Step Three:
Configure IP
Use the following steps to configure the RAS 1500 interface (rm0/eth:1)
for IP networks. The IP network information is required for proper
operation.
1 Enter IP network information. The network address consists of the station
address and a subnet mask using this format:
nnn.nnn.nnn.nnn/A, B, C, H, 8-30 or nnn.nnn.nnn.nnn
The first four octets describe the IP station address, followed by the
subnet mask (contiguous) designator. You can specify the subnet by class,
numerical designation or in the IP address format. If you specify a Class C
mask, for example, this command generates a 255.255.255.0 subnet
value for you. If you specify the number of 1 bits in the mask, the
acceptable range is 8-30 (32 if a host).
The network address is considered invalid if the portion of the station
address not covered by the mask is 0, or if the station address plus the
mask is -1 (all 1s). Defining a numerical subnet is useful when your
classification falls in between classes.
To enter the IP network information, enter the following command:
add ip network <network name>
interface rm0/eth:1
address <station address/mask>
frame [ethernet_II | snap]
For example, to enter IP network information with the traditional subnet
mask format, use the following command:
add ip network backbone address 192.75.202.99/C interface
rm0/eth:1 frame ethernet_II
To enter IP network information in a numerical mask format, use the
following command:
add ip network backbone address 192.75.202.99/24 interface
rm0/eth:1 frame ethernet_II
To verify network settings, use the list networks command and check the
connection by using the
ping <ip address>
command.
