VLAN up/down state

[w-keener]

I'm configuring a new switch for multiple VLANs, each with their own IP range. However, only the first VLAN I configure (currently VLAN 1) will get to an up/up state. All other VLANs I've added stay in a up/down state and I'm unable to ping the interface's assigned ip address.

All of my VLANs have been added to the VLAN database and each VLAN has been assigned an IP address. I've also tried assigning a port to a VLAN, but it still remains in a up/down state. This is a 3560G switch. Here's a sh run:

interface Vlan1

ip address 10.160.0.1 255.255.0.0

ip directed-broadcast

ip pim dense-mode

!

interface Vlan10

description ZCS Server VLAN

ip address 10.150.0.1 255.255.0.0

ip directed-broadcast

ip pim dense-mode

!

interface Vlan11

description ZCS Hardwired VLAN

ip address 10.151.0.1 255.255.0.0

ip directed-broadcast

ip pim dense-mode

I'm setting this switch up from scratch and it's probably something simple. Any help is appreciated.

Thanks

In addition to assigning a port to the VLAN, do you have a device plugged into the port that is assigned to the device? To bring the VLAN completely up there needs to be at least one connected port in the VLAN (if you trunk the VLAN that will also help with the VLAN state).

Hi

Have you enabled any trunk on your switch.

The interface VLAN will be up only when there is an active port exisiting on the VLAN or there should be a trunk link which passes all those vlans

Try conencting a device to any port and assign that port to say VLAN 2 and you should see the interface coming up.

Ok guys, forgive my brain fart. :| I had searched and read through several threads that others had posted and for some reason this didn't really sink in.

I put a device up on VLAN 10 and what do ya know, "VLAN 10 state has changed to up/up". :)

Thanks guys!

Hi Keener,

Glad that you have sorted the issue out.

Secondly if your issue has been sorted out, may I request you to rate the thread and mark 'Solved Author's Issue' check box.

Thanks in advance.

I think you've only created the vlan interfaces but no vlans. Use the command "show vlan" to verify that the vlans 10, 11 are existing. If not create them

vlan 10

name test

vlan 11

name test2
