industrial Ethernet switch - 19677 Accessible IP

The EDS-510A uses an IP address-based filtering method to control access to the EDS-510A units. Accessible IP Settings allows you to add or remove “Legal” remote host IP addresses to prevent unauthorized access. Access to the EDS-510A is controlled by IP address. If a host’s IP address is in the accessible IP table, then the host will be allowed access to the EDS-510A. You can allow one of the following cases by setting this parameter: Only one host with the specified IP address can access the EDS-510A E.g., enter “192.168.1.1/255.255.255.255” to allow access to just the IP address 192.168.1.1. Any host on a specific subnetwork can access the EDS-510A E.g., enter “192.168.1.0/255.255.255.0” to allow access to all IPs on the subnet defined by this IP address/subnet mask combination. Any host can access the EDS-510A Disable this function by deselecting the Enable the accessible IP list option.
