The device functions as an IPv6-compliant host, as well as an IPv4 host (also
known as dual stack). This enables device operation in a pure IPv6 network as

Head of Line (HOL) blocking results in traffic delays and frame loss caused
by traffic competing for the same egress port resources. The switch prevents
HOL blocking by queueing packets, such that packets in the front of a queue
do not block the packets behind if they are to be sent to different ports.
