This video discusses the use of virtual LANs (VLANs) in networking. A virtual LAN is a concept used in networking to create separate, isolated networks. Devices that are connected to a virtual LAN can communicate with each other without interfering with devices that are connected to other virtual LANs. The default virtual LAN in most switches is known as the physical virtual LAN (PVID). This video demonstrates how to change the default virtual LAN on a switch.

00:00:00 Mike Panocki from Network Protocol Specialist discusses the benefits of using VLANs in network management. He also discusses the importance of having a wall of cable testers to help with certification and troubleshooting.
00:05:00 This video discusses the benefits of using virtual LANs (VLANs), and how to set them up properly. It explains that a network administrator can use VLANs to separate different types of traffic, such as video and voice, on different networks. The network administrator also discusses the importance of validating network settings.
00:10:00 In this video, the host explains the concept of vlans and how they can be used to separate networks on a single physical network. He also provides an example of how assigning a switch port to a vlan can allow for different networks to be created on that same physical network.
00:15:00 The video explains the difference between access ports and trunk ports, and how each type of port can be used in a virtual network. The video also explains the importance of using vlan tags when connecting devices to a virtual network.
00:20:00 This video explains the difference between tagging and trunking switches, and how to use vlans to create separate networks within a single network.
00:25:00 This video discusses the use of virtual LANs (VLANs) in networking. A virtual LAN is a concept used in networking to create separate, isolated networks. Devices that are connected to a virtual LAN can communicate with each other without interfering with devices that are connected to other virtual LANs. The default virtual LAN in most switches is known as the physical virtual LAN (PVID). This video demonstrates how to change the default virtual LAN on a switch.
00:30:00 VLANs are used to divide a network into different segments for better communication, and can be used for security purposes by separating devices into different, isolated segments.
00:35:00 The video discusses the concept of networks, specifically how they can be divided into smaller, more manageable pieces using virtual LANs (VLANS). Routers are used to connect different networks, and by understanding the different types of routers and their capabilities, it is easier to understand how vlans work. VLANs can be used to create separate networks for guests, employees, or other specific groups of users, which can help to keep the broadcast traffic within a specific area to a minimum.
00:40:00 The video discusses the use of network devices, such as switches and routers, to create networks with different levels of security. It explains that one way to create a secure network is to use vlans to segment devices and control who can access which devices. The presenter demonstrates this by sharing the story of a camera operator who had to reset the power on a camera multiple times because it stopped responding. By using a network monitoring tool like Etherscope, the camera operator was able to detect the vlans and reset the power on the camera without having to log in to the switch.
00:45:00 The video explains that networks can be divided into smaller parts called "vlans" and that each vlan has an associated number. The video goes on to say that it's important to plan out your vlans before you start deploying them, and that you should assign different vlans to different parts of your network. Finally, the video discusses a method for numbering vlans and how it can be aligned with a subnet.
00:50:00 This video discusses how to plan out your networks, including how to decide on which VLANs to use and how to document your networks.
00:55:00 The video discusses how network administrators can use discovery tools to identify devices and their associated IP addresses on a local network. The video also shows how to use a link spreader tool to connect to a switch and see the devices connected to the switch.

01:00:00 - 01:40:00

This video explains how to use VLANs to improve network security. The presenter demonstrates how to connect a phone to a network and use it as an iperf server, as well as how to print objects using a 3D printer.

01:00:00 This video discusses the use of virtual LANs (VLANs) and how they can be used to connect switches and ports together. Additionally, the video demonstrates how to use the ether scope to view information about network traffic on a port.
01:05:00 This video explains how to use network interfaces and VLANs on a switch. The user demonstrates how to connect a VoIP phone and a Link Runner G2 device to a network and verify that they are working. Finally, the user shows how to create and save profiles for different network scenarios.
01:10:00 This YouTube video explains how routers use VLANs to separate network traffic. There are a few things to keep in mind when setting up VLANs: you need a router that understands 802.1Q VLAN tagging, and you will need a separate port for each VLAN on the router.
01:15:00 In this video, network protocol specialist Mike Pinaki discusses VLANs and other networking concepts. Pinaki recommends that viewers check out his website, nps, for more information on his training sessions.
01:20:00 The video discusses VLANs, the Link Sprinter, and the Etherscope. The Link Sprinter is a front line tester that can also send email notifications of test results. The Etherscope can do network discovery, cable testing, and fiber testing. The Etherscope also has a camera and bluetooth capabilities.
01:25:00 The video discusses the use of network devices, such as VLANs and routers, to improve network security. The presenter demonstrates how to connect a phone to a network and use it as an iperf server, as well as how to print objects using a 3D printer.
01:30:00 This video discusses how to use a cable comb to organize and manage network cables. The video also includes information about 3D printing and using metal filament in prints.
01:35:00 In this video, the presenter explains the difference between a subnet and a vlan, and how they are both used in networking. They also discuss how a vlan can be used to create multiple subnets, and how a vpn can be used to route traffic between different subnets.
01:40:00 This video discusses the importance of VLANs, and how they can be used to protect networks from unauthorized access. It also shows how to set up a VLAN on a router, and how to create a power chord for use with multiple devices.
