Chapter 2 Alarm Troubleshooting

2.7.14 APS-INV-PRIM

2.7.14 APS-INV-PRIM

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: OCN

The Optimized 1+1 APS Primary Facility condition occurs on OC-N ports in an optimized 1+1 protection system if the incoming primary section header does not indicate whether it is primary or secondary.

Note APS-INV-PRIM is an informational condition and does not require troubleshooting. If the APS switch is related to other alarms, troubleshoot these alarms as necessary using the procedures in this chapter.

2.7.15 APSMM

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: OCN

An APS Mode Mismatch failure alarm occurs on OC-3 ports when there is a mismatch of the protection switching schemes at the two ends of the span, such as being bidirectional at one end and unidirectional at the other. Each end of a span must be provisioned the same way: bidirectional and bidirectional or unidirectional and unidirectional.

If one end is provisioned for 1+1 protection switching and the other is provisioned for path protection switching, an APSMM alarm occurs on the ONS 15310-CL or ONS 15310-MA that is provisioned for 1+1 protection switching.

Clear the APSMM Alarm

Step 1 For the reporting system, in node view verify the protection scheme provisioning by completing the following steps:

a.In node view, click the Provisioning > Protection tabs.

b.Click the 1+1 protection group configured for the OC-3 or OC-12 ports.

The chosen protection group is the protection group that is optically connected (with data communication channel [DCC] connectivity) to the far end.

Step 2 Click Edit.

Record whether the Bidirectional Switching check box is checked.

Step 3 Click OK in the Edit Protection Group dialog box.

Step 4 Log into the far-end node and verify that the OC-3 or OC-12 port 1+1 protection group is provisioned.

Step 5 Verify that the Bidirectional Switching check box matches the checked or unchecked condition of the box recorded in Step 1. If not, change it to match.

Step 6 Click Apply.

Step 7 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1-800-553-2447).

ONS 15310-CL, 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.
