Accessible IP Settings
NPort 5110 uses an IP address based filtering method to control access to itself.
Accessible IP Settings allows you to add or block remote host IP addresses to prevent
unauthorized access. Access to NPort 5110 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 5110. You
can allow one of the following cases by setting the parameter.
!
Only one host with a specific IP address can access the NPort 5110
Enter “IP address/255.255.255.255” (e.g., “192.168.1.1/255.255.255.255”).
!
Hosts on a specific subnet can access the NPort 5110
Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”).
