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.

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.
