Configure Port - D-Link DES-3624i User Manual

Stackable NWay Ethernet Switch User's Guide
The fields you can set are:
Auto-Partition Capability on All Ports When this function is enabled, if too many consecutive collisions occur
on an individual port, the port will be blocked off until a good packet is seen on the wire. If a port is partitioned, the
Switch can only transmit data, not receive it.
Head Of Line (HOL) Blocking Prevention Enables or disables Head-Of-Line Blocking Prevention. Head-of
Line blocking occurs when a packet originating on Port 1, for instance, needs to be forwarded to Ports 2 and 3. If Port 2
is occupied (causing the packet to be held in memory until the port is free), the packet destined for Port 3 will also be
delayed, even though the port may be free. Cumulatively, these delays can have a noticeable effect on overall network
performance. Enabling HOL Blocking Prevention prevents Head-of-Line blocking from occurring, meaning that the
packet destined for Port 3 gets delivered immediately.

Configure Port

The port configuration screen allows you to change the port state in the case when you would like to partition a port due to
excessive collision, or for observation, device repair, or security reasons. Great caution, however, must be observed when
partitioning a port; you should make sure that the partitioned port is not being used as the port to control or monitor the
condition of other devices.
