Setting ip address on VLAN interface? Why?

[Iago77]

Hello everybody,

we're planning to connect two switches through trunk 802.11q and both of them connected to a router.

Do I need setting ip adreess each vlan interface?

You only need to set an IP address on the VLAN interface if ytou want to manage the switch remotely via telnet etc.

If you don't wish to have remote management capability of the switch, you won't need to assign a VLAN IP address. It would mean of course you could only ever perform local management on the device (i.e. through a console connection).
