<h3>Local interface (LCLIFC)</h3>

<dd>Specify the subnet mask associated with the local interface. See the <i>TCP/IP Fastpath Setup</i> book for general information about subnets.
|
|
<p>Subnetting provides the capability to partition an internet domain. Specify the mask for the network subnet and host address fields of the internet address that defines a subnet. The subnet mask is in the form, <i>nnn.nnn.nnn.nnn</i>, where <i>nnn</i> is a decimal number ranging from 0 through 255. The subnet mask must mask off all bits of the network class's network ID portion of the internet address. For example, a subnet mask of 255.255.255.0 defines a Class B subnet consisting of all bits in the network portion of the internet address (this is a given) and consisting of all bits in the third byte of an internet address. If the subnet mask is entered from a command line, it must be enclosed in apostrophes.
