6: Basic Parameters Mode Select the direction (Full-Duplex or Half-Duplex) and speed (10, 100, or 1000 Mbit) of data transmission. The default is Auto, which allows the Ethernet port to auto-negotiate the speed and duplex with the hardware endpoint to which it is connected. MDI-X MDI & MDI-X are types of Ethernet interfaces (both physical and electrical/optical) in a computer network used to carry transmission. They must be connected using the right twisted pair cable so that the transmission pair on one end is linked to the receiving pair on the other end, and vice versa. In general, MDI ports connect to MDI-X ports via straight-through twisted pair cabling, and for MDI to MDI or MDI-X to MDI-X connections, crossover twisted pair cables are deployed. Each port in the switch can be configured for Manual MDI (connect a port to a device by using a straight through cable), Manual MDI-X (swap the port's transmit and receive pairs), or Auto (the port will detect if the connection requires a crossover and automatically chooses MDI or MDI-X to properly match the other end of the link - so it does not matter if a straight through or crossover cable is used). The default setting is Auto. The MDI-X column in the Port Status table shows the current operational MDI-X mode for each port. 4. Click Apply to save the port settings.

The sum of lengths of bad frames received, e.g., the sum of lengths of Rx - Undersize, Rx - Fragments, Rx - Oversize, Rx - Jabber, Rx - RxErr and Rx - FCSErr. The number of good frames received that have a Unicast destination MAC address. The number of good frames received that have a Broadcast destination MAC address. The number of good frames received that have a Multicast destination MAC address. This does not include frames counted in Rx - Pause nor does it include frames counted in Rx - Broadcast. The number of good frames received that have a Pause destination MAC address. This includes Priority Flow Control (PFC) Pause frames. The sum of lengths of all Ethernet frames sent. The number of frames sent that have a Unicast destination MAC address. The number of frames sent that have a Broadcast destination MAC address. The number of frames sent that have a Multicast destination MAC address. This does not include frames counted in Tx - Pause nor does it include frames counted in Tx - Broadcast. The number of Flow Control frames sent. This includes Pause and Priority Flow Control (PFC) Pause frames. The number of good frames received that have a Pause destination MAC address. This includes Priority Flow Control (PFC) Pause frames. Total frames received with a length of less than 64 octets but with a valid FCS. SLC™ 8000 Advanced Console Manager User Guide 88
