• device-role switch—The device-role switch behaves
similar to the device-role host. For example, you can
use it as a label for a trunk port.
• device-role monitor—This device monitors network
traffic. It behaves similar to the device-role host, except
that RS packets are also sent to this interface. This
helps capture traffic.
• device-role router—Interface that connects to the
router. This interface allows incoming RS, RA, or RR
packets.
