They also connect to other parts of the network that are either logically segmented with the more traditional subnet approach or require access to remote sites across wide-area links. VLANs provide the following benefits: They reduce administration costs related to solving problems associated with moves, additions, and changes. check over here
VLAN and WLAN resources Learn different methods of creating VLANs on a WLAN in this expert response from Lisa Phifer. Troubleshooting VLANs Even after VLANs have been implemented properly and efficiently, it is inevitable that network administrators and managers will run into problems. They save money by using existing hubs. But lock-in... http://www.techexams.net/forums/ccna-ccent/21471-difference-between-port-based-static-port-centric-vlan.html
On the secured VLAN, the router restricts access to the VLAN as configured on both switches and routers. One problem of shared LANs is that they are relatively easy to penetrate. Frame filtering examines particular information about each frame. Each switch port can be assigned to a VLAN.
It's relatively easy to tell if a network device isn't performing. The problems associated with shared LANs and switches are causing traditional LAN configurations to be replaced with switched VLAN networking configurations. By grouping ports and users together across multiple switches, VLANs can span single-building infrastructures, interconnected buildings, or even wide-area networks (WANs). Although static VLANs require the administrator to make changes, they are secure, easy to configure, and straightforward to monitor.

This type of configuration substantially reduces the overall broadcast traffic, frees bandwidth for real user traffic, and lowers the overall vulnerability of the network to broadcast storms. https://supportforums.cisco.com/discussion/13030606/vlan VLANs logically segment the physical LAN infrastructure into different subnets (or broadcast domains for Ethernet).
Configuring VLANs for server virtualization VLANs and server virtualization go hand in hand. VLAN guide: Your VLAN configuration questions answered Understanding VLAN implementation and IP address assignment How can I configure 10 VLANs with five unmanaged switches? Important to any VLAN architecture is the ability to transport VLAN information between interconnected switches and routers that reside on the corporate backbone. VLANs are an effective mechanism for extending firewalls from the routers to the switch fabric and protecting the network against potentially dangerous broadcast problems.

The disadvantage is that it increases vulnerability to broadcast traffic across all switches, ports, backbone links, and users. A VLAN, or virtual (logical) LAN, is a local area network with definitions that map workstations based on anything except geographic location.
Thus, although one segment may have excessive broadcast conditions, the rest of the network is protected with a firewall commonly provided by a router.
