D-Link DSR Series Router

The default MTU size supported by all ports is 1500. This is the largest

packet size that can pass through the interface without fragmentation. This

size can be increased, however large packets can introduce network lag and

bring down the interface speed. Note that a 1500 byte size packet is the

largest allowed by the Ethernet protocol at the network layer.

The port speed can be sensed by the router when Auto is selected. With this

option the optimal port settings are determined by the router and network.

The duplex (half or full) can be defined based on the port support, as well as

one of three port speeds: 10 Mbps, 100 Mbps and 1000 Mbps (i.e. 1 Gbps).

The default setting is 100 Mbps for all ports.

The default MAC address is defined during the manufacturing process for the

interfaces, and can uniquely identify this router. You can customize each

WAN port’s MAC address as needed, either by letting the WAN port assume

the current LAN host’s MAC address or by entering a MAC address manually.
