Lesson 4.4 (Switched Virtual Interfaces - Part 1): didn't work for me. I couldn't create a virtual interface on the switch. After a few attempts, I clicked on "Perform this for me". This time, the interfaces were created successfully, and the appropriate IP addresses were assigned, but when I tried to ping computers on different VLANs, the pings failed. I'm using Safari 10.1.2 on MacOS 10.10.5.

Hi Dmitry,
Thank you very much for reporting this. A recent update to Layer 3 features introduced a bug. This has now been corrected. Thanks again for reporting it!

Hi Dmitry, also, please note that on Safari, auto-correct is enabled by default. ("vlan" gets auto-corrected to "van"). Were you getting an "Invalid input detected at '^' marker" error?
