You need two things to display an L2 map.
You're quite right that you need a license - the L2 license is separate from the L3 license.
You also need to gather the necessary data. Please note that the L3 map depends only on configuration files, which you can import using many different methods. For the L2 map, you need more data - the configuration files alone will not work. Normally, you will need to use a "live" data collection task, via ssh, to log directly in to the routers and switches in the subnet, so that RedSeal can get up-to-date ARP and MAC information. Without the ARP and MAC information, we cannot draw an L2 map.Reply
