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.
What layer of osi model does vlan operate?
VLAN's, or virutal local area networks, appear at the application level or Level 7 o the OSI model. VLAN's use tagging or pot+tagging to route traffic to and from a specific area (like a specific departement in a business). VLAN technology relies on ethernet connectivity throughout the network it functions on (a more ubiquitious medium than standard trunking and TCIP, etc). VLAN's require an edge switch to tag the outgoing traffic and recieve the incomming traffic and allows you to prioritize traffic (tagged v/s untagged) so you can provide services like ip telephony, video sessions, SIP, etc.
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 is true about vlan?
VLAN is a custom network which is created from one or more local area networks. It enables a group of devices available in multiple networks to be combined into one logical network. The result becomes a virtual LAN that is administered like a physical LAN. The full form of VLAN is defined as Virtual Local Area Network.
Which two statements describe VTP transparent mode operation?
A switch running in VTP Transparent mode will not participate in VLAN synchronization. With VTP version 2, it will forward VLAN traffic out its trunk interfaces.
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 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.
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 types of collision domains do vlans break up?
VLANs (Virtual Local Area Networks) break up collision domains primarily within a switched network environment. Each VLAN creates a separate broadcast domain, which means that devices within one VLAN do not receive broadcast traffic from devices in another VLAN. This segmentation reduces unnecessary traffic and collisions, enhancing overall network performance. Additionally, since switches operate at Layer 2, each port connected to a device in a VLAN represents its own collision domain, further isolating traffic.
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.
When multiple VLAN are created do you need a router to move data across the VLAN even though the all VLAN are within one subnet?
No, router is not necassary. All traffic will transfer data within the network.
What is the IEEE VLAN standard?
The IEEE VLAN standard, specifically IEEE 802.1Q, defines a method for tagging Ethernet frames to support Virtual Local Area Networks (VLANs). This standard allows network administrators to segment a physical network into multiple logical networks, enhancing security and traffic management. By adding a VLAN tag to frames, devices can identify and segregate traffic based on defined VLAN IDs, facilitating better organization and efficiency within network infrastructures.
A device that filters data traffic at a network boun dery and reduce the amount of traffic on a LAN by dividing it into two segments?
The device you’re referring to is typically a router or a switch with VLAN (Virtual Local Area Network) capabilities. By segmenting the network into two or more parts, it reduces broadcast traffic and improves overall network performance. This segmentation helps isolate network issues and enhances security by controlling traffic flow between segments. Additionally, it allows for better management of network resources and can improve bandwidth utilization.
What is the basis for membership in a vlan?
Membership in a VLAN (Virtual Local Area Network) is typically based on factors such as port assignments on a switch, which can be configured to associate specific ports with designated VLANs. Additionally, VLAN membership can be determined by MAC address filtering or through protocols like GVRP (GARP VLAN Registration Protocol). This segmentation allows for improved network management, security, and traffic isolation within a larger network.
What are VLANs used for?
VLANs provide the capability so virtually segregate traffic on a network. VLANs work by tagging traffic packets and ensuring that packets with separate VLAN IDs are only available at ports which have been configured for that VLAN ID.
What is the difference between switch's interface and VLAN interface?
A switch's interface typically refers to the physical ports on the switch through which devices connect, allowing for data transmission within the same local network. In contrast, a VLAN (Virtual Local Area Network) interface is a logical interface associated with a specific VLAN, enabling Layer 3 IP routing and communication between different VLANs. While switch interfaces handle traffic for individual devices, VLAN interfaces manage traffic for groups of devices segmented by VLANs, enhancing network organization and security.
What describes a VLAN?
A VLAN, or Virtual Local Area Network, is a logical subgroup within a network that allows devices to communicate as if they are on the same physical network, regardless of their actual location. It enhances security and performance by segmenting traffic, reducing broadcast domains, and enabling better management of network resources. VLANs are typically configured on network switches and can support various network topologies and protocols. By isolating different types of traffic, VLANs help optimize network efficiency and improve overall security.
