media is 1Gbps fiber, it is always 1000Mbps and the
duplex is full only. If the media is TP, the Speed/Duplex is
comprised of the combination of speed mode,
10/100/1000Mbps, and duplex mode, full duplex and half
duplex. The following table summarized the function the
media supports.
In Auto mode, no default value. In Forced mode, default
value depends on your setting.
Flow Control
When Auto Speed is selected on a port, this section
indicates the flow control capability that is advertised to
the link partner. When a fixed-speed setting is selected, that
is what is used. The Current Rx column indicates whether
pause frames on the port are obeyed, and the Current Tx
column indicates whether pause frames on the port are
transmitted. The Rx and Tx settings are determined by the
result of the last Auto-Negotiation.
Check the configured column to use flow control. This
setting is related to the setting for Configured Link Speed.
Maximum Frame Size
This module offers 1518~9600 (Bytes) length to make the
long packet.
Excessive Collision Mode There are two modes to choose when excessive collision
happened in half-duplex condition as below:
Discard - The “Discard” mode determines whether the
MAC drop frames after an excessive collision has
occurred. If yes, a frame is dropped after excessive
collision. This is IEEE Standard 802.3 half-duplex flow
control operation.
Restart: - The “Restart” mode determines whether the
MAC retransmits frames after an excessive collision has
occurred. If set, a frame is not dropped after excessive
collisions, but the backoff sequence is restarted. This is a
violation of IEEE Standard 802.3, but is useful in
non-dropping half-duplex flow control operation.
Power Control
The Usage column shows the current percentage of the
power consumption per port. The Configured column
allows for changing the power savings mode parameters
per port.
Disabled: All power savings mechanisms disabled.
ActiPHY: Link down power savings enabled.
PerfectReach: Link up power savings enabled.
