Removing IP on Default VLAN (Live LAN).

[Karl Collinson]

Morning\Afternoon All,

I have 2 procurves running currently only the default vlan.

The Procurves are linked via Fibre.

I need to change the subnet of the default VLAN on both Procurves.

Would would happen to traffic passing through both switches when i remove and assign a new ip address to both Default VLAN switches?

Thanks,
Karl.

if you run only default vlan on your two switch this switches make only L2 operation

you don't make concern for network traffic
connect consol cable on your switch and you write
vlan1#no ip address xxx.xxx.xxx.xxx/xx command
after you make assign new ip address
vlan1#ip address xxx.xxx.xxx.xxx/24

or

you can assign new(second) ip address on your default vlan after delete old(frist) ip address on default vlan each switch

vlan1#ip address 111.111.111.111/24(new)
after

vlan1#no ip address 222.222.222.222/24(old)

Thx for your relpy.

The prog of the switch is a breeze.

Just need to ensure that any live connections from any Terminals on Switch A over the Fibre link to the terminals on Switch B will not have there connections dropped when i remove the IPs from the Default VLANS before assigning the new Default VLAN IP.

Thx,
Karl.

hi Karl
if you can't routing operation on switch
don't worry
only L2 operation on switch vlan ip addres for only managemet
