Can anyone tell me what affect adding a new vlan to a pool has on existing clients on the network please? Does the controller re-hash all the existing clients at the time when you make the change or does it only re-hash when the client reauthenticates? The test that I tried resulted in the client losing network connection, it looked like the client was moved to another vlan but the client didn't dhcp so lost network connectivity. Is this expected behaviour? Turning the wifi off and back on, hence reauthenticating and dhcping fixed the issue but I don't really want our users to have to do this.
I need to do this in our live environment that has up to 13000 clients so need to know how it will affect them.
Thanks
Do not do in a live environment. All clients get kicked off so that they can be placed into correct hashed vlans, but it is far from invisible, so it should be done in a maintenence window.
