[explorer1979Jimmy]

Hi all,

I just bought a SG300-28, it is upgrade to the latest version firmware.

And then I am change it work on L3 Mode (Yes, I need it much work on L3 Mode)

Ok, but when I go to IP Configuration Page on the VLAN 1 (Please see the image)

Edit it to static can't let me change it IP (Yes, it is now working on DHCP mode, and get a IP from my Firewall auto, it is IP 192.168.218.37 there)

How do I force the VLAN1 or Port 1 is IP 192.168.218.3 by GUI or by other way?

Hi Jimmy, the easiest and fastest way to do this is in the CLI.

If you don't have a console, you can use telnet. To enable the telnet go to Security 0> TCP/UDP services, check the box for telnet and apply this.

Once done, telnet to the switch and log in

use the commands

config t

interface vlan 1

ip address x.x.x.x x.x.x.x  (x.x.x.x = ip addresss and the second x.x.x.x = the mask something like 192.168.218.3 255.255.255.0)

Tom,

Thank you very much.

But, one more question ...

How to CLI save the running-config to the flash, so on future reboot will not lose anything on it?

Hi,

For Web GUI based setup I think this article's Change the IP Address of the Switch section would be helpful
