CPOC Series: L2 and L3 Migration into ACI

Migration into ACI is always a hot-topic! In this video, we’ll take you through several must-see ACI migration scenarios where we do the following: Migrate a VM’s portgroup from a standard vSwitch portgroup to a an ACI DVS-managed portgroup. We’ll move the layer-3 gateway from the traditional network into ACI (and back to traditional, and … More CPOC Series: L2 and L3 Migration into ACI

ACI NetCentric 2 AppCentric Using MicroSegmentation

In this blog post, I’ll discuss a method of moving from Network Centric ACI Deployment to APP Centric ACI deployment using combination of ACI Features: MicroSegmentation/PrefferedGroups/ContractMasters. When ACI Fabric is initially deployed, it is either deployed in a Greenfield or Brownfield method. Green Field means it’s a brand new deployment. Brown Field means that the … More ACI NetCentric 2 AppCentric Using MicroSegmentation

dev to prod: A network programmability demo with ACI

One of the main benefits of ACI is the flexibility it offers. In particular, how easy it is to take configuration we have already completed, copy it, and re-use it for something else! For this demo, we’ll take configuration from Tenant dev, and copy the entire policy configuration to make a new Tenant called Tenant … More dev to prod: A network programmability demo with ACI

STP and ACI: Intermittent packet loss due to TCNs

One issue that can arise when we connect ACI and Legacy STP environments is intermittent packet loss to ACI endpoints due to Spanning-tree TCNs. TCNs will trigger ACI to flush endpoints in the EPG on which the TCN was received. ACI does re-learn the endpoints based on normal data-plane learning, but if the TCNs are … More STP and ACI: Intermittent packet loss due to TCNs

Using MCP (MisCabling Protocol) for ACI

MisCabling Protocol (or MCP) detects loops from external sources (i.e., misbehaving servers, external networking equipment running STP) and will err-disable the interface on which ACI receives its own packet. Enabling this feature is a best practice and it should be enabled globally and on all interfaces, regardless of the end device. MCP limits the blast … More Using MCP (MisCabling Protocol) for ACI
