designed to enhance Ethernet networking throughput and reduce the CPU utilization of
large file transfers by enabling more efficient larger payloads per packet.
Maximum Transmission Unit (MTU) refers to the size (in bytes) of the largest packet that
a given layer of a communications protocol can transmit.
The NAS uses standard Ethernet frames: 1500 bytes by default. If the network
appliances support Jumbo Frame setting, select the appropriate MTU value for the
network environment. The NAS supports 4074, 7418, and 9000 bytes for MTU.
Note: The Jumbo Frame setting is valid in Gigabit network environment only. All the
network appliances connected must enable Jumbo Frame and use the same MTU value.
Advanced Options
A Virtual LAN (VLAN) is a group of hosts which communicate as if they were attached to
the same broadcast domain even if they were located in different physical locations. The
NAS can be joined to a VLAN and configured as a backup storage of other devices on the
same VLAN.
To join the NAS to a VLAN, select “Enable VLAN” and enter the VLAN ID (a value
between 0 and 4094). Please keep the VLAN ID safe and make sure the client devices
are able to join the VLAN. If you forgot the VLAN ID and were not able to connect to the
NAS, you would need to press the reset button of the NAS to reset the network
settings. Once the NAS is reset, the VLAN feature will be disabled. If the NAS supports
two Gigabit LAN ports and only one network interface is configured to enable VLAN, you
may also connect to the NAS via the other network interface.
