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

Add an ML-Series Card into an RPR

Figure 15-8shows the RPR after the third node is added with the two new STS circuits and spans that will be added.

To add an ML-Series card to the RPR, you need to complete several general actions:

•Force away any existing non-ML-Series card circuits, such as DS-1, that use the span that will be deleted.

•Shut down the POS ports on the adjacent ML-Series cards for the STS circuit that will be deleted to initiate the RPR wrap.

•Test Ethernet connectivity between the access ports on the existing adjacent ML-Series cards with a test set to ensure that the RPR wrapped successfully.

•Delete the STS circuit that will be replaced by the new circuits. (In Figure 15-7, this is the circuit between Adjacent Node 2, POS 0 and Adjacent Node 1, POS 1.)

•Insert the new node into the ring topology if the node is not already part of the topology.

•Install the ML-Series card and load your initial configuration file or otherwise do an initial configuration of the ML-Series card.

•Ensure the new node is configured with RPR before its POS ports are manually enabled or enabled through the configuration file.

•Create an STS circuit from one of the POS ports of an existing adjacent ML-Series card to a POS port on the new ML-Series card. (In Figure 15-8, this is the circuit between Adjacent Node 2, POS Port 0 and New Node, POS Port 1.)

•Create a second STS circuit from one of the POS ports of the other existing adjacent ML-Series card to the remaining POS port on the new ML-Series card. (In Figure 15-8, this is the circuit between New Node, POS Port 0 and Adjacent Node 1, POS Port 1.)

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.
