psm
Router(psm)# atsh

Hi @AndrewT ,

We've tested the following configuration on our end:

• VPN50 (boot module 1.13)
• Connected to ZyXEL SFP-1000T
• DHCP provided by other firewalls
• Port 1 successfully obtains an IP address

With this setup, we were unable to reproduce the issue you reported.

To help us investigate further:

Please check your private messages for instructions and share remote access information, so we can examine your specific configuration.

Please note: The VPN50 has reached its End of Life (EOL) for firmware development. While we can't provide new firmware updates, we'll explore potential configuration recommendations or workaround solutions for your situation.
