• Administrative Duplex Mode—If Auto Negotiation is disabled, select Half
for half-duplex or Full for full-duplex operation.
• Admin Advertisement—If Autonegotiation is enabled, select the highest
port speed and duplex setting that you want the port to negotiate. If you
select Max Capacity, the port autonegotiates up to the highest port speed
and duplex setting supported by hardware.
• Flow Control—Select to enable IEEE 802.3x flow control. Flow control
reduces data loss when the port cannot keep up with the number of frames
being switched. When enabled, the switch can send a PAUSE frame to stop
traffic on a port if the amount of memory used by packets on the port
exceeds a preconfigured threshold. The paused port does not forward
packets for the period of time specified in the PAUSE frame. When the
PAUSE frame time elapses or memory utilization falls below a specified low
threshold, the switch enables the port to again transmit frames. When the
mode is set to half–duplex, back pressure is exerted; however, we
recommend that Flow Control be enabled.
• Member in LAG—Indicates whether the port is a member of a Link
Aggregation Group. See Link Aggregation for information on configuring
LAGs.
• MTU—Specify the maximum transmission unit size in bytes. The default
MTU is 1518 and the range is between 1518 and bytes.
