Stackable NWay Ethernet Switch User's Guide
Module Specifies the module where the port is being
configured.
Port Specifies the port that will be configured.
Port Type Specifies the speed and cable type of the selected
port.
State Enables or Disables the port. This amounts to turning
the port on or off.
Speed/Duplex Selects the desired Speed and Duplex settings
for the port. Possibilities include: Auto, 100M/Full,
100M/Half, 10M/Full, or 10M/Half. If a Gigabit module is
being used, 1000M/Full will be displayed in this field.
Choosing Auto enables NWay auto-configuration on the port.
Flow Ctrl Toggles flow control On or Off. It is useful during
periods of heavy network activity when the Switch's buffers
can receive too much traffic and fill up faster than the Switch
can forward the information. In such cases, the Switch will
intervene and tell the transmitting device to pause to allow the
information in the port buffer to be sent. Confirm that Flow
Control is in force by checking the Status field.
Priority Selects Normal, High or Low. The Switch has two
packet queues where incoming packets wait to be processed for
forwarding; a high priority and low priority queue. The high
priority queue should only be used for data in which latency
can have adverse affects on the function of an application, such
as video or audio data, where latency can produce distorted
sounds and images. Packets in the low priority queue will not
be processed unless the High priority queue is empty. Setting
the port priority to High will deliver all packets arriving at the
port to the high priority queue, a Low setting will send them
all to the low priority queue. The Normal setting causes the
port to examine the packet for an IEEE 802.1p/q priority tag. If
no tag exists, the packet will be sent to the low priority queue.
If the priority tag field in the packet header contains a value of
