Incredible things and where to find them - All VLAN interfaces were broken

Mk88_it

Following i'll tell my bad story…

I have a Flex500H and under Network Interfaces - interface - general I see these two items eth101 and eth102

Under Network - Interface - advanced settings - general there is nothing instead

So, my (BAD) idea was: I can try to recreate these interfaces end then delete them to remove the orphaned entries.

And so.. I did, but after the Zywall's confirmation message, ALL the VLAN interfaces were broken!

I rebooted the device and finally I opened every VLAN interface (both enxternal and internal), changed the description simply adding one character, and this has solved the situation and all VLAN came back to life……

What's going on?! Please give me an explanation…

Update:

This issue is because the ports 1 and 2 are individual ports. For USG FLEX 500H and 700H, some ports are defined as individual ports (for more information, please reference the User's Guide P111 and 112. Since then, these ports require an ethernet interface before creating a VLAN interface. If you remove the default ethernet interface and create a VLAN interface, the system will automatically create the ethernet interface "eth10X" to ensure the system works. Our product team is evaluating the display adjustment and will enhance it in the future firmware release.

I don't have flax but if you create a backup file from the maintenance>backup … Then search thro the settings for such as 'ethernet' or 'vlan' or 'interface' if you get the idea.

Yes, there are present in the config file, but the question is: how can I manage them from the gui?

And, why does zywall allow me to recreate them from the gui if they are already present in the config?

Moreover, why did this operation break all my vlan interfaces?!

Might be only be to do with your model?

Mk88_it

yes, maybe…i'm waiting answare from zyx staff…

Hi @Mk88_it,

This issue is because you can't configure "eth101" or "eth102" as the interface name. Is it possible for you to rename the interfaces? For example, "eth_101" is working on my side.

Mk88_it

@Zyxel_Melen thank you for the answer . As i wrote in my first post, i can do nothing for these interfaces because i don't see them under "Network - Interface - advanced settings - general"

Especially because i never created them in the first place

I see them ONLY under Network Status - interface - general and in the configuration file

Zyxel_Melen

Hi @Mk88_it,

So these two interfaces were created before? If so, I will ask our engineer to help generate the correct configuration file for you to upload. Could you share the configuration file with me? I will send you a private message for the request.

If not, I will also send you a configuration file without these interfaces.
