Updated 25.11.15
Firmware WB.15.18.0007 resolves the issue, see below
A colleague of mine found an issue with the latest HP 2920 switch firmware.
If you create VLANs using the CLI Menu, the switch reboots and the configuration is not saved.
We have reported this to HP, but is currently being treated as a non critical issue as when creating a VLAN via the web interface or native CLI, the issue doesn’t happen.
We have also noticed on this firmware the switch seems to be less responsive. Luckily we had a few units in stock that we could replicate this issue on, and can confirm downgrading to the previous firmware version removes the issue.
A quick cheers to my colleague Marco for finding and researching this issue.
