MULTILINK ML1600 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL 9–15
• Auto-Neg sets auto negotiation for 100 Mbps and Gigabit copper ports. There is no no
auto negotiation for fiber ports as their speeds are fixed.
• The Port Speed sets the speed to be 10 or 100 Mbps. This settings works only with 10/
100 ports; it is ignored for 10 Mbps ports.
• The Duplex setting selects full duplex or half duplex capabilities for 10/100 Mbps
ports.
• The Back Pressure displays the state of the back pressure setting on the port. This
value can be edited in this window.
• The Flow Control displays the state of the flow control setting on the port. This value
can be edited in this window.
• Priority displays the priority set for the port. This value cannot be edited in this
window.
• The VLAN ID displays the VLAN set for the port. This value cannot be edited in this
window.
• The STP State displays the STP settings for the port. This value cannot be edited in this
window.
• The Tagged State displays the Tag settings on the port. This value cannot be edited in
this window.
• The GVRP State displays the GVRP settings on the port. This value cannot be edited in
this window.
• The LLA indicates the state of the Link Loss Alert feature.
The “Auto” (default) value for the Port Speed senses the speed and negotiates with the port
at the other end of the link for data transfer operation (half-duplex or full-duplex). The
“Auto” value uses the IEEE 802.3u auto negotiation standard for 100Base-T networks. If the
other device does not comply with the 802.3u standard, then the port configuration on the
switch must be manually set to match the port configuration on the other device.
Possible port setting combinations for copper ports are:
• 10HDx: 10 Mbps, half-duplex
• 10FDx: 10 Mbps, full-duplex
• 100HDx: 100 Mbps, half-duplex
• 100FDx: 100 Mbps, full-duplex
Possible port settings for 100FX (fiber) ports are:
• 100FDx (default): 100 Mbps, full-duplex
• 100HDx: 100 Mbps, half-duplex
Possible port settings for 10FL (fiber) ports are:
• 10HDx (default): 10 Mbps, half-duplex
• 10FDx: 10 Mbps, full-duplex
Possible port settings for Gigabit fiber-optic ports (Gigabit-SX and Gigabit-LX) are:
• 1000FDx (default): 1000 Mbps (1 GBPS), full duplex only
• Auto: The port operates at 1000FDx and auto-negotiates flow control with the
device connected to the port
To change the port speed on a transceiver port the switch must be rebooted
