Figure 7-3. Configure Switch Stack – Advanced window

The first setting allows you to enable or disable port auto-partitioning by the Port’s Auto-Partition Capability on All Ports function. If you enable auto-partitioning on all ports, when more than 62 collisions occur while a port is transmitting data, the port automatically stops transmissions. The second setting allows you to enable or disable the Head of Line (HOL) Blocking Prevention function, which is designed to prevent forwarding a packet to a “blocking” port. Click Apply to let your changes take effect.

The information above is described as follows:

Port’s Auto-Partition Capability on All Ports This option offers Enabled or Disabled to decide whether to auto-partition a selected port and take it offline or not.

Head of Line (HOL) Blocking Prevention This option prevents forwarding a packet to 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.”
