Vlan Probs with WS-3548-XL-EN

[MikeAlt]

Hi @ all,
I have a prob to become vlans running. The Szenario: Catalyst 3548 which have 4 Vlan defined. Gig-E as 802.1q uplink to an router.

interface FastEthernet0/1
switchport access vlan 10
spanning-tree portfast
!
interface FastEthernet0/2
switchport access vlan 20
spanning-tree portfast
!
!
interface GigabitEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
!
!
!
interface VLAN1
ip address 10.16.4.250 255.255.254.0
no ip directed-broadcast
no ip route-cache
!
interface VLAN10
ip address 192.168.10.2 255.255.255.0
no ip directed-broadcast
no ip route-cache
shutdown
!
interface VLAN20
ip address 192.168.20.2 255.255.255.0
no ip directed-broadcast
no ip route-cache
shutdown
!
!

The prob is that I can't reach from router site the switchports via ip. I tried also to set vlan in no shut state, but I'm not able to do this. The switch accept the command but it will not change in the config.
On each switchport i have a customer server connected and I will carry the data with his own vlan through our network. If anybody there to give me support.
Kind regards.
Mike

Is the router or switch attached to gig0/1 have 802.1q trunking enabled?

Hi, yes 802.1q is enabled.
Iam wondering why I am no able to set the vlan 10 - 30 in no shutdown state.
Switch#vlan database
Switch(vlan)#sh
VLAN ISL Id: 1
Name: default
Media Type: Ethernet
VLAN 802.10 Id: 100001
State: Operational
MTU: 1500
Backup CRF Mode: Disabled

VLAN ISL Id: 10
Name: VLAN0010
Media Type: Ethernet
VLAN 802.10 Id: 100010
State: Operational
MTU: 1500
Backup CRF Mode: Disabled

VLAN ISL Id: 20
Name: VLAN0020
Media Type: Ethernet
VLAN 802.10 Id: 100020
State: Operational
MTU: 1500
Backup CRF Mode: Disabled

=====================================================

interface VLAN1
ip address 10.16.4.250 255.255.254.0
no ip directed-broadcast
no ip route-cache
!
interface VLAN10
ip address 192.168.10.2 255.255.255.0
no ip directed-broadcast
no ip route-cache
shutdown
!
interface VLAN20
ip address 192.168.20.2 255.255.255.0
no ip directed-broadcast
no ip route-cache
shutdown
!

You can see that VLAN1 was active ( no shut )
The other VLANs are in state shutdown and I am not able to change this. I don't know why !
I think that is the problem.

That switch is layer2, so you can't set it to no shutdown. Only one VLAN (the default one) can be up on a layer2 switch. It will still operate fine with those being down, in fact they are completly un-necessary.

Hi baddos,

thx for your information. I thought it were a layer 3 switch, but it looks that i'm wrong.

The IP address you configure on anu layer-2 device is only used for management trough that ip address. This is wy you do not need and cannot set a second interface vlanx ip address.
