Figure 7-3. Configure Advanced Switch Features window
The Switch features head of line (HOL) blocking prevention, a function designed to prevent forwarding of a
packet to a "blocking" port, that is, a port where an excess of packets are queued up. Note that when a
multicast packet or a packet with an unknown destination address needs to be forwarded to several ports, and
if some of them are "blocking," the packet will not be discarded, rather it will be forwarded only to the ports
that are not "blocking." Toggle between Disabled and Enabled before clicking Apply to let your change take
effect.
