I've upgraded from a Vigor 2860 to a 2136ax for the firewall throughput. I'm trying to enable port mirroring for some diagnostics, but I can find no interface for it in firmware 5.3.0.2. The article at https://www.draytek.co.uk/support/guides/kb-port-mirror lists 2136ax as a model that supports mirroring, but the instructions refer to a previous firmware version and the interface is quite different to the current one.
I port mirroring actually supported? How do I enable it?

Thanks

No, doesn't look like that feature exists on that model.

But it's early days for these DrayOS v5 firmwares - so maybe you should ask support and suggest it as a feature ?
