Description

The SET DEVICE SUBNET_MASK_PORT1 command enables you to specify the subnetwork mask for your type of Internet class. In general, the subnetwork mask is a 32-bit IP address with all ones in the network and subnet portions of the address and zeroes in the host portion.

For example, if the address of your Bridge Module is 151.104.6.10 (which is a Class B network 151.104.0.0) and your company has elected to use the third byte as the subnet identifier (in this example 6), the subnet mask is 255.255.255.0 (ff.ff.ff.00 in hexadecimal representation).
