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

QoS Configuration Examples

Traffic Classes Defined Example

Example 12-2shows how to create a class map called class1 that matches incoming traffic entering interface fastethernet0.

Example 12-2 Class Interface Command Example

ML_Series(config)# class-map class1

ML_Series(config-cmap)#match input-interface fastethernet0

Example 12-3shows how to create a class map called class2 that matches incoming traffic with IP-precedence values of 5, 6, and 7.

Example 12-3 Class IP-Precedence Command Example

ML_Series(config)# class-map match-any class2

ML_Series(config-cmap)#match ip precedence 5 6 7

Note If a class-map contains a match rule that specifies multiple values, such as 5 6 7 in this example, then the class-map must be match-any, not the default match-all. Without the match-any class-map, an error message is printed and the class is ignored. The supported commands that allow multiple values are match cos, match ip precedence, and match ip dscp.

Example 12-4shows how to create a class map called class3 that matches incoming traffic based on bridge group 1.

Example 12-4 Class Map Bridge Group Command Example

ML_Series(config)# class-map class3

ML_Series(config-cmap)# match bridge-group 1

Traffic Policy Created Example

In Example 12-5, a traffic policy called policy1 is defined to contain policy specifications, including a bandwidth allocation request for the default class and two additional classes—class1 and class2. The match criteria for these classes were defined in the traffic classes (see the “Creating a Traffic Class” section on page 12-10).

Example 12-5 Traffic Policy Created Example

ML_Series(config)# policy-map policy1

ML_Series(config-pmap)# class class-default

ML_Series(config-pmap-c)# bandwidth 1000

ML_Series(config-pmap)# exit

ML_Series(config-pmap)# class class1

ML_Series(config-pmap-c)# bandwidth 3000

ML_Series(config-pmap)# exit

ML_Series(config-pmap)# class class2

ML_Series(config-pmap-c)# bandwidth 2000

ML_Series(config-pmap)# exit

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.
