VLAN issues

[darryl.hobbs]

Hello guys. I am having trouble getting multiple vlans to come up in a 3524 switch. I have them created with an ip address and I have assigned them to a port on the switch that is up. I am unable to get any vlans other than vlan 1 to come up. When I go into the interface and do a "no shut" nothing happens. The vlans are showing active and assigned to a port that is up when I do a show vlan command.

Any ideas?

It is expected. On Xls/2950 which are layer 2 switches only, there is no need to have more than one SVI to be up/up since they do not have any routing capability and the Vlan interface is just used for management purpose(Ping/telnet/SNMP).

You say When I go into the interface and do a "no shut" nothing happens. What are you expecting to happen, i.e. what is Is it that the machines cannot talk to each other within the same VLAN? Is it that you cannot ping from one VLAN to another, for example? Do the machines you are trying to ping from have the correct gateway address configured? Or is it that you cannot bring more than one VLAN interface at a time out of shutdown. Please could you provide more details of what makes you think the VLANs are not working.

Thanks

You created the layer 3 SVI , did you create the layer 2 vlan and apply it to the interface also .

Conf t . Vlan XX ,enter . You are in vlan config mode , type state active just to make sure the vlan is active . Exit . Do a show vlan to make sure the vlan is created . Also make sure your port are setup with the correct vlan , type "switchport access vlan XX " on each interface you want to be in that vlan . You will have to have a port with an active port such as a pc connected before it will show an active state .

I have the same problem, My Cat3524 have all to work, but my int vlan 10 allways down. See the configurations:

SHOW VLAN BRIEF

10 200.0.2.0 active Fa0/22, Fa0/24

SHOW IP INTERFACE BRIEF

Interface IP-Address OK? Method Status Protocol

VLAN1 172.27.5.4 YES NVRAM up up

VLAN10 unassigned YES unset administratively down down

FastEthernet0/22 unassigned YES unset up up

FastEthernet0/24 unassigned YES unset up up

SH RUN INT VLAN 10

interface VLAN10

no ip directed-broadcast

no ip route-cache

shutdown

SHOW VER

This is normal , you are getting confused between the layer 2 vlan and the SVI (interface vlan #) . The SVI is strictly for applying an address to to be able to manage the switch so you can only have one SVI up at one time . If you shut vlan 1 and apply the address on vlan 10 and do a no shut then vlan 10 would come active and vlan 1 would shutdown . this has nothing to do with the layer 2 vlan functionality .
