Chapter 3 Initial Configuration of the ML-Series Card

Cisco IOS on the ML-Series Card

During a soft reset, which reloads or warm restarts the ML-Series card, the ML-Series card checks the cache for a Cisco IOS image. If a valid and current Cisco IOS image exists, the ML-Series card decompresses and initializes the image. If the image does not exist, the ML-Series requests a new copy of the Cisco IOS image from the 15310-CL-CTX or CTX2500. Caching the Cisco IOS image provides a significant time savings when a soft reset is performed.

To use CTC to reset the ML-Series card with a hard reset or soft reset, at the CTC card-level view or node-level view, right-click on the ML-Series card and click Hard-reset Card or Soft-reset Card. A hard reset also requires that the ML-Series card is in the out of service (OOS) state, which is set under the Inventory tab. Then click Yes at the confirmation dialog that appears. You can also initiate a hard reset by removing and reinserting the ML-Series card. You can initiate a soft reset through Cisco IOS with the privileged EXEC reboot command. For TL1 commands, refer to the Cisco ONS SONET TL1 Command Guide.

Caution A soft reset or a hard reset on the Cisco ONS 15310 ML-Series card is service-affecting.

There are four ways to access the ML-Series card Cisco IOS configuration. The two out-of-band options are opening a Cisco IOS session on CTC and telnetting to the node IP Address and 2001. The two-in-band signalling options are telnetting to a configured management interface and directly connecting to the console port.

Opening a Cisco IOS Session Using CTC

Users can initiate a Cisco IOS CLI session for the ML-Series card using CTC. Click the IOS tab at the card-level CTC view, then click the Open IOS Command Line Interface (CLI) button. A window opens and a standard Cisco IOS CLI User EXEC command mode prompt appears.

Note A Cisco IOS startup configuration file must be loaded and the ML-Series card must be installed and initialized prior to opening a Cisco IOS CLI session on CTC. See the “Startup Configuration File” section on page 3-5for more information.

Telnetting to the Node IP Address and Slot Number

Users can telnet to the Cisco IOS CLI using the IP address and the port number (2000 plus the slot number).

Note A Cisco IOS startup configuration file must be loaded and the ML-Series card must be installed and initialized prior to telnetting to the ML-Series card. See the “Startup Configuration File” section on page 3-5for more information.

Note If the ONS 15310 node is set up as a proxy server, where one ONS 15310 node in the ring acts as a gateway network element (GNE) for the other nodes in the ring, telnetting over the GNE firewall to the IP address and slot number of a non-GNE or end network element (ENE) requires the user’s Telnet client to be SOCKS v5 aware (RFC 1928). Configure the Telnet client to recognize the GNE as the SOCKS v5 proxy for the Telnet session and to recognize the ENE as the host.

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.
