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

Monitoring and Verifying QoS Configuration

Step 1

Step 2

Step 3

To attach a traffic policy to an interface, perform the following procedure in global configuration mode:

Command

Purpose

 

 

ML_Series(config)# interface

Enters interface configuration mode, and specifies the

interface-id

interface to apply the policy map.

 

Valid interfaces are limited to physical Ethernet and

 

packet-over-SONET (POS) interfaces.

 

Note

Policy maps cannot be applied to SPR interfaces,

 

 

subinterfaces, port channel interfaces, or Bridge

 

 

Group Virtual Interfaces (BVIs).

 

 

ML_Series(config-if)# service-policy

Specifies the name of the traffic policy to be attached to the

output policy-map-name

output direction of an interface. The traffic policy evaluates

 

all traffic leaving that interface.

 

 

ML_Series(config-if)# service-policy

Specifies the name of the traffic policy to be attached to the

input policy-map-name

input direction of an interface. The traffic policy evaluates

 

all traffic entering that interface.

 

 

 

Configuring CoS-Based QoS

The global cos commit cos-valuecommand allows the ML-Series card to base the QoS treatment for a packet coming in on a network interface on the attached CoS value, rather than on a per-customer-queue policer.

CoS-based QoS is applied with a single global cos commit cos-valuecommand, as shown in Table 12-3:

Table 12-3 CoS Commit Command

Command

Purpose

 

 

ML_Series(config)# cos-commit

Labels packets that come in with a CoS equal to or higher than

cos-value

the cos-valueas CIR and packets with a lower CoS as DE.

 

 

Monitoring and Verifying QoS Configuration

After configuring QoS on the ML-Series card, the configuration of class maps and policy maps can be viewed through a variety of show commands. To display the information relating to a traffic class or traffic policy, use one of the following commands in EXEC mode, as needed. Table 12-4describes the commands that are related to QoS status.

Table 12-4 Commands for QoS Status

Command

Purpose

 

 

ML_Series# show class-map name

Displays the traffic class information of the user-specified

 

traffic class.

 

 

ML_Series# show policy-map

Displays all configured traffic policies.

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.
