Hello,

I've looked through all the threads here seaching for VLAN shutdown, but unfortuantly the results didnt show the answer that helped me. Can anyone help with the following situation

Using a Cisco Catalyst 3500XL 48 port, Fast ethernet.

The 3500 has two gb ethernet ports, connecting it to other 3500 XL's - 6 in total, all stacked together.

I am trying to create a new, seperate VLAN with a different IP range. I think the VLAN has been created correctly, however I cannot start it - it is shut down. I have set the 'no shut' command on VLAN 2, but I notice when running sho int vlan2 that the line protocol is also down, and I believe this to be the main cause of the issue. Can anyone point out what I am missing / not doing?

There are only two ports that are members of VLAN2, ports 29 and 30. All the others are members of the default VLAN and have no special settings.

Here is the config:

Here is the sho int vlan2 output:

hostname#sho int vlan2
VLAN2 is administratively down, line protocol is down

ARP type: ARPA, ARP Timeout 04:00:00


A "show" vlan command:

Hostname(vlan)#show
VLAN ISL Id: 1
Name: default
Media Type: Ethernet
VLAN 802.10 Id: 100001
State: Operational
MTU: 1500

VLAN ISL Id: 2
Name: VLAN2
Media Type: Ethernet
VLAN 802.10 Id: 100002

MTU: 1500

I belive the VTP mode is currently set to 'transparent'. Finally, a show vlan output:

I would REALLY appreciate any information you can give regarding getting the 2nd VLAN up and working!

Thanks.

 
The 3500XL is only a Layer-2 switch and cannot route between VLAN's. It can have many Layer-2 VLANs configured but only a single Layer-3 VLAN Interface that is used purely for management. If you do a 'no shut' on the VLAN 2 interface it will put it in the UP state (as long as a port configured in that VLAN is up) but it will shut the VLAN 1 interface.
To route between VLAN's you will need an external Layer-3 switch or router.
