Free-play 3 device tabs

Free-play Cisco IOS console

Three tabs, three different device kinds — each with its own state and its own IOS command set. Type vlan 10 on the router and it's rejected. Type router ospf 1 on the L2 switch and it's rejected. The L3 switch accepts both. Everything else — enable, configure terminal, interface, ip address, show running-config — works everywhere.

Click a tab to switch devices — each keeps its own transcript. ? for help. ↑ / ↓ for history.
