Cisco 1720 - Can't configure VLANs

Posted on 2006-03-23

Am trying to set up a VLAN on a router and it doesn't recognise the command VLAN or VLAN database.

My IOS is "flash:c1700-y-mz.121-3". Is this the reason why and if so which IOS do I need?

    Accepted Solution

    Routers don't support the creation of VLANs unless they have a switch WIC card (i.e. HWIC-4ESW) installed in them. The router will manage the VLANs via a trunk and direct traffic. The VLAN work needs to be done at the switch.

    silly question, but are you trying to access this command in enabled mode, or Config mode?
