Chapter 12 Performance Monitoring

12.6.2 ASAP Card Ethernet Performance Monitoring Parameters

1.SONET path performance monitoring parameters increment only if IPPM is enabled. For additional information, see the “12.2 Intermediate-Path Performance Monitoring” section on page 12-2.To monitor SONET path performance monitoring parameters, log into the far-end node directly.

2.For information about troubleshooting path protection switch counts, refer to the Cisco ONS 15600 Troubleshooting Guide.

3.The normalized physical layer performance parameters are represented as a percentage of the nominal operating value, with 100 representing the nominal value

4.To set the threshold values for LBC, OPT, and OPR, and to reset the OPR nominal value for future calculation, refer to the Cisco ONS 15600 Procedure Guide.

5.As stated in Telcordia GR-253-CORE, the LBC (TCA) PM value is not appropriate for use with some optical transmitter technologies. Such is the case for Cisco's uncooled SR optical transmitters. The default LBC TCA provides safe operating parameter for both of Cisco's cooled and uncooled transmitters.

12.6.2 ASAP Card Ethernet Performance Monitoring Parameters

CTC provides Ethernet performance information, including line-level parameters, port bandwidth consumption, and historical Ethernet statistics. The ASAP card Ethernet performance information is divided into Ether Ports and POS Ports windows within the card view Performance tab window.

12.6.2.1 ASAP Card Ether Port Statistics Window

The Ethernet Ether Ports statistics window lists Ethernet parameters at the line level. The Statistics window provides buttons to change the statistical values. The Baseline button resets the displayed statistics values to zero. The Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which automatic refresh occurs. The ASAP Statistics window also has a Clear button. The Clear button sets the values on the card to zero, but does not reset the ASAP card.

During each automatic cycle, whether auto-refreshed or manually refreshed (using the Refresh button), statistics are added cumulatively and are not immediately adjusted to equal total received packets until testing ends. To see the final PM count totals, allow a few moments for the PM window statistics to finish testing and update fully. PM counts are also listed in the ASAP card Performance > History window.

Table 12-6defines the ASAP card statistics parameters.

ONS 15600 specifications

Cisco Systems ONS 15600 is a highly versatile optical networking platform designed to meet the demands of modern telecommunications and data services. This multiservice edge platform supports various transmission mediums and offers a wide array of features that enable efficient data transport. Ideal for service providers and large enterprises, the ONS 15600 is engineered to provide scalable and reliable optical transport solutions.

One of the notable features of the ONS 15600 is its capability to support multiple protocols, including SONET/SDH, Ethernet, OTN, and legacy TDM services. This flexibility allows users to tailor their networks according to specific service requirements while ensuring interoperability with existing infrastructure. The platform is designed to facilitate seamless service migration, accommodating both legacy and next-generation services.

The modular architecture of the ONS 15600 enhances its scalability. It allows for easy expansion by incorporating additional line cards or interface modules without requiring significant downtime. This modularity ensures that service providers can evolve their networks over time, responding to increasing bandwidth demands and new service offerings with ease.

Incorporating advanced technologies, the ONS 15600 employs Dense Wavelength Division Multiplexing (DWDM), significantly increasing the capacity of fiber networks by allowing multiple signals to be transmitted simultaneously over a single optical fiber. This capability helps to optimize fiber utilization and reduce operational costs. In addition, the platform supports Optical Transport Network (OTN) for improved error detection and correction, contributing to higher reliability and performance.

Another key characteristic of the ONS 15600 is its robust management capabilities. The platform can be managed through Cisco's Optical Networking Manager (ONM), providing a centralized interface for network configuration, monitoring, and troubleshooting. This enhances operational efficiency and minimizes downtime, allowing service providers to focus on delivering quality services to their customers.

The ONS 15600 also prioritizes security, offering various features like encryption and access control to safeguard sensitive data during transmission. With its combination of scalability, flexibility, and security, the Cisco ONS 15600 stands out as a reliable choice for organizations looking to enhance their optical networking capabilities while meeting the evolving demands of the digital landscape. Its commitment to quality and performance makes it a cornerstone of modern optical networks.
