Parameter description:
Speed: Set the speed and duplex of the port. For 1 Gbps fiber, the speed is always 1000 Mbps and full duplex. For twisted pair, the
speed/duplex is the combination of speed mode (10/100/1000Mbps), and duplex mode (full duplex and half duplex).

In Auto-negotiation mode, there is no default value. In Forced mode, the default value depends on your setting.
Flow Control: Choose from two flow control modes: Enable and Disable. If flow control is set to Enable, both users can send a PAUSE frame
to the transmitting device(s) if the receiving port is too busy to handle more traffic. When flow control is set Disable, the packet is dropped if
the traffic is too much to handle.
Maximum Frame: The maximum packet size is 1518–9600 (Bytes) long.
Excessive Collision Mode: If excessive collisions occur when the connection is half-duplex, choose Discard or Restart.
Discard: The “Discard” mode determines whether the MAC drop frames after an excessive collision has occurred. If set to Discard, a frame
is dropped after excessive collisions. This conforms to IEEE Std 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 Std 802.3, but is useful in non-dropping
half-duplex flow control operation.

4.3.2 Port Status
The Port Status function gathers each port’s current status information and reports its port number, media, link status, port state, auto-
negotiation status, speed/duplex, Rx Pause, and Tx Pause. Media type information for the module ports 7 and 8 is also offered (see Figure
4-14).
Function name:
Port Status
Function Description:
Report the latest updated status of all ports in this switch. When the status of any one of the switch’s ports changes, the new value(s) are
displayed. The current port status refreshes about every 5 seconds.
