On most PowerConenct switches you would actually change the management VLAN using this command. console(config)#ip address vlan 10 However the 35xx switches don’t have this command. The commands you outlined will assign an IP address to VLAN 10, and you should be able to use that IP address to access the web GUI to manage the switch.
Is possible to set VLAN different from VLAN 1 as management VLAN on Powerconnect 35xx? I can't try it at the moment as I don't have the hardware. I suppose this configuration: Can someone who did it in reality confirm that it works? Thanks.
