Port Management

Port Configuration

This page allows to configure the operating mode of each physical port.

Auto

Auto-Negotiation Enable / Disable. If set to Enable, the Speed, Duplex

mode and Flow Control are negotiated automatically. If set to Disable, you

have to assign these parameters manually.

Speed

When Auto-Negotiation is set to Disable, you have to set the connection

speed for the selected ports. When Auto-Negotiation is set to Enable, this

item is read-only.

Duplex

When Auto-Negotiation is set to Disable, you have to set the connection

mode (Half or Full) for the selected ports. When Auto-Negotiation is set to

Enable, this item is read-only.

Pause

Flow Control in Full Duplex mode. When Flow Control is enabled, the

switch can synchronize the speed with its peer to avoid the packet loss

caused by congestion

Backpressure

Flow Control in Half Duplex mode. A condition wherein a switch causes a

transmitting device to hold off on sending data packets until the switch

bottleneck is eliminated.

Tx/Rx Capability

Enable / Disable port. The default is Enable. If set to Enable, the port can

freely transmit and receive packets. If set to Disable, there will no access

to the network through the selected ports.

Addr. Learning

Address learning is a service that characterizes a learning bridge, in

which the source MAC address of each received packet is stored so that

future packets destined for that address can be forwarded only to the

bridge interface on which that address is located.
