Notes

I posted this some time ago on my Mastodon page, but forgot to post it here.

I tried to access devices on a different subnet connected to an Aruba Instant On switch. It didn't work. It was a different IP subnet, but the same VLAN.

As it turned out, there is a feature named "Network Protection". It seemed to filter out everything from other subnets. After disabling it, everything was fine.
