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 else can I help you with?
In a three-layer hierarchical network design which distribution layer function delineates broadcast domains?
routing between VLANs
Can cisco layer 2 support vlan?
Yes, Cisco Layer 2 switches support VLANs (Virtual Local Area Networks). VLANs allow network segmentation by creating separate broadcast domains within the same physical network infrastructure. This capability enhances network performance and security by isolating traffic among different groups of users or devices. Cisco's implementation of VLANs follows the IEEE 802.1Q standard, enabling the tagging of Ethernet frames for proper routing between VLANs.
How do you program vlans on a switch?
how to prgram vlans on a switch
Describes a network link that carries the traffic of multiple VLANs?
all VLANs
Switches can create by grouping a number of ports into a broadcast domain?
VLANs.
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.
How many VLANs can there be on a Catalyst 2600 series switch?
totally 1005 vlans we can create
How are VLANs and subnets related?
Although VLANs and subnets are quite different concepts, when using VLANs, there should be a one-to-one correspondence between the two. That is, every VLAN should be in a different subnet.Although VLANs and subnets are quite different concepts, when using VLANs, there should be a one-to-one correspondence between the two.

What VLANs are allowed across a trunk when the range of allowed VLANs is set to the default value?
all VLANsThe default is to allow all VLANs through the trunking ports.
Why network engineers value vlans include a discussion on reasons for using vlans?
Network engineers value VLANs for their flexibility. They can include ports from more than one switch or segment. Any type of node can belong to one or more VLANs.
How do you reduce network congestion?
There are several ways to reduce network congestion. Subnetting and adding routers will break up broadcast domains and traffic. Adding VLANs will do the same while adding security. Upgrading the speed of NICs and wiring, i.e. moving from 10BaseT to 100 or 1000, will reduce congerstion as will moving from half duplex transmissions to full duplex transmissions.
