Private VLANs VACL trunking vulnerabilities port security

VLANs generally refer to single logical broadcast domains that segregate two switch ports and does not allow them to communicate at the Layer-2 level. In a basic VLAN configuration, it is mandatory to associate each VLAN with a different subnet so that the VLANs can be associated with unique subnets for performing inter-VLAN communication. Let's consider a scenario where we need to create a huge number of VLANs. If we do not have enough subnets to accommodate the VLANs, we won't be able to create the VLANs. Hence, from a scalability perspective, we need to create VLANs that can still be part of the same subnet. This can be fulfilled by using the concept of private VLANs.

In this chapter we will learn:

  • What is a private VLAN?
  • Access Control List.
  • VLAN hopping.
