Hello everyone,
I have a NetVanta 1534 Gen 2 running firmware R13.1.0.HA. I try creating the interface vlan via web and console and get same error: SW1(config)#interface vlan 20 %A new VLAN Interface could not be created.
If I delete one of the old one, I can recreate the interface, but will not let me an 11 vlan interface. Please advise. Thank you
Do you really need more than ten VLAN interfaces, or just more than ten VLANs on the switch?
VLAN interfaces are needed when the switch itself uses the VLAN interface for layer 3 routing. The routing engine in a layer 3 switch is less powerful than that of a router, so there are some limitations.
However, if you need more than ten VLANs on the switch as separate layer 2 domains, this isn't a problem. Just add the VLAN in global configuration. You don't need a VLAN interface. If in fact you're trying to do layer 3 routing among more than ten routed interfaces, you may need to trunk from the switch to a router and do the routing there.

Yes, but we have multiple locations that I want them to receive their IP address from the Windows DHCP server, if I don't create the virtual interface, how will the traffic be routed? L2 Vlan will not work, or am I missing something?
Create a trunk to the Windows server and assign each VLAN subinterface on the Windows server an IP within the subnet.
Thank you jayh in that case I would not need to vlan interface because because the vlan will use the ip helper will broadcast the dhcp traffic and the DHCP is whom will be assigning the vlan IP. Thank you for your assistance
