Configuring IP on Ethernetdcc Interfaces for the In-Band Message Channel
Verifying Connectivity on the OSC
To verify connectivity over the OSC, use the following EXEC command:
Example
The following example shows how to use Telnet to connect from node 1 to node 2 in the ring to another
node through the OSC:
Node1# telnet 10.1.2.2
Trying 10.1.2.2 ... Open
Node2> enable
Node2#
Configuring IP on Ethernetdcc Interfaces for the In-Band
Message Channel
Configuring IP on the in-band message channel 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 10-Gbps ITU trunk cards
and the 10-GE uplink cards support the in-band message channel.
IP addressing for the in-band message channel can be configured in two ways:
• An IP address for each ethernetdcc interface with each address on a separate subnet.
• An unnumbered address for the Ethernet 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. Refer also to “Interface Naming Conventions” section on page 2-4 for naming
conventions.
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 ethernetdcc interface, perform the following steps, beginning in global
configuration mode:
Command Purpose
telnet ip-address Connects to another node using the reference IP address
for the other node.
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.
