unauthorized access. Access to NPort W2250/2150 is controlled by IP address. That is, if a host’s
IP address is in the accessible IP table, then the host will be allowed to access the NPort
W2250/2150. You can set up one of the following cases by setting the parameters accordingly.
y Only one host with a specific IP Address can access the NPort W2250/2150

Enter an IP address (e.g., 192.168.1.0), and enter the Netmask (e.g., 255.255.255.0). Note
that this type of setting will allow access to all network hosts on a particular subnet.
