Physical interfaces

General settings

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

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: 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.
DAD attempts: Number of consecutive Neighbor Solicitation messages sent while performing Duplicate Address Detection (DAD) on a tentative address.
Allowed RA servers: Remote access servers allowed to connect using the interface.
