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, perform the following 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 14-9.

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.

Cabling and Configuring the Shelves

You can use configure up to eight shelves in a multiple shelf node. In a multiple shelf node, the shelves connect to each other with patch connections between the mux/demux cards. These patch connections carry the channels from one shelf to the other and then out to the trunk.

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:


	Command	Purpose
Step 1	Switch1(config)# interface {wave slot \| oscfilter slot/subcard \| thru slot/subcard \| wdm slot/subcard}	Selects the interface to configure and enters interface configuration mode.
Step 2	Switch(config-if)# topology neighbor {name node-name \| ip-address node-ip-address \| mac-address node-mac-address} {port {name port-name \| ip-address port-ip-address \| mac-address port-mac-address}}	Configures the network topology information for a neighboring node.
Step 3	Switch(config-if)# topology neighbor agent ip-address ip-address	Specifies the address of the network topology agent on a neighboring node.

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)# 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

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:


	Command	Purpose
Step 1	Switch1(config)# redundancy Switch1(config-red)#	Enters redundancy configuration mode.
Step 2	Switch(config-red)# associate group name Switch(config-red-aps)#	Specifies an APS group name and enters APS configuration mode. Note The group name is case sensitive.
Step 3	Switch(config-red-aps)# aps disable	Disables APS activity between the interfaces. Note For newly created APS groups, APS activity is disabled by default.
Step 4	Switch(config-red-aps)# aps working wavepatch slot/subcard/port	Configures the working path interface.
Step 5	Switch(config-red-aps)# aps protection wavepatch slot/subcard/port	Configures the protection path interface.
Step 6	Switch1(config-red-aps)# aps y-cable	Enables y-cable protection. The default state is no y-cable protection (disabled).
Step 7	Switch1(config-red-aps)# aps message-channel ip far-end group group-name ip-address address	Configures the APS group name and IP address on the remote node that supports the channel.
Step 8	Switch1(config-red-aps)# aps enable	Enables APS activity between the interfaces.

For more information on configuring y-cable line card protection, see the "Configuring Y-Cable Based Line Card Protection" section on page 12-10.

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:

Switch(config)# redundancy

Switch(config-red)# associate group Channel17

Switch(config-red-aps)# aps working transparent 1/0/0

Switch(config-red-aps)# aps protection transparent 2/0/0

Switch(config-red-aps)# aps y-cable

Switch(config-red-aps)# aps far-end group Channel17 ip-address 10.1.2.3

Switch(config-red-aps)# aps enable

Switch(config-red-aps)# exit

Switch(config-red)# associate group Channel18

Switch(config-red-aps)# aps working transparent 3/0/0

Switch(config-red-aps)# aps protection transparent 4/0/0

Switch(config-red-aps)# aps y-cable

Switch(config-red-aps)# aps far-end group Channel18 ip-address 10.1.2.3

Switch(config-red-aps)# aps enable

Switch(config-red-aps)# exit

Switch(config-red)# associate group Channel19

Switch(config-red-aps)# aps working transparent 7/0/0

Switch(config-red-aps)# aps protection transparent 8/0/0

Switch(config-red-aps)# aps y-cable

Switch(config-red-aps)# aps far-end group Channel19 ip-address 10.1.2.3

Switch(config-red-aps)# aps enable

Switch(config-red-aps)# exit

Switch(config-red)# associate group Channel20

Switch(config-red-aps)# aps working transparent 9/0/0

Switch(config-red-aps)# aps protection transparent 10/0/0

Switch(config-red-aps)# aps y-cable

Switch(config-red-aps)# aps far-end group Channel20 ip-address 10.1.2.3

Switch(config-red-aps)# aps enable

Switch(config-red-aps)# end

Switch# copy system:running-config nvram:startup-config

The following example shows how to configure channels 17 through 20 on shelf 3 of a multiple shelf node.

Shelf3(config)# redundancy

Shelf3(config-red)# associate group Channel17

Shelf3(config-red-aps)# aps protection transparent 2/0/0

Shelf3(config-red-aps)# aps y-cable

Shelf3(config-red-aps)# aps far-end group Channel17 ip-address 10.3.2.1

Shelf3(config-red-aps)# aps enable

Shelf3(config-red-aps)# exit

Shelf3(config-red)# associate group Channel18

Shelf3(config-red-aps)# aps working transparent 3/0/0

Shelf3(config-red-aps)# aps protection transparent 4/0/0

Shelf3(config-red-aps)# aps y-cable

Shelf3(config-red-aps)# aps enable

Shelf3(config-red-aps)# exit

Shelf3(config-red)# associate group Channel19

Shelf3(config-red-aps)# aps working transparent 7/0/0

Shelf3(config-red-aps)# aps protection transparent 8/0/0

Shelf3(config-red-aps)# aps y-cable

Shelf3(config-red-aps)# aps far-end group Channel19 ip-address 10.3.2.1

Shelf3(config-red-aps)# aps enable

Shelf3(config-red-aps)# exit

Shelf3(config-red)# associate group Channel20

Shelf3(config-red-aps)# aps working transparent 9/0/0

Shelf3(config-red-aps)# aps protection transparent 10/0/0

Shelf3(config-red-aps)# aps y-cable

Shelf3(config-red-aps)# aps far-end group Channel20 ip-address 10.3.2.1

Shelf3(config-red-aps)# aps enable

Shelf3(config-red-aps)# end
