Many switches don't like VLAN1 to be removed. I typically leave it as the default VLAN, but don't use it for devices, don't put interfaces in it, etc, as I keep the best practice not to use VLAN1.

Subject: HP 1920G Delete VLAN Interface1 or change VLAN INTERFACE IP freeze management web.
Hi,
I have a HP 1920G-24G-POE (JG926A). Recently we changed our subnet schema and we add more VLAN. In this plan we add new VLAN 600 to manage all network devices. So, now we have two IP where we can manage the device. Our goal is delete VLAN1 which is no longer used or at least, indicate an IP like 192.168.25.12/31. When we did this the switch go on working fine but the web gui, console cli crash. No more pings to the administrative IP (VLAN1 and VLAN600). We upgrade to last firware but it happens the same. I don't know if it is an issue of this model or it is something corrupted in my switch. Any idea how to solve this problem?
thank you
