Assigning IP Addresses
Fast Network 10 User Guide Page 3-3
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.
