64 Configuring an Ethernet Port
Parameter Description
Media Synopsis: { 100TX, 10FL, 100FX, 1000X, 1000T, 802.11g, EoVDSL, 100TX Only,
10FL/100SX, 10GX }
Default: 100TX
The type of the port media.
State Synopsis: { Disabled, Enabled }
Default: Enabled
Disabling a port will prevent all frames from being sent and received on that port. Also,
when disabled link integrity signal is not sent so that the link/activity LED will never be
lit. You may want to disable a port for troubleshooting or to secure it from unauthorized
connections.
NOTE
Disabling a port whose media type is set to 802.11g disables the
corresponding wireless module.
AutoN Synopsis: { Off, On }
Default: On
Enable or disable IEEE 802.3 auto-negotiation. Enabling auto-negotiation results in
speed and duplex being negotiated upon link detection; both end devices must be auto-
negotiation compliant for the best possible results. 10Mbps and 100Mbps fiber optic
media do not support auto-negotiation so these media must be explicitly configured to
either half or full duplex. Full duplex operation requires that both ends are configured as
such or else severe frame loss will occur during heavy network traffic.
Speed Synopsis: { Auto, 10M, 100M, 1G }
Default: Auto
Speed (in Megabit-per-second or Gigabit-per-second). If auto-negotiation is enabled,
this is the speed capability advertised by the auto-negotiation process. If auto-
negotiation is disabled, the port is explicitly forced to this speed mode.
AUTO means advertise all supported speed modes.
Dupx Synopsis: { Auto, Half, Full }
Default: Auto
Duplex mode. If auto-negotiation is enabled, this is the duplex capability advertised by
the auto-negotiation process. If auto-negotiation is disabled, the port is explicitly forced
to this duplex mode.
AUTO means advertise all supported duplex modes.
Flow Control Synopsis: { Off, On }
Default: On
Flow Control is useful for preventing frame loss during times of severe network traffic.
Examples of this include multiple source ports sending to a single destination port or a
higher speed port bursting to a lower speed port.
When the port is half-duplex it is accomplished using 'backpressure' where the switch
simulates collisions causing the sending device to retry transmissions according to the
Ethernet backoff algorithm.
When the port is full-duplex it is accomplished using PAUSE frames which causes the
sending device to stop transmitting for a certain period of time.
LFI Synopsis: { Off, On }
Default: Off
Enabling Link-Fault-Indication (LFI) inhibits transmitting link integrity signal when the
receive link has failed. This allows the device at far end to detect link failure under all
circumstances.
