General settings

Physical interface
A physical interface is a port, for example, Port1, PortA, or eth0.
Network zone
Zone assigned to the interface.

Advanced settings

Interface speed
Interface speed for synchronization.
Note Speed mismatch between the device and third-party routers and switches may result in errors or collisions, disconnection, increased latency, or slow performance.
MTU (Maximum Transmission Unit) value, in bytes. The MTU is the largest packet size that a network can transmit. Packets larger than the specified value are divided into smaller packets before they are sent.
Override MSS
MSS (Maximum Segment Size), in bytes. The MSS is the amount of data that can be transmitted in a TCP packet.
Use default MAC address
Use the default MAC address of the interface. By default, the first port that is included as member port becomes the default MAC address.
Override default MAC address
Override the default MAC address of the interface and enter a new address. On factory reset, the address will be reset to the default MAC address.
