How do you overcome the disadvantages of a VLAN?
- Solve broadcast problem.
- Reduce the size of broadcast domains.
- Allow us to add additional layer of security.
- Make device management easier.
- Allow us to implement the logical grouping of devices by function instead of location.
What is the disadvantage of configuring a VLAN on a VLAN compatible switch?
Hubs do not have the capability to provide VLANs to individual ports, and VLANs can not be extended beyond the device port even if a switch capable of supporting VLANs is attached.
What are the advantages and disadvantages of VLANs?
A switched network delivers packets only to the intended recipients and packets only to other members of the VLAN. This allows the network administrator to segment users requiring access to sensitive information into separate VLANs from the rest of the general users regardless of physical location. • VLANs improve security by isolating groups.
What is the difference between a LAN and a VLAN?
The main difference between LAN and VLAN is that In LAN, the network packet is advertised to each and every device Whereas in VLAN, the network packet is sent to only a specific broadcast domain. The primary advantage of VLAN is that it reduces the size of broadcast domains.
How are VLANs used to reduce broadcast traffic?
VLANs do reduce broadcast traffic because the number of delivered broadcast packets is equal to the number of computers on the VLAN minus one. This can be helpful but unless there’s a serious problem (or an attack) it’s fairly rare for broadcast traffic to overwhelm a computer’s ability to ignore it.
Why do I need an additional Router for VLAN?
An injected packet may lead to a cyber-attack. Threat in a single system may spread a virus through a whole logical network. You require an additional router to control the workload in large networks. You can face problems in interoperability.
