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 14-7, 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 14-8, 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 14-8, this is the circuit between New Node, POS Port 0 and Adjacent Node 1, POS Port 1.)

•Configure the new ML-Series card to join the RPR and enable the POS ports, if the initial configuration file did not already do this.

•Enable the POS ports on the existing adjacent ML-Series cards that connect to the new ML-Series card. (In Figure 14-8, these are Adjacent Node 1, POS Port 1 and Adjacent Node 2, POS Port 0.)

15310-CL, 15310-MA specifications

Cisco Systems has established itself as a leader in the networking domain, offering a wide array of solutions to meet the needs of modern businesses. Among its impressive product lineup are the Cisco 15310-CL and 15310-MA routers, designed to provide advanced network performance and reliability.

The Cisco 15310-CL is a versatile platform that primarily serves as a carrier-class router aimed at supporting high-speed data and voice services. It is built to handle the demands of large enterprises and service providers, offering a robust design that ensures maximum uptime and performance. One of its standout features is its modular architecture, which enables users to customize their configurations based on specific application needs. This scalability allows for future expansion without the need for a complete hardware overhaul.

Key technologies integrated into the Cisco 15310-CL include high-density Ethernet interfaces and a comprehensive suite of Layer 2 and Layer 3 protocol support. The device is capable of supporting multiple types of connections, including TDM, ATM, and Ethernet. This flexibility makes it an ideal choice for organizations that require seamless migration between various service types. Moreover, with features such as MPLS (Multiprotocol Label Switching) support and advanced Quality of Service (QoS) mechanisms, the router ensures that critical applications receive the necessary bandwidth and low latency required for optimal performance.

In contrast, the Cisco 15310-MA focuses on access solutions, providing a cost-effective entry point for businesses looking to enhance their network capabilities. It is well-suited for smaller offices or branch locations that need reliable connectivity without the expense and complexity associated with larger systems. The device supports a range of access methods and provides essential features like firewall capabilities, VPN support, and comprehensive security measures to protect sensitive data.

Both models benefit from Cisco's commitment to security and manageability, offering features like enhanced encryption protocols and user authentication mechanisms that help safeguard networks against threats. Additionally, they can be managed through Cisco’s intuitive software tools, simplifying configuration and monitoring tasks for IT administrators.

The Cisco 15310-CL and 15310-MA are ideal solutions for businesses seeking to enhance their network infrastructure, ensuring firms can keep pace with evolving technology demands while maintaining a focus on security and performance. Their combination of advanced features, modular capabilities, and robust support makes them valuable assets in the networking landscape.
