Netmask
Setting Factory Default Necessity
E.g., 255.255.255.0 255.255.255.0 Required
A netmask is used to group network hosts into subnets. When a packet is sent out over the network,
the NPort W2250/2150 will use the netmask to check whether the desired TCP/IP host specified in
the packet is on the same subnet as the NPort. If the address is on the same subnet, a connection is
established directly between the NPort W2250/2150 and the host. If the host is not on the same
subnet, the packet is sent to the Gateway address.
Gateway
Setting Factory Default Necessity
E.g., 192.168.1.1 None Optional
A gateway is a network gateway that acts as an entrance to another network. Usually, the
computers that control traffic within the network or at the local Internet service provider are
gateway nodes. NPort W2250/2150 needs to know the IP address of your network’s default
gateway computer in order to communicate with the hosts outside the local network environment.
For correct gateway IP address information, consult your network administrator.
ATTENTION
In dynamic IP environments, the firmware will make 3 requests to the DHCP or BOOTP server
every 30 seconds until network settings are assigned by the DHCP or BOOTP server. The
Timeout for each try increases from 1 second, to 3 seconds, to 5 seconds. If the DHCP/BOOTP
Server is unavailable, the firmware will use the default IP address (192.168.126.254), Netmask,
and Gateway for IP settings.
