Getting started with PORT configuration


The Port Configuration screen defines speed, duplexing, and flow control operation for a port when auto-negotiation is off. When auto-negotiation is on, those data are negotiated from the link partner. Otherwise, enable or disable ports to control packet forwarding.


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 controls duplex speed for the port.

Flow Control turns flow control on or off.
When flow control for 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 VLAN ID of packet when packets arrive at the port for untag packet or priority tag packet.
