Change Ubuntu Server from DHCP to a Static IP Address

If the Ubuntu Server installer has set your server to use DHCP, you will want to change it to a static IP address so that people can actually use it.

 Changing this setting without a GUI will require some text editing, but that’s classic linux, right?

 Let’s open up the /etc/network/interfaces file. I’m going to use vi, but you can choose a different editor

Digital Voice Port Configuration

Overview

This article focuses on digital voice port configuration in relation to VoIP implementation. There are a number of different components that need to be designed and configured when setting up a VoIP network, one of which is the voice port. The voice port is located at the intersection of the network between the packet based network and the traditional telephony network. In addition to physically connecting these two network types, a voice port is responsible for correctly translating voice calls and signaling. As the name suggests, digital voice ports transport the voice information between devices using digital methods. This article focuses on T1 and E1 voice port configuration.

T1 and E1 Voice Port Types

Some background information on the operations of both T1 and E1 circuits is required to fully understand the digital voice port configuration details in this article. Both T1 and E1 contain a number of 64-kbps channels (DS0) which are used for each path of voice. A T1 circuit has a total of 24 of these channels, and an E1 has a total of 30 (usable).

How a Cisco Switch functions on an Ethernet network

Many of us use switches every day but never really think about how they work. Whether you are studying to become a CCNA or just want to learn more about how a switch really functions, this article is for you.

Hubs vs. Switches

Prior to switches, Hubs were the standard for connecting devices on a local area network (LAN). The problem with hubs was that everything that went through them had to share the bandwidth of the link, bandwidth was wasted because all traffic was sent to all devices, and there were a lot of collisions because the hub didn’t do anything to prevent them. A switch fixes these problems.

What is a VLAN? How to Setup a VLAN on a Cisco Switch

Have you ever wondered what a Virtual LAN (or VLAN) is or been unclear as to why you would want one? If so, I have been in your place at one time too. Since then, I have learned a lot about what a VLAN is and how it can help me. In this article, I will share that knowledge with you.

What is a LAN?

Okay, most of you already know what a LAN is but let’s give it a definition to make sure. We have to do this because, if you don’t know what a LAN is, you can’t understand what a VLAN is.

A LAN is a local area network and is defined as all devices in the same broadcast domain. If you remember, routers stop broadcasts, switches just forward them.

What is a VLAN?

As I said, a VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLAN’s, a switch can create the broadcast domain.

Congestion Management Configuration

Congestion Management Overview

As discussed in the VoIP Quality of Service (QoS) Basics article, one of the methods of controlling the amount of congestion on the network is to utilize congestion management techniques, primarily queue configuration. This article addresses the various congestion management techniques, and reviews the steps required to configure it on a network.

Congestion management techniques can be used alongside other Quality of Service (QoS) techniques to ensure that the traffic which requires a high level of service is able to get it. Congestion management techniques work by reducing the effect that network congestion has on the flow of traffic across the network; this is done with a number of different queueing mechanisms.

Congestion management, like classification and marking, is another subject area that is required for the completion of the CVOICE (642-437) exam. Congestion management, along with a carefully planned overall QoS plan, is essential when implementing multiservice networks.

Analog Voice Port Configuration

Overview

This article focuses on basic analog voice port configuration. When implementing a VoIP network, there are a number of different components that need to be designed and configured in order to make the whole solution work correctly. One of these many components, the voice port, is located at the intersection of the network between the packet based network and the traditional telephony network. Along with physically connecting together these two different network types, a voice port is responsible for correctly translating voice calls and signaling.

As the name suggests, analog voice ports transport the voice information between devices using analog methods.  The three main types of analog voice port types include Foreign Exchange Office (FXO), Foreign Exchange Station (FXS), and Ear and Mouth (E&M) (also called rEceive and TransMit or Earth and Magnet).
