# Configure Network Interface Card Settings

This panel allows you to configure the speed and duplex settings for the Network Interface Cards (NIC) that have been enabled in the server. MSL supports the following combinations of NICs:

- a "Local" adaptor for connection to the Local Area Network (LAN-only mode) or

- a "Local" adaptor for connection to the Local Area Network AND a "WAN" adapter for connection to the Wide Area Network (Network Edge mode) or

- a "Local" adaptor for connection to the Local Area Network AND a "WAN" adapter for connection to the Wide Area Network AND a “WAN” adapter bridged to the WAN interface of the firewall (Server-gateway with bridged interface mode).

To configure the Speed and Duplex settings of a NIC:

Note: For virtual deployments, the fields are read-only. You cannot configure the settings from this page.

1. Under Configuration, click Ethernet Cards.

2. Set the Auto Configuration field to Off, and then click Save.

3. Set the Speed and Duplex parameters, and then click Save. All other settings are read only. See the following table for descriptions of the settings.

   Note: Speed and Duplex are read only if the Ethernet card does not support multiple options.

Setting | Description
Link detected | Yes: NIC is connected to the network. No: NIC is not connected to the network.
MAC Address | Media Access Control address of the Network Interface Card
Driver | Driver (for example: tg3) of the Network Interface Card.
Speed | Data transfer rate. Available settings are determined by the Ethernet card. Only supported settings are displayed.
Duplex | Half-duplex: uses only one wire pair with a digital signal running in both directions on the wire. Full-duplex: uses two pairs of wires to establish a point-to-point connection between the transmitter of the transmitting device and the receiver of the receiving device. Full-duplex data transfer provides faster data transmissions than half duplex.
Auto Negotiation | Auto Negotiation is an Ethernet process that allows two connected devices to choose common transmission parameters, such as speed, duplex mode, and flow control. During this process, the connected devices first share these parameters and then choose the fastest transmission mode they both support. Select On to apply Auto Negotiation; select Off to configure the Speed and Duplex settings.
