Subnet Mask
Purpose: Defines the subnet mask, an internal TCP/IP protocol stack variable that is used to
separate the subnetwork address from the local IP address. The TCP/IP protocol stack
performs a bit-wise AND on the IP address and the subnet mask. Each address segment
represents one byte, where 255 converts to FF hex.
This computation is used to find out if the DCS 300 (UDP Plus) or host (TCP/IP) and
5020 are on different subnetworks. If the 5020 is on a different IP subnetwork than the
DCS 300 or host, you must set the subnet mask. The default subnet mask 255.255.255.0
means the 5020 uses a standard IP network mask. After you change this parameter,
suspend and resume the 5020 to make the change effective.
For example, if the IP address is 192.9.150.184 and the subnet mask is 255.255.255.0,
the subnetwork address is 192.9.150.0.
Configuration: Use one of these methods:

Yes Yes No
In the Configuration or Unit Management application, choose Configure and then
Network. Next, choose Radio or Ethernet, then IP Address, then Obtain IP Address Via
DHCP, and finally choose Subnet Mask. For help, see Chapter 3, “Configuring the
5020.”

SNMP OID: 1.3.6.1.4.1.1963.5.15.5.2.1.3.index
where index is the radio or I/O adapter card number.
Options: The subnet mask must be a valid IP address that consists of four separate numbers, each
separated by a period. Each address segment is a number from 0 to 255.
