GC108PP managed switch: how to change management VLAN?
System -> Management -> IP Configuration has a text box for "Management VLAN ID". I have VLANs configured on this switch. When I try to set the value to anything other than the default of "1", I get ...

Before defining the Management VLAN ID, the VLAN must exist on the switch.
The desired management VLAN does exist on the switch and I have verified that it works.
To avoid the management access isn't lost in space (mind you there is no external serial console on these smart switches): At least define a port as an access port for the VLAN ID desired, or as a port of a trunk carrying the VLAN intended, from where you are managing or operating the network.
I had a trunk port containing the desired management VLAN, and an access port where the management VLAN was tagged. That was not sufficient. I then gave one port a PVID of the desired management VLAN, and that worked - I could set the management VLAN on the web interface (Insight is not applicable).
I think this is either a bug or a documentation bug. Nowhere does it state that you must have a port with PVID = management VLAN in order to set the management VLAN.
Thanks for your help and the insight to allow me to fix my problem.

Is this also the case for a GS108Tv3?
Is it good practice to configure a trunk with PVID=management VLAN? All other ports need another VLAN ID untagged so I cannot change PVID there.

Shouldn't be required. Give it a try and configure the GS108Tv3 Management VLAN to a VLAN different from the VLAN ID 1....

What's the idea here - having a port (the trunk port) ready to connect a PC without a VLAN config as a local management station? This would also require the same port to be configured for that management VLAN as untagged.
in the example on this thread, it appears to be a workaround to avoid an error popping up. Not something I"d expect from a random Netgear Smart Managed Switch.
