13.1 IP Networking Overview
13.1 IP Networking Overview
ONS 15454 SDH nodes can be connected in many different ways within an IP environment:
They can be connected to LANs through direct connections or a router.
IP subnetting subnetting can create multiple logical ONS 15454 networks within a single Class A,
B, or C IP network. If you do not subnet, you will only be able to use one network from your Class
A, B, or C network.
Different IP functions and protocols can be used to achieve specific network goals. For example,
Proxy Address Resolution Protocol (ARP) enables one LAN-connected ONS 15454 SDH to serve
as a gateway for ONS 15454 SDH nodes that are not connected to the LAN.
Static routes can be created to enable connections among multiple Cisco Transport Controller (CTC)
sessions with ONS 15454 SDH nodes that reside on the same subnet.
ONS 15454 SDH nodes can be connected to Open Shortest Path First (OSPF) networks so
ONS 15454 SDH network information is automatically communicated across multiple LANs and
WANs.
The ONS 15454 SDH proxy server can control the visibility and accessibility between CTC
computers and ONS 15454 SDH element nodes.
13.2 IP Addressing Scenarios
ONS 15454 SDH IP addressing generally has eight common scenarios or configurations. Use the
scenarios as building blocks for more complex network configurations. Table 13-1 provides a general
list of items to check when setting up ONS 15454 SDH nodes in IP networks.
Table 13-1 General ONS 15454 SDH IP Troubleshooting Checklist
Item What to check
Link integrity Verify that link integrity exists between:
CTC computer and network hub/switch
ONS 15454 SDH nodes (MIC-C/T/P wire-wrap pins or RJ-45 port) and
network hub/switch
Router ports and hub/switch ports
ONS 15454 SDH
hub/switch ports
If connectivity problems occur, set the hub or switch port that is connected to
the ONS 15454 SDH to 10 Mbps half-duplex.
Ping Ping the node to test connections between computers and ONS 15454 SDH
nodes.
IP addresses/subnet
masks
Verify that ONS 15454 SDH IP addresses and subnet masks are set up
correctly.
Optical connectivity Verify that ONS 15454 SDH optical trunk (span) ports are in service and that
a DCC is enabled on each trunk port.
