Chapter 22 Management Connectivity Reference
22.2 IP Addressing Scenarios
•
ONS 15454s can be connected to Open Shortest Path First (OSPF) networks so ONS 15454 network
information is automatically communicated across multiple LANs and WANs.
•
The ONS 15454 proxy server can control the visibility and accessibility between CTC computers
and ONS 15454 element nodes.
22.2 IP Addressing Scenarios
ONS 15454 IP addressing generally has eight common scenarios or configurations. Use the scenarios as
building blocks for more complex network configurations.
provides a general list of items to
check when setting up ONS 15454s in IP networks.
22.2.1 Scenario 1: CTC and ONS 15454s on Same Subnet
Scenario 1 shows a basic ONS 15454 LAN configuration (
). The ONS 15454s and CTC
computer reside on the same subnet. All ONS 15454s connect to LAN A, and all ONS 15454s have DCC
connections.

General ONS 15454 IP Troubleshooting Checklist
Item
What to Check
Link integrity
Verify that link integrity exists between:
•
CTC computer and network hub/switch
•
ONS 15454s (backplane [ANSI] or MIC-C/T/P [ETSI] wire-wrap pins or
RJ-45 port) and network hub/switch
•
Router ports and hub/switch ports
ONS 15454
hub/switch ports
If connectivity problems occur, set the hub or switch port that is connected to
the ONS 15454 to 10 Mbps half-duplex.
Ping
Ping the node to test connections between computers and ONS 15454s.
IP addresses/subnet
masks
Verify that ONS 15454 IP addresses and subnet masks are set up correctly.
Optical connectivity
Verify that ONS 15454 optical trunk ports are in service and that a DCC is
enabled on each trunk port.
