Chapter 11 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 11-3:

Table 11-3 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 11-4describes the commands that are related to QoS status.

Table 11-4 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.

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.
