VLANs (Virtual Local Area Networks) are created on network switches, specifically through their management interfaces, which can be accessed via web interfaces, command-line interfaces, or network management software. VLANs are used to segment a physical network into multiple logical networks, improving security and reducing broadcast traffic by isolating devices within the same physical infrastructure based on functional or departmental requirements. This segmentation enhances network performance and simplifies network management by allowing different policies and configurations for each VLAN.

What is mean of shutdown vlan 17?
The command "shutdown vlan 17" is used in network configuration to disable VLAN 17 on a network switch. When executed, it effectively prevents any traffic from being forwarded through this VLAN, rendering it inactive. This can be useful for network management purposes, such as troubleshooting or reconfiguring the VLAN. To reactivate the VLAN, the command "no shutdown vlan 17" would be used.
What name is given to a vlan on an ieee 802.1q trunk whose frames are not tagged?
The name given to a VLAN on an IEEE 802.1Q trunk whose frames are not tagged is the "native VLAN." The native VLAN is used for untagged traffic on a trunk link, allowing devices that do not support VLAN tagging to communicate over the trunk. By default, VLAN 1 is designated as the native VLAN, but this can be changed to another VLAN as needed.
How can a VLAN help to improve voice traffic?
A Vlan can be used to reduced the amount of background chatter on the network from other devices not used by VOIP.
What is the purpose of the vlan database?
Vlan database is vlan.bat file which is stored in flash memory and earlier in NVRAM. It is used to store vlan information. we can take back up of this file.
The network administrator needs to remove the east-hosts vlan and use the switch port from that vlan in one of the existing vlans what two commands should be used when completely removing vlan 2 from?
no vlan XXX copy run star
How do you create VLAN step-by-step?
AnswerVLANs are created on Layer 2 switches to control broadcasts and enforce the use of a Layer 3 device for communications. Each VLAN is created in the local switch's database for use. If a VLAN is not known to a switch, that switch cannot transfer traffic across any of its ports for that VLAN. VLANs are created by number, and there are two ranges of usable VLAN numbers (normal range 1-1000 and extended range 1025-4096). When a VLAN is created, you can also give it certain attributes such as a VLAN name, VLAN type, and its operational state. To create a VLAN, use the following steps.1) Configure VTP. VTP is a protocol used by Cisco switches to maintain a consistent database between switches for trunking purposes. VTP is not required to create VLANs; however, Cisco has set it up to act as a conduit for VLAN configuration between switches as a default to make administration of VLANs easier. Because of this, you must first either configure VTP with a domain name or disable VTP on the switch.2) Create the VLAN. VLANs are created by number. The two ranges of VLANs are as follows: The standard range consists of VLANs 1 to 1000. The extended range consists of VLANs 1025 to 4096. Extended VLANs are currently supported only on switches running COS software version 6.1 or greater. When you create a VLAN, you have many options to consider. Many options are valid only for FDDI and Token Ring VLANs. Some of the items configured deal with options, such as private VLANs, which are discussed in other sections in this book. VLANs are created using the set vlan command for COS devices or with the vlan command in vlan database mode for IOS switches.
Which distinct type of VLAN is used by an administrator to access and configure a switch?
The distinct type of VLAN used by an administrator to access and configure a switch is called the "Management VLAN." This VLAN is specifically designated for management traffic, allowing administrators to connect to the switch for configuration purposes. Typically, it is assigned a specific VLAN ID and is separate from user data traffic to enhance security and manageability.
What protocols are used to configure trunking on a switch?
VLAN
Which two types of traffic are always transmitted as untagged frames?
Management traffic and native VLAN traffic are always transmitted as untagged frames. Management traffic is used for device configuration and monitoring, while native VLAN traffic is traffic that is not associated with any specific VLAN and is transmitted untagged within a VLAN network.
What does VLAN stand for?
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 VLANs, a switch can create the broadcast domain. This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain. Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.
What switch features are typically used with Voice Over Internet Protocol?
VLAN and PoE are used
What is the purpose of the switch command switch port access vlan 99?
the switchport access vlan 99 command is used to designate a specific VLAN for a switch port, allowing you to control how traffic on that port is treated and segregated from traffic on other ports and VLANs in the network. This is a fundamental configuration step in building and managing VLANs within a network infrastructure.
