Assigning IP Addresses

3.1 ASSIGNING IP ADDRESSES

IP addresses for each port must be unique. IP addresses are divided into classes based on what portion of the address is network or port information. The address classes are A, B, and C.

•Class A addresses are used in very large networks that support many ports. The first byte identifies the network and the other three bytes identify the node. The first byte of a class A address must be in the range 1-126. The address 100.125.110.10 would identify node 125.110.10 on network 100.

•Class B addresses are used for medium sized networks. The first two bytes identify the network and the last two identify the node. The first byte of a class B address must be in the range 128-191. The address 128.150.50.10 identifies node 50.10 on network 128.150.

•Class C addresses are used for small networks. The first three bytes identify the network and the last byte identifies the port. The first byte of a class C address must be in the range 192-223. The address 192.138.217.10 identifies node 10 on network 192.138.217.

To assign an IP address to a port, at the LCM prompt:

1.Type ipaddr <PORT-NUMBER> <IP ADDRESS>

For example, ipaddr 6 192.138.217.40 would set the IP address of Port 6 to 192.138.217.40. LCM responds by displaying the IP address table, as shown under the ipaddr command.

NOTE

Entering erase to erase the current FN10 configuration sets the IP address on Port 1 to 192.0.2.1 (default) when the FN10 is rebooted.
