Alarm Monitoring and Management

This chapter describes Cisco Transport Controller (CTC) alarm management. To troubleshoot specific alarms, refer to the Cisco ONS 15310-MA SDH Troubleshooting Guide. Chapter topics include:

10.1 Overview, page 10-1

10.2 Viewing Alarms, page 10-1

10.3 Alarm Severities, page 10-9

10.4 Alarm Profiles, page 10-9

10.5 Alarm Suppression, page 10-12

10.6 External Alarms and Controls, page 10-13

10.1Overview

Cisco Transport Controller (CTC) detects and reports SDH alarms generated by the Cisco

ONS 15310-MA SDH and the larger SDH network. You can use CTC to monitor and manage alarms at the card, node, or network level. You can set alarm severities in customized alarm profiles or suppress CTC alarm reporting. For a detailed description of the standard Telcordia categories employed by Optical Networking System (ONS) nodes, refer the Cisco ONS 15310-MA SDH Procedure Guide.

Note ONS 15310-MA SDH alarms can also be monitored and managed through Transaction Language One (TL1) or a network management system (NMS).

10.2 Viewing Alarms

You can use the Alarms tab to view card, node, or network-level alarms. This means that if a network problem causes two alarms, such as loss of frame (LOF) and loss of signal (LOS), CTC only shows the LOS alarm in this window because it supersedes LOF. (The LOF alarm can still be retrieved in the Conditions window.)

The Path Width column in the Alarms and Conditions tabs expands upon alarmed object information contained in the access identifier (AID) string (such as “VC-4-1-3”) by giving the number of synchronous transport signals (VCs) contained in the alarmed path. For example, the Path Width will tell you whether a Critical alarm applies to an VC3 or an VC4-16c. The column reports the width as a 1, 3, 6, 12, 48, etc. as appropriate, understood to be “VC-N.”

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.
