Netvanta 1234 enabling new vlan

Jump to solution

I have a simple configuration where I needed to create a new vlan 100 for IP phones. When vlan 100 was created it automatically configured the interface in shutdown. When I try to enable or no shutdown vlan 100 the switch does a shutdown on all other vlans. What am I missing this seems simple. I basically have vlan 1 and 100 and I need them both enabled.

You may have multiple vlans on a layer 2 switch but only one active (not shutdown) vlan interface on a switch.

Is this problem because I created vlan interfaces for both vlans and assigned IP addresses for each. The IP addresses are in different subnets such as vlan 100 10.10.40.x/24 & vlan 1 192.168.4.x/24. Am I only allowed to create vlan 100 and place ports into it, but avoid creating an interface vlan 100 with an IP address?

To be sure I understand then I can create multiple vlans on this switch and route between them external, but only 1 of these vlans can be associated with an interface and IP address.

You are correct.  As you may already know, you will need to use a vlan trunk switchport which is connected to the layer 3 device which is configured with subinterfaces with vlan tagging.  this will enable you to correctly route all vlans.
