Configuring Subnet Addressing

To define a subnet entry, the IP address has to be entered as the lower boundary
address of the subnet. Otherwise, only a host entry can be configured.
For example, a subnet with a mask of 255.255.255.192 requires one of the
following IP addresses, where xxx = any IP address:
T
T
T
T

Configuring Subnet Masks

After the IP address is entered, a default subnet mask is displayed. The default
subnet mask is based on the IP address entered and can be changed.
To configure the DSL card, a valid subnet must be used. When a Host entry is
input, any valid IP address results in a subnet mask of 255.255.255.255.
When a Subnet entry is entered, the valid subnet mask is based on the IP address
entered. A valid subnet mask must be in one of the following formats:
T
T
T
T
3-2
xxx.xxx.xxx .0
xxx.xxx.xxx .64
xxx.xxx.xxx .128
xxx.xxx.xxx .192
If the IP Address entered is . . .
xxx.xxx.xxx. 0
xxx.xxx. 0.0
xxx. 0.0.0
xxx.xxx.xxx.xxx
255.0.0.0
255. nnn. 0.0
255.255. nnn. 0
255.255.255. nnn
Where nnn must be: 0, 128, 192, 224, 240, 248, 252, or 254.
