vlans on a catalyst 4506

Hi,

on this switch, I can see vlans with show vlan command like this:

VLAN Name Status

---- --------------------------------

1 default active

2 VLAN0002 active

80 VLAN0080 active

100 DHCP_Scope_1 active

But in the running-config, I can't see the vlan names. Can anyone tell me where these are defined?

Thanks,

Must be running in vtp client mode in which case there is a server feeding this info to the client . It is not in the running config . The only time you will see it in the config is if you are running vtp transparent mode. Do a show vtp status and see what mode it is running in .

Re: vlans on a catalyst 4506

Hi Glen,

thanks for the reply. This 4506 has a supervisor engine module, so it should be running in server mode.

Also, in the running-config I can see the vlan interface defined like this:

interface Vlan1

ip address 10.1.1.1 255.255.255.0

!

interface Vlan2

ip address 10.2.2.1 255.255.255.0

!

interface Vlan80

ip address 10.10.10.254 255.255.255.0

!

interface Vlan100

ip address 10.0.0.1 255.255.254.0

But vlan names such as vlan0002, vlan0080 are not there.

regards,

Re: vlans on a catalyst 4506

Hello,

the layer 3 interface does not come automatically.. u need to manually define ip addresses for the vlans, to give layer 3 access for that vlan... just give a show vlan and make sure they are added onto the vlan database. Once it is there in the layer 2 vlan database, u can add the commands, interface vlan 80, ip address x.x.x.x , manually to make layer 3 vlan routing for that vlan... so, i guess whatever u have got in ur switch is right...

Hope this helps.. all the best..

Raj
