settings:

Network Speed:

Select the network transfer rate according to the network

environment to which the NAS is connected. Select auto negotiation and the NAS

will adjust the transfer rate automatically.

Obtain the IP address settings autom atically via DHCP:

If the network supports

DHCP, select this option and the NAS will obtain the IP address and network settings

automatically.

Use static IP address:

To use a static IP address for network connection, enter the

IP address, subnet mask, and default gateway.

Jum bo Fram e:

This feature is not supported by TS-509 Pro, TS-809 Pro, and TS-

809U-RP. "Jumbo Frames" refer to the Ethernet frames that are larger than 1500

bytes. It is 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.
