Software Features

The device provides the ability to configure the port speed, flow control, link
aggregation, port monitor, 802.1p priority queues, and VLAN group.

Port Speed - 10/100 Mbps UTP

You can select the desired Speed and Duplex for each port. Possible settings include:
Auto, 10F, 10H, 100F, and 100H where the number 10 or 100 is the speed in Mbps, and
the H or F designates half-duplex or full-duplex. Choosing Auto enables NWay auto-
negotiation to automatically configure the port speed to match the highest speed
attainable by the device being connected. The port speed default setting is Auto.
Port Speed – Gigabit Ethernet Ports
1000BASE-SX fiber ports can operate in 1000 Mbps Full-duplex (1000F) only.
1000BASE-T ports offer four possible settings: Auto, 100H, 100F, and 1000F.
When Auto is chosen, NWay will negotiate three settings:
Speed - 100/1000 (100 Mbps connections are attainable for hardware version A2
only)
Duplex - Full/Half (Half-duplex mode is only available for 100 Mbps connections in
hardware version A2 only)
IEEE 802.3x Flow Control – Enable/Disable
Note: The hardware version (A1 or A2) can be found in the lower right-hand corner of
the management console screen.

Flow Control

Toggles flow control Enable or Disable. 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. The flow control default setting is Enable.

Port Trunk Groups

The Switch supports the use of port trunk groups. Each trunk group may contain 2 to 4
ports as members for a potential bit rate of up to 800 Mbps per trunk group. See the
discussion of Port Trunk Groups in Chapter 6 for more detailed information about
port trunk groups.

Port Monitor

Allows you to select a port to monitor activity for analysis. The Monitored Port will
mirror all activity to the Monitoring Port. This feature is useful for analyzing traffic in
ports where acute traffic congestion or other problems may exist.
