Chapter 14 Configuring Resilient Packet Ring on the ML-Series Card

Add an ML-Series Card into an RPR

Step 13 Use a test set to verify that Ethernet connectivity still exists between the Ethernet access ports on Adjacent Node 1 and Adjacent Node 2.

Note The SPR interface and the Ethernet interfaces on the ML-Series card must be in a bridge group in order for RPR traffic to bridge the RPR.

Step 14 If the new node is not already an active node in the SONET ring topology, add the node to the ring. Refer to the “Add and Remove Nodes” chapter of the Cisco ONS 15454 Procedure Guide.

Step 15 If the ML-Series card in the new node is not already installed, install the card in the node. 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 16 Upload the initial startup configuration file for the new ML-Series card. If you do not have a prepared startup configuration file, manually create a startup configuration file.

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

Step 17 Build an STS circuit with a circuit state of In Service (IS) from the available POS port on

Adjacent Node 1 to the New Node, as shown in Figure 14-8. On the New Node, use the POS port with the interface-number that does not match the interface-number of the available POS port on Adjacent Node 1. For example, POS Port 0 on Adjacent Node 1would connect to POS Port 1 on the New Node.

For detailed steps for building the circuit, see the “Configuring CTC Circuits for RPR” section on page 14-7.

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.

Build an STS circuit with a circuit state of IS from the available POS port on Adjacent Node 2 to the remaining POS port on the New Node, as shown in Figure 14-8.

Start or resume a Cisco IOS CLI session for the ML-Series card in Adjacent Node 1, as shown in Figure 14-7.

Complete the following Cisco IOS configuration, beginning in global configuration mode:

Router(config)# interface pos

Enters interface configuration mode for the POS port at one

interface-number

endpoint of the first newly created circuit.

 

 

Router(config-if)# no shutdown

Enables the port.

 

 

Step 21 Start a Cisco IOS CLI session for the ML-Series card in Adjacent Node 2, as shown in Figure 14-7.

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.
