Catalyst 3850, added new VLAN, but doesn't display in 'show vlan'

corpengineer818

We have a Catalyst 3850 switch stack, connected to an ASA-X5545 via Etherchannel.  Working just fine for a few dozen VLANs.  However when I add an addition VLAN, it does not seem to work.

 

Think I am missing something basic here.

 

After I added interface vlan 200 ('interface vlan 200', and 'no shutdown') on the switch, it does not appear in 'show vlan'.

And if I type 'show span vlan 200', it errors out 'Spanning tree instance(s) for vlan 200 does not exist'.

 

Any assistance would be appreciated.

 

Thank you.

Hi

You have to make that switch stack the primary vtp server before you can create the vlans using the following command:

vtp primary

Have a look at the following doc:

Thanks

HI,

Have you created the vlan before adding the interface vlan 200?

e.g.

vlan 200
 name vlan_200

 

Thanks

Appreciate the prompt response, thank you.

'vlan 200'

It displays:

VTP VLAN configuration not allowed when device is not the primary server for vlan database.

Hi,

You are using VTP version 3. Which switch is your primary server in your network. You will need to create the vlan 200 on the VTP primary server.

We have (1) switch stack w/ (4) 3850 switches.  Switch #1 is 'Active'.  We do not have any other switches connected to the stack.  Thought that the switches in a stack share a single configuration?

It worked.  Thank you very much.  Thank you to Inayath as well.

Hi,

Okay lets try this:-

1- Can you try to create the same vlan on all the switches and see if you hvae the problem seeing it on all the switches? (Show vlan id 200)

Confg: conf t

            vtp primary

            vlan 200

show vlan id 200

 

2- Coming down to only this switch:- Can you post the output of show vlan id 200?

 

(Also show us the config pertaining to vlan200).

 

HTH

Regards

Inayath
