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

Configuring Multicast Priority Queuing QoS

Table 11-5 CoS Multicast Priority Queuing Command

Command

Purpose

 

 

Router (config)# [no] cos priority-mcastcos-value

Creates a priority class of multicast traffic based on a multicast

{bandwidth-kbps mbps bandwidth-mbps percent

CoS value and specifies a minimum bandwidth guarantee to a

percent}

traffic class in periods of congestion.

 

 

cos-valuespecifies the CoS value of multicast packets which

 

will be given the bandwidth allocation. Matches only a single

 

CoS of traffic (not a range). Supported CoS range is 0 to 7.

 

A minimum bandwidth guarantee can be specified in kbps, in

 

mbps, or by a percentage of the overall available bandwidth.

 

Valid choices for the ML-Series card are:

 

• Rate in kilobits per second

 

• Rate in megabits per second

 

• Percent of total available port bandwidth (1 to 100)

 

Reentering the command with the same cos-valuebut a

 

different bandwidth rate will modify the bandwidth of the

 

existing class.

 

Reentering the command with a different cos-valuecreates a

 

separate multicast priority queuing class with a maximum of

 

two multicast priority queuing classes.

 

The no form of this command removes the multicast priority

 

queuing class.

 

Note The true configurable bandwidth in kilobits or megabits

 

per second is per port and depends on how the

 

ML-Series card is configured. The show interface

 

command shows the maximum bandwidth of a port (for

 

example, BW 100000 Kbit). The sum of all bandwidth

 

and priority actions applied to the interface, plus the cos

 

priority-mcast bandwidth, is not allowed to exceed the

 

maximum bandwidth of the port.

 

Note Attempting to configure a priority-mcast bandwidth

 

that exceeds the true configurable bandwidth on any

 

port will cause the priority-mcast configuration change

 

to fail, and the multicast priority queuing bandwidth

 

guarantee will not be changed.

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.
