Configuration Tasks

Creating and Associating a DSL Profile with Each Port

Before starting this configuration task, install the 8xDMT line card. Refer to the Octal-Port DMT ATU-C Line Card FRU Installation and Configuration Notes for information on installing the 8xDMT line card.

Starting at the global configuration prompt, use the following procedure to associate a DSL profile with a port:

 

Command

Purpose

Step 1

 

 

DSLAM(config)# dsl-profile 8xDMT

Select the profile that you want to attach to the

 

 

selected port. The profile name 8xDMT is used as

 

 

an example.

Step 2

 

 

DSLAM(config-dsl-prof)# exit

Return to the global configuration prompt.

Step 3

 

 

DSLAM(config)# interface atm1/1

Enter interface configuration mode on the port

 

 

where you will associate the 8xDMT DSL profile.

 

 

Repeat this process on each port that you wish to

 

 

associate with a DSL profile.

Step 4

 

 

DSLAM(config-if)# dsl-profile 8xDMT

Associate the DSL profile 8xDMT with

 

 

atm interface 1/1.

Step 5

 

 

DSLAM(config-if)# exit

Return to the global configuration prompt.

 

 

 

Verifying the DSL Profiles

You can use the show dsl profile profile-namecommand to verify that a DSL profile is attached to a port. You can also use the show running-configurationcommand to verify that the DSL profile is associated with a port.

Tips If no DSL profile appears in the show running-configurationcommand output, the default DSL profile is enabled. See the “Command Reference” section on page 10 for the default configuration values.

Modifying the DSL Profile

Starting at the global configuration prompt, use the following procedure to modify the default bit rate, signal-to-noise ratio, DMT check bytes, and overhead framing parameters in your DSL profile:

Caution Before migrating from interleave mode to fast path, determine whether the deployed CPEs offer

support for the feature. The Cisco 600 series CPEs currently do not support fast path.

 

Command

Purpose

Step 1

 

 

DSLAM(config)# dsl-profile 8xDMT

Enter DSL profile configuration mode.

Step 2

 

 

DSLAM(config-dsl-profile)# dmt bitrate

Set a DMT bit rate of 3200 kbps downstream and 640 kbps

 

maximum fast downstream 3200 upstream 640

upstream on the fast path. Automatically configures the

 

 

interleaved path to 0 kbps.

8xDMT specifications

Cisco Systems’ 8xDMT, or "Eightfold Digital Multicast Technology," is a pioneering solution designed to optimize multicast traffic management and enhance the scalability of network performance. This technology comes into play primarily in video broadcasting, online gaming, and other applications that require the efficient distribution of data to multiple endpoints, significantly reducing the bandwidth use while improving overall network efficiency.

One of the primary features of Cisco 8xDMT is its ability to support multiple multicast streams concurrently. By using advanced algorithms, 8xDMT ensures that network resources are utilized efficiently, minimizing latency and maximizing throughput. This makes it particularly advantageous for service providers and organizations that deliver high-definition video content or require real-time data transmission across geographic locations.

Another notable characteristic of the Cisco 8xDMT is its integrated Quality of Service (QoS) capabilities. This feature allows for the prioritization of multicast traffic, ensuring that critical data packets are transmitted smoothly without delay, even during peak load times. The QoS management allows administrators to configure settings that guarantee minimal disruptions, providing end users with a seamless viewing or gameplay experience.

Additionally, Cisco 8xDMT takes advantage of Multicast Domain Name System (mDNS), which allows devices on the same network to discover and communicate efficiently. This not only aids in reducing the network load but also simplifies the management of multicast addresses, making it easier for organizations to scale their operations without significant overhead.

The technology also incorporates robust security features, including support for secure multicast transmissions. This ensures that sensitive data remains protected during distribution, addressing the increasing need for security in an era where cyber threats are prevalent.

Furthermore, Cisco Systems emphasizes interoperability with its 8xDMT platform, ensuring easy integration with existing network infrastructure. This is crucial for enterprises looking to modernize their systems without the need for extensive reinvestment in new hardware.

In conclusion, Cisco Systems’ 8xDMT stands out as a versatile and high-performance multicast solution designed to meet modern networking demands. With its ability to manage multiple streams, enforce QoS, simplify multicast management, and secure communications, it holds significant potential for transforming how organizations distribute data efficiently and effectively.
