Control Description
Port Specifies the port number to control.
Admin Enables or disables the port.
Auto Negotiation
Enables or disables auto-negotiation. When auto-negotiation is enabled, the port
negotiates with the link partner and works out speed, duplex operation, and flow
control. When auto-negotiation is disabled, port speed, duplex operation, and
flow control is programmable by the user.
Duplex Speed Indicates duplex state and speed of the port.
Flow Control
Turns flow control on or off. When flow control of the port is on, it sends out a
Pause frame or a Jam Packet if it is over-subscribed. When this port receives a
Pause Frame or Jam Signal, it will postpone sending for a certain period to send
out a frame by IEEE definition.
Default Priority
Assigns packet priority for packets arriving at the port without tagging. If the
packet comes in with tag or priority-tag, the priority is retrieved from the priority
field of the tag.
PVID
Assigns default port VLAN ID for the port. When the port receives a frame which
is untagged or priority tagged (VLAN ID = 0), the PVID will be used for
forwarding decision for these two kind of frame.
