Chapter 12 Configuring Quality of Service on the ML-Series Card

Configuring QoS

2.If the packet comes in with an assigned CoS, the assigned CoS replaces the default. If an IP packet originates locally, the IP precedence setting replaces the CoS setting.

3.The input policy map has a set-cosaction.

4.The output policy map has a set-cosaction (except for broadcast or multicast packets).

The RPR header contains a CoS value and DE indicator. The RPR DE is set for noncommitted traffic.

Configuring QoS

This section describes the tasks for configuring the ML-Series card QoS functions using the MQC. The ML-Series card does not support the full set of MQC functionality.

To configure and enable class-based QoS features, perform the procedures described in the following sections:

•Creating a Traffic Class, page 12-10

•Creating a Traffic Policy, page 12-11

•Attaching a Traffic Policy to an Interface, page 12-15

•Configuring CoS-Based QoS, page 12-16

For QoS configuration examples, see the “QoS Configuration Examples” section on page 12-17.

Creating a Traffic Class

The class-mapglobal configuration command is used to create a traffic class. The syntax of the class-mapcommand is as follows:

class-map [match-any match-all]class-map-nameno class-map [match-any match-all]class-map-name

The match-all and match-any options need to be specified only if more than one match criterion is configured in the traffic class. The class-mapmatch-allcommand is used when all of the match criteria in the traffic class must be met for a packet to match the specified traffic class. The class-mapmatch-anycommand is used when only one of the match criterion in the traffic class must be met for a packet to match the specified traffic class. If neither the match-allnor match-anykeyword is specified, the traffic class behaves in a manner consistent with class-mapmatch-allcommand.

To create a traffic class containing match criteria, use the class-mapglobal configuration command to specify the traffic class name, and then use the match commands in Table 12-1, as needed.

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.
