of Ethernet 1 will be shown in LAN 1 only and the IP of Ethernet 2 will be shown in LAN 2 only.
To use port trunking for a dual LAN connection, see section (iii).
* TS-110, TS-119, TS-210, TS-219, TS-219P, TS-119P+, TS-219P+, TS-112, and TS-212
only have one LAN port and do not support dual LAN configuration or port trunking.
Network Parameters
Under "Network Parameters" on the TCP/IP Property page, configure the following settings:
 Network Speed: Select the network transfer rate according to the network environment
of the NAS. Select auto negotiation and the NAS will automatically adjust the transfer
rate.
 Obtain the IP address settings automatically via DHCP: If the network supports
DHCP, select this option and the NAS will automatically obtain the IP address and
network settings.
 Use static IP address: To use a static IP address for network connections, enter the IP
address, subnet mask, and default gateway.
 Jumbo Frame: "Jumbo Frames" refers to 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 network appliances support Jumbo Frames,
select the appropriate MTU value for the network environment. The NAS supports 4074,
7418, and 9000 bytes for MTU.
Note:
 Jumbo Frames is only valid in Gigabit networks. All of the connected network
appliances must enable Jumbo Frames and use the same MTU value.
 Jumbo Frames are only supported by certain NAS models. Refer to the software
specification page on the QNAP website for further details.
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 are located in different physical locations. The NAS can
join a VLAN and be configured as a backup storage of other devices on the same VLAN.
To join a VLAN, select "Enable VLAN" and enter the VLAN ID (a value between 0 and 4094.)
Keep the VLAN ID safe and make sure the client devices are able to join the VLAN. If you
forget the VLAN ID and cannot connect to the NAS, you will need to reset the network
settings by pressing the NAS reset button. Once the NAS is reset, the VLAN feature will be
