Cisco 1720 - Can't configure VLANs

Hi,

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?

cheers,

YVS.

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