I am configuring an SG-350 from scratch. Upon login using factory credentials, I go to create a vlan as I am looking to segment ny switch with two vlans. I want to have 2 vlans: 1) one port on a management vlan and 2) the remainder of the ports on another vlan. Creating the vlans and doing the Port Vlan membership is straightforward. However, when I try to set an ipv4 address for the new vlan under IP management->IPv4 Interface, my web UI crashes. I ultimately need to power cycle the switch to get the UI back.
