Traffic Class Commands

 

 

 

 

Command

 

Purpose

 

 

ML_Series(config)# class-mapclass-map-name

Specifies the user-defined name of the traffic class. Names can be a

 

 

maximum of 40 alphanumeric characters. If match-allor

 

 

match-anyis not specified, traffic must match all the match criteria

 

 

to be classified as part of the traffic class.

 

 

There is no default-match criteria.

 

 

Multiple match criteria are supported. The command matches either

 

 

all or any of the criteria, as controlled by the match-alland

 

 

match-anysubcommands of the class-mapcommand.

 

 

Note The ML-100T-8 supports a maximum of 126 user-defined

 

 

class maps, plus one default class map named

 

 

“class-default”. The ML-Series card on the ONS 15454

 

 

SONET/SDH supports a maximum of 254 user-defined

 

 

class maps, plus one default class map named

 

 

“class-default”.

 

 

ML_Series(config)# class-mapmatch-all

Specifies that all match criteria must be met for traffic entering the

class-map-name

 

traffic class to be classified as part of the traffic class.

 

 

ML_Series(config)# class-mapmatch-any

Specifies that one of the match criteria must be met for traffic

class-map-name

 

entering the traffic class to be classified as part of the traffic class.

 

 

ML_Series(config-cmap)# match any

Specifies that all packets will be matched.

 

 

ML_Series(config-cmap)# match bridge-group

Specifies the bridge-group-number against whose contents packets

bridge-group-number

are checked to determine if they belong to the class.

 

 

ML_Series(config-cmap)# match cos cos-number

Specifies the CoS value against whose contents packets are checked

 

 

to determine if they belong to the class.

 

 

ML_Series(config-cmap)# match input-interface

Specifies the name of the input interface used as a match criterion

interface-name

 

against which packets are checked to determine if they belong to the

 

 

class.

 

 

The shared packet ring (SPR) interface used in RPR (SPR1) is a

 

 

valid interface-name for the ML-Series card. For more information

 

 

on the SPR interface, see Chapter 15, “Configuring Resilient Packet

 

 

Ring on the ML-Series Card.”

 

 

The input-interfacechoice is not valid when applied to the INPUT

 

 

of an interface (redundant).

 

 

ML_Series(config-cmap)# match ip dscp

Specifies up to eight DSCP values used as match criteria. The value

ip-dscp-value

 

of each service code point is from 0 to 63.

 

 

ML_Series (config-cmap)# match ip precedence

Specifies up to eight IP precedence values used as match criteria.

ip-precedence-value

 

 

 

 

Creating a Traffic Policy

To configure a traffic policy, use the policy-mapglobal configuration command to specify the traffic policy name, and use the following configuration commands to associate a traffic class, which was configured with the class-mapcommand and one or more QoS features. The traffic class is associated

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.
