dmt margin

To set upstream and downstream signal-to-noise ratio (SNR) margins for a DMT profile, use the dmt margin command. To reset this command to the default value, use the no form of this command.

Usage Guidelines

dmt-margin

Enter the upstream and downstream SNR margins in decibels. The range is

 

0 to 15.

 

 

Downstream: 6 dB

Upstream: 6 dB

Profile configuration.

This command was introduced.

 

 

Caution

 

This command causes the port to retrain when you change the parameter.

 

 

 

 

 

 

Setting a parameter to its current value does not cause a retrain. If a port is training when you change

 

 

this value, the port untrains and retrains to the new value.

 

 

 

 

Examples

 

In this example, the command sets the SNR margins of the default profile to 12 dB downstream and

 

 

6 dB upstream:

 

 

DSLAM# configure terminal

 

 

DSLAM(config)# dsl-profile default

 

 

DSLAM(config-dsl-prof)#dmt margin downstream 12 upstream 6

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.
