In computer networking, a virtual LAN (VLAN) is a local area network (LAN) that groups together physically disparate network nodes. A VLAN has the same attributes as a physical LAN, but it allows for endpoints to be grouped together even if they reside on different physical switches.
VLANs are also used to create virtual machine (VM) networks. In this case, each VM is assigned to a VLAN. This allows for the creation of multiple isolated networks on a single physical infrastructure.
VLANs are implemented through the use of tags. Tags are added to network frames to identify which VLAN they belong to. When a frame is received by a switch, the switch looks at the tag to determine which VLAN the frame should be forwarded to.
Switches can be configured to allow or deny traffic between VLANs. For example, a switch can be configured to allow traffic between the accounting VLAN and the sales VLAN, but to deny traffic between the accounting VLAN and the HR VLAN.
VLANs can be configured manually or through the use of software-defined networking (SDN). SDN allows for the dynamic creation and configuration of VLANs.
Cisco ACI is a software-defined networking (SDN) solution that offers a comprehensive, policy-based approach to network automation and application delivery. Cisco ACI uses a centralized policy model to automate network configuration and application delivery, making it easy to deploy and manage complex network applications.
Cisco ACI offers a number of features that are well suited for virtual machine (VM) networks, including:
Centralized Policy Management - Cisco ACI uses a centralized policy model to automate the provisioning and management of network resources. This makes it easy to deploy and manage VM networks.
Application-Centric Infrastructure - Cisco ACI provides an application-centric infrastructure that enables the dynamic creation of VM networks. This allows for the rapid provisioning of network resources and reduces the complexity of network deployments.
Scalable and Reliable - Cisco ACI is designed to be scalable and reliable. It offers a number of features that allow it to scale to meet the needs of large VM networks.
Secure - Cisco ACI offers a number of security features that help to secure VM networks. These features include role-based access control, auditing, and encryption.
Flexible - Cisco ACI is highly flexible and can be deployed in a number of different ways. It offers a number of features that allow it to be deployed in both on-premises and cloud environments.
