6509 VLAN Creation

[kcbell]

Cisco IOS Software, s72033_rp Software (s72033_rp-ADVENTERPRISEK9_WAN-VM), Version 12.2(33)SXH1, RELEASE SOFTWARE (fc3)

Folks:

ABove is the sh ver of my 6509 router. I am trying to create a new vlan. I used the following commends and at the end no vlan was created. I have done this with another router in the past and it did work. What am I missing.

conf t
interface vlan 200
descrption test vlan
ip address 10.200.200.1 255.255.255.0
end

The router is a VTP server. When I do a sh vlan, vlan200 was not created as well as the vesion number never advnace.

Any idea? Thanks!

You need at least one access port in that vlan for it to work. Also, post a sh trunk, and maybe a sh vlan and scrubbed sh run---can't answer too much without that info...

Burtbee:

Are you saying I need at least one port on the 6509 to have vlan 200 in order for it to work?

The vlan does not show up on the show vlan.

My guess is you need to do the following:

conf t
vlan 200
state active

then see if it shows up in the show vlan output.

Lerdalt is correct you never created the layer 2 vlan , all you did is create a layer 3 SVI which is not associated with anything because the layer 2 vlan was not created follow Lerdalts instructions and put an active device on a port that is assigned into vlan 200 and it should work fine.

I configured a port with vlan 200 on the 6509 and I checked the vlan by using sh vlan and the state is active on that vlan.

if I remember right, when you set a port to a vlan that doesn't exist, it will add it into the vlan database provided the switch is a vtp server. Personally, that's not how I like to have my vlans created, I prefer to add them as I showed above, and give them a semi-descriptive name as well.

Is everything working for you now?

 

[kcbell]

I followed the steps below

conf t
vlan 200
state active

and I was able to add another layer 2 vlan. The version number changed and I was able to see the vlan on anohter switch. However, when I used the

interface vlan 200 command yesterday, nothing changed and the vlan was not added. I think the conf t, vlan 200 are the steps that I am going to use.

Thanks!

Interface vlan XX only creates the layer 3 SVI not the layer 2 vlan which is why it did not show up in a show vlan command.

Your config would look something like.

conf t

vlan 200
name MyVlan
!
interface vlan 200
description MyVlan
ip address 10.200.200.1 255.255.255.0
no shutdown
end



#sh ip int brief // should show you if the vlan is there and if its up.

Or a simple # sh int vlan 200

 

[lerdalt]

the show ip int brief command or the sh int vlan 200 command are only going to show the layer 3 interface and it's status. Need to also make certain that the vlan is in the vlan database with a show vlan.
