COMBINNING VLAN-ACCESS LIST TO ENHANCE VLAN SECURITY EFFICIENT

Abstract

As the number of VLANs increases, the management of IP traffic which requires more basic level of security for network access becomes more difficult, then the network administrator have to need a technology can meet the requirements of network management as efficiency, cost, bandwidth, ... and manage also other VLANs better. VACLs are another good layer of security to help control who can talk to who, much like  access control lists that are in firewalls and Routers, however the difference is VACLs operate at layer two of the OSI model. There could be situations where you have multiple hosts on the same LAN and want to block traffic from reaching certain hosts within that same network.
