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

in USG FLEX H Series

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…

    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?!

    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.

    @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
