Port Configuration
Label
Description
Port
This is the logical port number for this row.
Link
The current link state is displayed graphically. Green indicates
the link is up and red that it is down.
Current Link Speed
Provides the current link speed of the port.
Configured Link
Speed
Select any available link speed for the given switch port.
Auto Speed selects the highest speed that is compatible with a
link partner.
Disabled disables the switch port operation.
Flow Control
When Auto Speed is selected for 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
Enter the maximum frame size allowed for the switch port,
including FCS. The allowed range is 1518 bytes to 9600 bytes.
Excessive Collision
Mode
Configure port transmit collision behavior.
Discard: Discard frame after 16 collisions (default).
Restart: Restart back-off algorithm after 16 collisions.
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.
Enabled: Both link up and link down power savings enabled.
Total Power Usage
Total power usage in board, measured in percent.
