Configuring Multiple Shelf Nodes
This chapter describes how to configure a multiple shelf node in a network topology. This chapter contains the following sections:
• Configuring Multiple Shelf Nodes
About Multiple Shelf Nodes
On a single Cisco ONS 15530 shelf, only 4 channels can be supported. By cascading multiple Cisco ONS 15530 shelves, up to 32 channels can be supported. You can use multiple shelf nodes in either a point-to-point topology or a ring topology. The OSCs (optical supervisory channels) can both connect to one shelf, or they can be split between the two shelves.
Configuring Multiple Shelf Nodes
To configure a multiple shelf node, follow these steps:
Step 1 Populate the shelves with the motherboards, cards, and processor cards.
Step 2 Connect the OADM modules with cables and configure the patch connections.
Step 3 Configure the client interfaces.
Step 4 Establish network access to both shelves.
For information on configuring network access, see the "Configuring IP Access on the NME Interface" section on page 3-3.
Step 5 Configure IP addresses on the OSC wave interfaces.
For information on configuring an IP address on the OSC wave interface, see the "Configuring IP on the OSC" section on page 12-8.
Step 6 Configure the network topology information for the connections between the two shelves.
Step 7 Configure APS (Automatic Protection Switching) on the shelves in the network that support the channels.
Configuring Patch Connections Between Shelves
To represent the three shelves as one node in the network topology, you must configure the patch connection between the shelves in the CLI (command-line interface). To configure these connections, use the following commands, beginning in global configuration mode:
Examples
The following example shows how to configure the patch connections between the OADM modules on the three shelves in the example node:
Shelf1(config)# interface wdm 0/0
Shelf1(config-if)# topology neighbor name node1 port name wdm 0/1
Shelf1(config-if)# topology neighbor agent ip-address 10.1.1.1
Shelf1(config-if)# exit
Shelf1(config)# interface thru 0/0
Shelf1(config-if)# topology neighbor name shelf2 port name wdm 0/0
Shelf1(config-if)# topology neighbor agent ip-address 10.2.2.2
Shelf1(config-if)# exit
Shelf1(config)# interface wdm 0/1
Shelf1(config-if)# topology neighbor name shelf2 port name thru 0/1
Shelf1(config-if)# topology neighbor agent ip-address 10.2.2.2
Shelf1(config-if)# exit
Shelf1(config)# interface thru 0/1
Shelf1(config-if)# topology neighbor name shelf3 port name thru 0/0
Shelf1(config-if)# topology neighbor agent ip-address 10.2.2.3

Shelf2(config-if)# exit
Shelf2(config)# interface wdm 0/1
Shelf2(config-if)# topology neighbor name shelf3 port name thru 0/1
Shelf2(config-if)# topology neighbor agent ip-address 10.2.2.3
Shelf2(config-if)# exit
Shelf2(config)# interface thru 0/1
Shelf2(config-if)# topology neighbor name shelf1 port name wdm 0/1
Shelf2(config-if)# topology neighbor agent ip-address 10.2.2.1
Shelf2(config-if)# exit
Shelf3(config)# interface wdm 0/0
Shelf3(config-if)# topology neighbor name Shelf2 port name thru 0/0
Shelf3(config-if)# topology neighbor agent ip-address 10.2.2.2
Shelf3(config-if)# exit
Shelf3(config)# interface thru 0/0
Shelf3(config-if)# topology neighbor name shelf1 port name thru 0/1
Shelf3(config-if)# topology neighbor agent ip-address 10.2.2.1
Shelf3(config-if)# exit
Shelf3(config)# interface wdm 0/1
Shelf3(config-if)# topology neighbor name Node3 port name thru 0/0
Shelf3(config-if)# topology neighbor agent ip-address 10.3.3.1
Shelf3(config-if)# exit
Shelf3(config)# interface thru 0/1
Shelf3(config-if)# topology neighbor name shelf2 port name wdm 0/1
Shelf3(config-if)# topology neighbor agent ip-address 10.2.2.2
Shelf3(config-if)# exit
Configuring APS
When a multiple shelf node is part of a network topology, the channels supported by it might require special configuration. On a multiple shelf node, the OSC might have only one connection or no OSC connections at all. For the APS channel protocol to function correctly, the shelves that support a channel must both have two OSC connections, or you must configure the APS group name and IP address information on the shelves.
To configure APS for a channel supported on a multiple shelf node without full OSC support, perform the following steps, beginning in global configuration mode:
For more information on configuring y-cable line card protection, refer to the "Configuring Y-Cable Based Line Card Protection" section on page 10-11.
Examples
For these examples, assume the following:
•Channels 17-20 terminate on the second shelf of the multiple shelf node.
•The second shelf of the multiple shelf node has no OSC support.
•The management IP address of the second shelf of the multiple shelf node is 10.1.2.3.
•The management IP address of the single shelf node is 10.3.2.1.
The following example shows how to configure channels 17-20 on the single shelf node:
