Setting Description (or Subfield and Description)
Management Interface Settings
System Name The name for the STM for purposes of identification and management. The default
name is the name of your model (STM150, STM300, or STM600).
IP Address Enter the IP address of the STM through which you will access the Web
Management Interface. The factory default IP address is 192.168.1.201.
Note: If you change the IP address of the STM while being connected through the
browser, you will be disconnected. You then need to open a new connection to the
new IP address and log in again. For example, if you change the default IP address
from 192.168.1.201 to 10.0.0.1, you need to enter https://10.0.0.1 in your browser
to reconnect to the Web Management Interface.
Subnet Mask Enter the IP subnet mask. The subnet mask specifies the network number portion of
an IP address. Unless you are implementing subnetting, use 255.255.255.0 as the
subnet mask.
Gateway Address Enter the IP address of the gateway through which the STM is accessed.
Primary DNS Specify the IP address for the primary DNS server.
Secondary DNS As an option, specify the IP address for the secondary DNS server.
MTU Settings
Maximum Transmission
Unit
The maximum transmission unit (MTU) is the largest physical packet size that a
network can transmit. Packets that are larger than the MTU value are divided into
smaller packets before they are sent, an action that prolongs the transmission
process. For most Ethernet networks the MTU value is 1500 bytes, which is the
default setting.
Note: NETGEAR recommends synchronizing the STM’s MTU setting with that of
your network to prevent delays in transmission.
