Catalyst 6500 VLAN Configuration

[Cedrick]

Hi,

I'm setting up a new 6509 with redundant SUP720/MSFC3's running in native mode, IOS version 12.2(17d)SXB11a. I'm unable to get traffic to pass thru VLAN 4 (which is the first VLAN I've configured). I assigned an IP address and issued no shutdown within interface VLAN 4. I gave GigabitEthernet8/48 switchport access and issued the switchport access vlan 4 and switchport mode access commands within interface gi8/48.

When I do a sh vlan, I don't even see VLAN 4 listed. If I do a sh ip int brief VLAN 4's status is displayed as down. Gi8/48 is up, up. Shown below is a truncated config and the sh vlan, sh ip int brief, and sh int gi 8/48 commands.

I'm sure it's something simple, but I've only configured 6500's in hybrid mode and 3560's using native IOS. Any help would be greatly appreciated and sorry for the newbie-ness!

Yes, newbie mistake. You have to create the vlan first (I thought I was assigning an IP address to it as you do in the 3560's, but this isn't so).

1) Create VLAN
- conf t
- vlan <#>
- end

2) Assign IP
- conf t
- int vlan <#>
- ip address <IP> <mask>

3) Assign port
- conf t
- int <type> <blade/port>
- switchport
- switchport access vlan <#>
- switchport mode access

Yup create the layer 2 vlan first then create the layer 3 interface for that vlan . Also you can put an ip address on the port itself if need be , just use the no switchport" command on the interface and this makes it a routed interface.
