26 CHAPTER 2: U SING THE COMMAND LINE I NTERFACEStep Three:Configure IPUse the following steps to configure the RAS 1500 interface (rm0/eth:1)for IP networks. The IP network information is required for properoperation.1 Enter IP network information. The network address consists of the stationaddress and a subnet mask using this format:nnn.nnn.nnn.nnn/A, B, C, H, 8-30 or nnn.nnn.nnn.nnnThe first four octets describe the IP station address, followed by thesubnet mask (contiguous) designator. You can specify the subnet by class,numerical designation or in the IP address format. If you specify a Class Cmask, for example, this command generates a 255.255.255.0 subnetvalue for you. If you specify the number of 1 bits in the mask, theacceptable range is 8-30 (32 if a host).The network address is considered invalid if the portion of the stationaddress not covered by the mask is 0, or if the station address plus themask is -1 (all 1s). Defining a numerical subnet is useful when yourclassification falls in between classes.To enter the IP network information, enter the following command:add ip network interface rm0/eth:1address frame [ethernet_II | snap]For example, to enter IP network information with the traditional subnetmask format, use the following command:add ip network backbone address 192.75.202.99/C interfacerm0/eth:1 frame ethernet_IITo enter IP network information in a numerical mask format, use thefollowing command:add ip network backbone address 192.75.202.99/24 interfacerm0/eth:1 frame ethernet_IITo verify network settings, use the list networks command and check theconnection by using the ping command.
