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

Configuring Multicast Priority Queuing QoS

Table 12-5 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.

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.
