ONS 15454 IP Addressing Scenarios
4.2 ONS 15454 IP Addressing Scenarios
ONS 15454 IP addressing generally has seven common scenarios or configurations. Use the scenarios
as building blocks for more complex network configurations. Table 4-1 provides a general list of items
to check when setting up ONS 15454s in IP networks. Additional procedures for troubleshooting
Ethernet connections and IP networks are provided in Chapter 9, “Ethernet Operation.”
4.2.1 Scenario 1: CTC and ONS 15454s on Same Subnet
Scenario 1 shows a basic ONS 15454 LAN configuration (Figure 4-1). 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.
Note Instructions for creating DCC connections are provided in Chapter 5, “SONET Topologies” within
the BLSR, UPSR and linear ADM procedures.

Item What to check
PC/workstation Each CTC computer must have the following:
• Netscape 4.61 or Internet Explorer 5.0 or higher
• JRE 1.3.0_C (PC) or JRE 1.3.0_01 (Solaris) for Releases 2.2.2 or higher;
JRE 1.2.2_05 or higher (Windows), or 1.2.2_03 or higher (Solaris) for
Releases 2.2.1 or earlier
• Modified Java policy file
See the “Computer Requirements” section on page 2-2 for additional
information.
Link integrity 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
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
ONS 15454 IP addresses and subnet masks are set up correctly.
Optical connectivity ONS 15454 optical trunk ports are in service; DCC is enabled on each trunk
port
