Hi, it is my first post, sorry but my english is very bad!!! I want to know how am i do to change the Vlan1`s IP address because the actual ip will be used in another vlan. Actually i haver 10 vlans in L3 mode (routing) implemented in it.

I hope you understand me!!

Hi Javier. If I understand correctly, you have the switch in layer 3 mode and you want to change the IP address of the vlans. The very first thing you must do is ensure that the vlan 1 has a static IP address.

After you have created the vlans, go to System -> System Management -> IP Addressing -> Ipv4 interface

Click edit for the first vlan and simply make it what you like..

Then go ahead and create the second IP interface. It is 100% important that you make the vlan 1 IP address first otherwise you will 'lock up the switch' and won't go anywhere.

Thanks Tom!! But the idea is ONLY change the VLAN1 IP address by ANY other IP that I want. If you go to Interface IPv4 setting panel is possible to change the IP of existing ones via a dropdown menu but I can not type any IP, i can only choose IP of an existing VLAN (I can`t type any address because it is a dropdown menu)

I hope you undersand, sorry!

Hi Javier, if it is problematic this is what to do:

Use a telnet enabled computer

telnet the IP address of the switch

Log in with user and password

Press and hold ctrl then hit Z

type in command LCLI

Log in to the switch

Type-

configure

interface vlan 1

ip address x.x.x.x  x.x.x.x

exit

exit

copy run start

first x.x.x.x = ip  second x.x.x.x = subnet mask

Let me know if this works.

Great Tom!!! I will try it!!

I did not know that there was a CLI (LCLI) in this switch, I understand that is the only way to make the change I need, is not possible with web interface!!. I learned something new! It was very useful reply, Thanks!

Best Regards!!

Please be warned, the information provided is unsupported by Warranty and if you damage the flash of the switch through the CLI you may be turned down for support.

I will tell you from personal experience if you mistype a command it is very easy to make the switch crash. Use this function only if you HAVE TO.

Tom, 

  I have followed your instructions but when I do this I get "duplicate ip on interface" I am trying to change the IP of VLAN 1 as the ip is already in use by another switch.
