Chapter 8 Management Network Connectivity
IP Networking Overview
8.1 IP Networking Overview
ONS 15310-MA 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 can create ONS 15310-MA SDH login node groups, which allow you to provision
non-data communications channel (DCC) connected nodes in a 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 15310-MA SDH to
serve as a gateway for ONS 15310-MA SDH nodes that are not connected to the LAN.
• You can create static routes to enable connections among multiple Cisco Transport Controller (CTC)
sessions with ONS 15310-MA SDH nodes that reside on the same subnet with multiple CTC
sessions.
• If ONS 15310-MA SDH nodes are connected to Open Shortest Path First (OSPF) networks, ONS
15310-MA SDH network information is automatically communicated across multiple LANs and
WANs.
• The ONS 15310-MA SDH proxy server controls the visibility and accessibility between CTC
computers and ONS 15310-MA SDH element nodes.
8.2 IP Addressing Scenarios
ONS 15310-MA SDH IP addressing generally has seven common scenarios or configurations. Use the
scenarios as building blocks for more complex network configurations. Table 8-1 provides a general list
of items to check when setting up ONS 15310-MA SDH nodes in IP networks.
Table 8-1 General P Troubleshooting Checklist
Item What to Check
Link integrity Verify that link integrity exists between:
• CTC computer and network hub/switch
• ONS 15310-MA SDH nodes (RJ-45 ports labeled LAN) and network
hub/switch
• Router ports and hub/switch ports
Node hub/switch
ports
Verify connectivity. If connectivity problems occur, set the hub or switch port
that is connected to the ONS 15310-MA SDH to 10 Mbps half-duplex.
Ping Ping the node to test connections between computers and ONS 15310-MA
SDH nodes.
IP addresses/subnet
masks
Verify that ONS 15310-MA SDH IP addresses and subnet masks are set up
correctly.
Optical connectivity Verify that ONS 15310-MA SDH optical trunk ports are in service and that a
DCC is enabled on each trunk port.
