Chapter 15 Configuring Resilient Packet Ring on the ML-Series Card

Delete an ML-Series Card from an RPR

Step 16 Click the Circuits tab.

Step 17 Click the Circuits subtab.

Step 18 Identify the appropriate STS circuit by looking under the source column and destination column for the circuit entry that matches the POS ports at the endpoints of the second circuit to be deleted.

The circuit entry is in node-name/card-slot/port-numberformat, such as Node-1/s12(ML100T)/pPOS-0.

Step 19 Click the circuit entry to highlight it.

Step 20 Click Delete.

The confirmation dialog box appears.

Step 21 Click Yes.

Step 22 If the new node will no longer be an active node in the SONET ring topology, delete the node from the ring. Refer to the “Add and Remove Nodes” chapter of the Cisco ONS 15454 Procedure Guide.

Step 23 If the ML-Series card in the new node is to be deleted in CTC and physically removed, do so now. Refer to the “Install the Cisco ONS 15310-CL” or “Install the Cisco ONS 15310-MA” chapters of the Cisco ONS 15454 Procedure Guide.

Step 24 Build an STS circuit with a circuit state of IS from the available POS port on Adjacent Node 1 to the available POS port on Adjacent Node 2, as shown in Figure 15-10. For detailed steps on building the circuit, see “Configuring CTC Circuits for RPR” section on page 15-7.

Note A best practice is to configure SONET circuits in an east-to-west or west-to-east configuration, from Port 0 (east) to Port 1 (west) or Port 1 (east) to Port 0 (west), around the SONET ring.

Step 25 Start or resume a Cisco IOS CLI session for the ML-Series card in Adjacent Node 1.

Step 26 Complete the following Cisco IOS configuration for the ML-Series card in Adjacent Node 1, beginning

 

in global configuration mode:

 

 

 

 

a.

Router(config)# interface pos

Enters interface configuration mode for the POS port at one

 

interface-number

endpoint of the first newly created circuit.

 

 

 

b.

Router(config-if)# no

Enables the port.

 

shutdown

 

 

 

 

Step 27 Start a Cisco IOS CLI session for the ML-Series card in Adjacent Node 2.

Step 28 Complete the following Cisco IOS configuration on the Adjacent Node 2 ML-Series card, beginning in

 

global configuration mode:

 

 

 

 

a.

Router(config)# interface pos

Enters interface configuration mode for the POS port at one

 

interface-number

endpoint of the second newly created circuit.

 

 

 

b.

Router(config-if)# no

Enables the port.

 

shutdown

 

 

 

 

Step 29

Use a test set to verify that Ethernet connectivity exists on the RPR.

Step 30

Monitor Ethernet traffic and routing tables for at least one hour after the node deletion.

 

Stop. You have completed this procedure.

ONS 15310-CL, ONS 15310-MA, Cisco ONS 15310-MA specifications

Cisco Systems has long been a leader in networking and telecommunications technology, and among its impressive lineup of products, the Cisco ONS 15310 series stands out as an essential solution for optical networking. This series includes models such as the ONS 15310-MA, ONS 15310-CL, and ONS 15310-CA, each designed to meet the diverse needs of service providers and enterprises seeking to enhance their optical transport networks.

The Cisco ONS 15310-MA is an advanced multi-service platform designed for metropolitan area networks. It facilitates the seamless transport of data, voice, and video over optical networks. One of its main features is its ability to support a variety of interfaces, including Ethernet, SONET/SDH, and Wavelength Division Multiplexing (WDM), allowing users to integrate multiple services into a single platform. Additionally, the ONS 15310-MA supports advanced traffic management and Quality of Service (QoS) features to prioritize critical applications and ensure consistent performance.

The ONS 15310-CL variant is tailored for more specific applications, providing enhanced capabilities aimed at delivering carrier-grade services. It features a robust architecture that accommodates high-capacity traffic without compromising reliability. This model emphasizes low power consumption and a compact design, making it suitable for deployment in space-constrained environments. The ONS 15310-CL also supports a wide range of optical interfaces, making it highly flexible for various network configurations.

In terms of technologies, the Cisco ONS 15310 series leverages Optical Transport Network (OTN) capabilities, providing high efficiency and greater bandwidth utilization. OTN technology enables efficient error correction and adds resilience to the network through its built-in protection mechanisms. Furthermore, the series supports seamless integration with existing IP/MPLS networks, creating a cohesive infrastructure as organizations evolve their networking requirements.

One of the defining characteristics of the ONS 15310 series is its focus on scalability. Network operators can start with a modest deployment and gradually expand capacity as demand grows. This adaptability is complemented by Cisco's comprehensive management and monitoring tools, providing operators with real-time insights into network performance and facilitating proactive management.

In conclusion, the Cisco ONS 15310-MA and ONS 15310-CL models represent sophisticated solutions for modern optical networks. With their versatile features, advanced technologies, and robust design, they empower service providers and enterprises to build resilient, high-capacity networks that meet the demands of today’s data-driven world.
