Configuring IP on the OSC
Configuring IP on the OSC allows you to use one Cisco ONS 15530 node in the network to monitor all
the other Cisco ONS 15530 nodes in the network. The OSC is a point-to-point signal so any IP
configuration valid for point-to-point interfaces is usable.
IP addressing on the OSC can be configured two ways:
• An IP address for each OSC wave interface with each address on a separate subnet.
• An unnumbered address for the OSC wave interfaces that reference another numbered interface.
The IP address of the reference interface is used as the IP packet source address. Use a loopback
interface as the reference interface because it is always up. Configure IP address for each node in a
separate subnet.
Note You can alternatively use the IP address of the NME (network management Ethernet)
interface (fastethernet 0) for the reference address instead of the loopback interface.
To configure IP on an OSC wave interface, perform the following steps, beginning in global
configuration mode:
Command Purpose
Step 1
Switch(config)# interface loopback 1
Switch(config-if)#
Selects the loopback interface to configure and
enters interface configuration mode.
Step 2
Switch(config-if)# ip address ip-address
subnet-mask
Configures IP address and subnet for the interface.
Step 3
Switch(config-if)# exit
Switch(config)#
Exits interface configuration mode and returns to
global configuration mode.
Step 4
Switch(config)# interface fastethernet 0
Switch(config-if)#
Selects the NME interface to configuration and
enters interface configuration mode.
Step 5
Switch(config-if)# ip address ip-address
subnet-mask
Configures IP address and subnet for the interface.
Step 6
Switch(config-if)# exit
Switch(config)#
Exits interface configuration mode and returns to
global configuration mode.
Step 7
Switch(config)# interface wave slot/0
Switch(config-if)#
Selects the wave interface in subcard 0.
Step 8
Switch(config-if)# ip unnumbered loopback 1 Configures an unnumbered interface referencing
the loopback interface.
Step 9
Switch(config-if)# exit
Switch(config)#
Exits interface configuration mode and returns to
global configuration mode.
