Welcome to part 8 – let’s quickly recap what we have covered so far in this series:

  • Part 1 introduced this series and discussed what topics would be covered, as well as a very brief overview of ACI.
  • In part 2, I took a look at the fabric bring up process
  • Next, we took a tour through the APIC GUI to get us familiar with the interface.
  • Part 4 looked at some of the most important ACI constructs – app profiles, EPGs, contracts and filters.
  • We had a look at networking concepts in ACI in part 5.
  • In part 6, we discussed access policies and how they are used to provision ports.
  • Last time out in part 7, I walked through setting up basic connectivity between two bare metal hosts.

OK, so what’s next? In this part, we’ll discuss VMM Integration. What does this mean exactly? Firstly, VMM stands for Virtual Machine Manager – in other words, we are talking about integration with a VM management system such as VMware vCenter, Microsoft SCVMM and so on. At the time of writing this post, ACI supports integration with vCenter (others will be supported later), so this is what we’ll concentrate on here. I should also point out that we could also use the Cisco Application Virtual Switch (AVS) to achieve this integration, but I’m going to focus on using the regular VMware distributed virtual switch in this post.

Welcome back! In this instalment, I’ll look at how to get two bare metal hosts talking to each other in the fabric. In the last post, we talked about access policies. At the end of that post, we had created a number of policies and applied them to our switching nodes. If you recall, by doing that we had provisioned a range of VLANs on one or more ports on a leaf node, but we had not actually enabled any VLANs on a port. In order to do that, we need to create at least one EPG and associate it with a port.

Just a quick note to say that both my ACI sessions from Cisco Live Milan in January are available now for viewing online:

BRKACI-2345 – ACI: What We Have Learnt From Early Deployments

BRKACI-1789 – How To Perform Common Tasks In ACI

You’ll need a login to access both the slides and the videos.

Enjoy!
