Hello,
SF300-24P is losing the default-gateway config when I change the ip address of the management vlan. It happens for address or mask changes, no matter if the default-gateway is still reachable.

Please ensure that the port through which the device is managed has the proper
settings and is a member of the new management interface.

I have to reapply the "ip default-gateway 10.9.12.1" in order to get network back. This makes a simply ip address change quite difficult for a remote switch.
I used ipv6 connection as a workarround but I think this is not a completely final solution.
Is this a bug, known issue or simply a limitation?
