13.2 IP Addressing Scenarios
•
They can be connected to LANs through direct connections or a router.
•
IP 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 to serve as a
gateway for ONS 15454s that are not connected to the LAN.
•
Static routes can be created to enable connections among multiple CTC sessions with ONS 15454s
that reside on the same subnet.
•
ONS 15454s can be connected to Open Shortest Path First (OSPF) networks so that ONS 15454
network information is automatically communicated across multiple LANs and WANs.
•
The ONS 15454 SOCKS (network proxy protocol) proxy server can control the visibility and
accessibility between CTC computers and ONS 15454 element nodes.
13.2 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.
Table 13-1
provides a general list of items to
check when setting up ONS 15454 nodes in IP networks.
The TCC2P card secure mode option allows two IP addresses to be provisioned for the node: one for the
backplane LAN port and one for the TCC2P LAN (TCP/IP) port. Secure mode IP addressing examples
are provided in the
“13.2.9 IP Scenario 9: IP Addressing with Secure Mode Enabled” section on
page 13-20
. IP addresses shown in the other scenarios assume that secure mode is not enabled. If secure
mode is enabled, the IP addresses shown in the examples apply to the backplane LAN port. See the
“13.2.9 IP Scenario 9: IP Addressing with Secure Mode Enabled” section on page 13-20
for information
about secure mode, repeater (single IP address) mode, and configuration locks.
Table 13-1
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 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 (span) ports are in service and that a DCC
is enabled on each trunk port.
