9.2 ONS 15600 IP Addressing Scenarios
ONS 15600 IP addressing generally has eight common scenarios or configurations. Use the scenarios as
building blocks for more complex network configurations.

9.2.1 Scenario 1: CTC and ONS 15600s on the Same Subnet

Scenario 1 shows a basic ONS 15600 LAN configuration
computer reside on the same subnet. All ONS 15600s connect to LAN A, and all ONS 15600s have DCC
connections.

IP subnetting can create ONS 15600 node groups, which allow you to provision nodes in a network
that are not connected using the data communications channel (DCC).
Different IP functions and protocols allow you to achieve specific network goals. For example,
Proxy Address Resolution Protocol (ARP) enables one LAN-connected ONS 15600 to serve as a
gateway for ONS 15600s that are not connected to the LAN.
You can create static routes to enable connections among multiple CTC sessions with ONS 15600s
that reside on the same subnet but have different destination IP addresses.
If ONS 15600s are connected to Open Shortest Path First (OSPF) networks, ONS 15600 network
information is automatically communicated across multiple LANs and WANs.
General ONS 15600 IP Troubleshooting Checklist
What to Check
Verify that link integrity exists between:
If connectivity problems occur, set the hub or switch port that is
connected to the ONS 15600 to 10 Mbps half-duplex.
Ping the node to test connections between computers and ONS 15600s.
Verify that ONS 15600 IP addresses and subnet masks are set up
correctly.
Verify that ONS 15600 optical trunk ports are in service; DCC is
enabled on each trunk port.
