Chapter 11 Configuring Quality of Service on the ML-Series Card

QoS Configuration Examples

class-map match-any and class-map match-all Commands Example

This section illustrates the difference between the class-mapmatch-anycommand and the class-mapmatch-allcommand. The match-anyand match-alloptions determine how packets are evaluated when multiple match criteria exist. Packets must either meet all of the match criteria (match-all) or one of the match criteria (match-any) in order to be considered a member of the traffic class.

Example 11-6shows a traffic class configured with the class-mapmatch-allcommand.

Example 11-6 Class Map Match All Command Example

ML_Series(config)# class-map match-all cisco1

ML_Series(config-cmap)# match cos 1

ML_Series(config-cmap)# match bridge-group 10

If a packet arrives with a traffic class called cisco1 configured on the interface, the packet is evaluated to determine if it matches the cos 1 and bridge group 10. If both of these match criteria are met, the packet matches traffic class cisco1.

In a traffic class called cisco2, the match criteria are evaluated consecutively until a successful match criterion is located. The packet is first evaluated to the determine whether cos 1 can be used as a match criterion. If cos 1 can be used as a match criterion, the packet is matched to traffic class cisco2. If cos 1 is not a successful match criterion, then bridge-group 10 is evaluated as a match criterion. Each matching criterion is evaluated to see if the packet matches that criterion. When a successful match occurs, the packet is classified as a member of traffic class cisco2. If the packet matches none of the specified criteria, the packet is classified as a member of the traffic class.

Note that the class-mapmatch-allcommand requires that all of the match criteria must be met in order for the packet to be considered a member of the specified traffic class (a logical AND operator). In the example, cos 1 AND bridge group 10 have to be successful match criteria. However, only one match criterion must be met for the packet in the class-mapmatch-anycommand to be classified as a member of the traffic class (a logical OR operator).

Example 11-7shows a traffic class configured with the class-mapmatch-anycommand. In the example, cos 1 OR bridge group 10 OR ip dscp 5 has to be successful match criteria.

Example 11-7 Class Map Match Any Command Example

ML_Series(config)# class-map match-any cisco2

ML_Series(config-cmap)# match cos 1

ML_Series(config-cmap)# match bridge-group 10

ML_Series(config-cmap)# match ip dscp 5

match spr1 Interface Example

In Example 11-8, the SPR interface is specified as a parameter to the match input-interfaceCLI when defining a class-map.

Example 11-8 Class Map SPR Interface Command Example

ML_Series(config)# class-mapspr1-cos1

ML_Series(config-cmap)#match input-interface spr1

ML_Series(config-cmap)# match cos 1

ML_Series(config-cmap)# end

ML_Series# sh class-map spr1-cos1

Class Map match-all spr1-cos1 (id 3)

15310-CL, 15310-MA specifications

Cisco Systems has established itself as a leader in the networking domain, offering a wide array of solutions to meet the needs of modern businesses. Among its impressive product lineup are the Cisco 15310-CL and 15310-MA routers, designed to provide advanced network performance and reliability.

The Cisco 15310-CL is a versatile platform that primarily serves as a carrier-class router aimed at supporting high-speed data and voice services. It is built to handle the demands of large enterprises and service providers, offering a robust design that ensures maximum uptime and performance. One of its standout features is its modular architecture, which enables users to customize their configurations based on specific application needs. This scalability allows for future expansion without the need for a complete hardware overhaul.

Key technologies integrated into the Cisco 15310-CL include high-density Ethernet interfaces and a comprehensive suite of Layer 2 and Layer 3 protocol support. The device is capable of supporting multiple types of connections, including TDM, ATM, and Ethernet. This flexibility makes it an ideal choice for organizations that require seamless migration between various service types. Moreover, with features such as MPLS (Multiprotocol Label Switching) support and advanced Quality of Service (QoS) mechanisms, the router ensures that critical applications receive the necessary bandwidth and low latency required for optimal performance.

In contrast, the Cisco 15310-MA focuses on access solutions, providing a cost-effective entry point for businesses looking to enhance their network capabilities. It is well-suited for smaller offices or branch locations that need reliable connectivity without the expense and complexity associated with larger systems. The device supports a range of access methods and provides essential features like firewall capabilities, VPN support, and comprehensive security measures to protect sensitive data.

Both models benefit from Cisco's commitment to security and manageability, offering features like enhanced encryption protocols and user authentication mechanisms that help safeguard networks against threats. Additionally, they can be managed through Cisco’s intuitive software tools, simplifying configuration and monitoring tasks for IT administrators.

The Cisco 15310-CL and 15310-MA are ideal solutions for businesses seeking to enhance their network infrastructure, ensuring firms can keep pace with evolving technology demands while maintaining a focus on security and performance. Their combination of advanced features, modular capabilities, and robust support makes them valuable assets in the networking landscape.
