How Does Cisco Application Centric Infrastructure (ACI) Work?
Cisco ACI is an SDN solution that defines its network infrastructure based upon network policies. To make this possible Cisco has created the ACI Fabric OS, which is run by all systems within the ACI network. This shared OS makes it possible for the various switches within the ACI network to translate policies into infrastructure designs.
Key Features and Benefits of ACI
Cisco ACI enables organizations to easily create a software-defined data center, which provides several benefits, including:
Augmenting Cisco ACI Security with Check Point
Cisco ACI provides a number of built-in security solutions. A partnership with Check Point enhances these protections to provide advanced threat prevention for ACI environments.
Cisco APIC
The Cisco Application Centric Infrastructure Controller or Cisco APIC is a hardware appliance that is essentially a UCS C220 M3 with a locked down image which is completely encrypted.
Cisco ACI Policy Model
Cisco ACI benefits from white-list policy model which means that no packets are allowed to flow between applications until it’s been specifically allowed access. Endpoint Groups can be set within the ACI for basically any construct, such as applications, virtual port groups, VLANs, etc.
Cisco ACI Service Graphs
Using a new protocol called OpFlex (as well as device packages) we would be able to take advantage of that declarative model referred to above with all sorts of Cisco and 3rd-party applications and appliances.
Application Network Profile
Contracts can be created between the tiers after we’ve set up EPGs, policies, and service graphs. All together and as an Application Network Profile, The EPGs will act as either a provider or consumer of these contracts which essentially connect the policies to the tiers with which they should be associated.
Cisco ACI Tenants
Micro-segmentation within the ACI model can be provided by assigning EPGs to tenants. Multi-tenancy provides complete isolation between tenants and ACI addresses not only fulfill the need for network virtualization but also hardware abstraction to create a stateless network in the entire data center.
Cisco Nexus 9500 ACI Switch
The Cisco Nexus 9500 switches can operate in one the following modes, depending on the operating system loaded and the line cards installed: NX-OS vs ACI mode. Also, the components of the Nexus 9508 chassis are common to both NX-OS and ACI mode: the chassis, the supervisor cards, power supplies, and fabric modules.
Hello World
This is an overview of what I think Cisco ACI actually is. It uses some examples from the lab environment to show you how the things look like when you start to work with ACI. There are other articles in the works which will be online soon and which will go in details through the real configuration of ACI and best practices while doing it.
What is this Cisco ACI Fabric?
Cisco ACI is a datacenter network Fabric. It actually means that it is a networking system of more networking L3 switches that have a modified, next-generation OS which enables them to be centrally provisioned and configured through APIC controller to work as one device from access port perspective.
APIC Controller
APIC controller is a centralized point for provisioning and configuration where we manage complete Fabric configuration.
Building ACI Fabric by using LLDP discovery from APIC
You get through the wizards and then the APIC is ready for you to connect to him with https. When connected, you go to Fabric tab and under Fabric membership, you will see that APIC (using LLDP) did find the first Leaf to which he is directly connected.
Now you have a big switch
At this point, the Fabric is up and running. The whole fabric is working as one big switch with all Leaf ports being access ports on that huge switch system. It is like a chassis switch with multiple line cards, but here each line card is represented by one Leaf switch.
